1.0 PREFACE The Atlantic Canada Conservation Data Centre (ACCDC) is part of a network of NatureServe data centres and heritage programs serving 50 states in the U.S.A, 10 provinces and 1 territory in Canada, plus several Central and South American countries. The NatureServe network is more than 30 years old and shares a common conservation data methodology. The ACCDC was founded in 1997, and maintains data for the jurisdictions of New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland and Labrador. Although a non-governmental agency, the ACCDC is supported by 6 federal agencies and 4 provincial governments, as well as through outside grants and data processing fees. URL: www.ACCDC.com. Upon request and for a fee, the ACCDC queries its database and produces customized reports of the rare and endangered flora and fauna known to occur in or near a specified study area. As a supplement to that data, the ACCDC includes locations of managed areas with some level of protection, and known sites of ecological interest or sensitivity. 1.1 DATA LIST Included datasets:

Filename Contents SOhioNS_6067ob.xls All Rare and legally protected Flora and Fauna in your study area SOhioNS_6067ob100km.xls A list of Rare and legally protected Flora and Fauna within 100 km of your study area SOhioNS_6067ma.xls All Managed Areas in your study area SOhioNS_6067ff.xls Rare and common Freshwater Fish in your study area (DFO database)

1.2 RESTRICTIONS The ACCDC makes a strong effort to verify the accuracy of all the data that it manages, but it shall not be held responsible for any inaccuracies in data that it provides. By accepting ACCDC data, recipients assent to the following limits of use: a) Data is restricted to use by trained personnel who are sensitive to landowner interests and to potential threats to rare

and/or endangered flora and fauna posed by the information provided. b) Data is restricted to use by the specified Data User; any third party requiring data must make its own data request. c) The ACCDC requires Data Users to cease using and delete data 12 months after receipt, and to make a new request

for updated data if necessary at that time. d) ACCDC data responses are restricted to the data in our Data System at the time of the data request. e) Each record has an estimate of locational uncertainty, which must be referenced in order to understand the record’s

relevance to a particular location. Please see attached Data Dictionary for details. f) ACCDC data responses are not to be construed as exhaustive inventories of taxa in an area. g) The absence of a taxon cannot be inferred by its absence in an ACCDC data response. 1.3 ADDITIONAL INFORMATION The attached file DataDictionary 2.1.pdf provides metadata for the data provided.

AQUATIC INVERTEBRATE HABITAT ASSESSMENT C & D DEBRIS LANDFILL/ MSW TRANSFER STATION,

YARMOUTH COUNTY, NOVA SCOTIA –Fall 2017–

for

Fracflow Consultants Inc., Dartmouth, Town of Yarmouth and

Yarmouth County, Solid Waste Park Management Authority, Yarmouth, Nova Scotia

INTRODUCTION The C & D Debris Landfill/MSW Transfer Station, the adjacent reclaimed landfill site, the compost facility and a petroleum contaminated soils remediation facility1 comprise the Yarmouth County Municipal Solid Waste Park, located on Hardscratch Road near the Town of Yarmouth, Yarmouth County, Nova Scotia. Nova Scotia Environment (NSE) requires the C & D Debris Landfill/Transfer Station to conduct an aquatic habitat assessment semi-annually to monitor impacts of site activities on adjacent watercourses. From 2008-early 2012, the program was carried out by Sprytech Biological Services and Dillon Consulting Ltd. acting on behalf of the proponents. Envirosphere Consultants Ltd. was contracted to continue the monitoring program, with sampling beginning with the fall of 2012, and including spring and fall 2013 to 2017. The results of the fall 2017 sampling period are presented in this report. METHODS Two unnamed streams drain the reclaimed landfill site and one stream drains the new C & D disposal facility. Sampling took place at two sites on one of the streams at the reclaimed landfill site, and at two locations draining the C & D Debris Landfill site. At each location, observations and photographs of the biological environment; sediment samples for stream invertebrates; and measurements of water quality parameters (temperature, dissolved oxygen, and pH) were collected (Figure 1). Biologist, Heather Levy, and Environmental Technician, Joy Baker, of Envirosphere Consultants conducted the sampling on October 24, 2017. Aquatic invertebrates in the streambed at the sites were sampled and identified to the lowest practical taxonomic level, typically to order, family and genus. Taxonomic groups were enumerated and total abundance determined for each sample. These were used to calculate several indices of benthic community health, which can be compared between sites and, over time, at each site (an index of community health is like a body mass index or an IQ which gives a single number which can be used to compare individuals or things). Indices calculated are all commonly used in studies of this kind and include: EPT ratio (ratio of abundance of mayflies (Ephemeroptera), caddisflies (Trichoptera), and stoneflies (Plecoptera), to total numbers of organisms); Total Abundance (number of animals in the sample); and Taxon Richness (number of taxa per sample).

1 The petroleum contaminated soils remediation facility became operational in May 2013.

The four sites were chosen because of their proximity to surface water sampling sites used in the surface water quality-monitoring program at the site. Sites IV1 and IV2 are located on an unnamed tributary running along the northern perimeter of the reclaimed landfill site (Figures 1 and 2). Site IV1 is near water sampling Site SW1. Sites IV3 and IV4 are located on the unnamed stream near the C & D Debris Landfill and petroleum contaminated soils remediation facility; Site IV3 is the upstream site near water sampling Site SW3; and Site IV4 is located downstream, down gradient from the sedimentation pond near SW4 (Figures 1 & 2). Water levels were comparable to last year2. Sampling and sample processing were consistent with methods used in previous surveys. Each site was sampled with a Surber sampler (30.5 x 30.5 cm). Samples were preserved immediately in 100% isopropanol diluted to approximately 70% with stream water and returned to the lab for sorting of animals from the samples and identification3. Temperature, dissolved oxygen and pH were measured at each site––temperature and oxygen were measured with a YSI Model 85 handheld oxygen meter, and a water sample (200 mL) was taken at each site for pH determination at Envirosphere’s accredited lab (CALA, 2017). Site descriptions included; substrate type, in-stream cover (% shade, % overhang), bank type and stability, depth and width. Photographs of the stream were taken looking upstream and downstream at each site, and a photo of the substrate was taken at all locations. SITE DESCRIPTIONS Site IV1 Site IV1 is located on an unnamed stream, downstream of the reclaimed landfill (the old landfill has been capped and a compost curing area is located there). The sampling site, as sampled in October 2017, is the same as the previous years, a slow run having a bottom substrate of mainly sand and minor amounts of gravel and cobble as well as fines. Orange iron flocculates were observed upstream of the sampling site on the bottom substrate as they were during other fall surveys (2013-2016). The stream channel is approximately 40% shaded by a mixed coniferous/deciduous (primarily fir and maple) canopy. There is minimal overhanging vegetation (nearly absent, < 1%) and occasional vegetation in the streambed as well as moderate amounts of detritus, tree leaves and woody debris. Banks are mainly stable with minimal undercutting and covered in mosses, sedges, grasses, ferns and occasional shrubs; slope approaches are low. The wet width was 0.75 m and the average depth 3.3 cm. Water temperature was 13.8 oC; dissolved oxygen (DO) was low 2.9 mg/L, with 27.8 % saturation; pH was 6.9 (Table 1). Site photos are presented in Appendix 1.

2 Site IV2 was almost dry, so sampling occurred 5-6 m downstream of original site as was done in 2014-2016. 3 Samples were washed over an 0.5 mm mesh sieve to remove fine particles (mud etc.) and animals were removed from the samples by a technician using a stereo microscope and identified to the lowest convenient taxonomic level (typically to family) using available taxonomic literature. A list of taxonomic references used is found in Appendix 3.

Site IV2 Site IV2 is located along the northern perimeter of the reclaimed landfill and is ~1.5 m downstream of an outflow from a large pond; upstream portions of the stream originate above Hardscratch Road. The normal sampling site was almost dry, as in 2014-2016 (water levels were low at the site and it was difficult to find a good sampling location) so samples were taken 5 – 6 m downstream. Bottom substrate was gravelly sand with fines and occasional cobble as well as in-stream detritus, tree leaves and woody debris. The stream channel is 40% shaded by a mixed coniferous/deciduous (spruce, larch, alder, birch and maple) canopy. Flow was minimal and there was negligible overhanging vegetation (nearly absent) present. Banks were low and vegetated with moss, ferns, flowering plants (i.e. aster) and grasses. The wet width was approximately 0.5 m, having a mid-channel depth of 7 cm. Water temperature was 15.2 oC; DO was low at 1.2 mg/L, with 12.2 % saturation; and pH was 5.7 (Table 1). Site photos are presented in Appendix 1. Site IV3 Site IV3 is located just upstream of Surface Water Site 3 (SW3) along the unnamed tributary near the new C & D Debris Landfill site. The stream crosses a cut line4 prior to flowing downstream toward a deep pool and then further to Site IV4. The site is a run located to the side of a cut line, and has a bottom substrate of gravelly sand with mud and occasional cobble and boulder. The stream channel is slightly shaded (15 %) by overhanging vegetation, primarily by grasses and sedges. Riparian areas upstream are forested with a mix of coniferous/deciduous (maple) trees. Blowdowns were noted in the area as in previous sampling periods. Water levels in the system were low and flow was minimal; and in-stream woody debris, occasional tree leaf and detritus, were observed. Banks were very low (non-existent in places particularly along the cut line) resulting in the water spreading out and filling in the ruts of the cut line. The wet width was about 0.75 m, having an average depth of 4.7 cm. Water temperature was 13.0 oC; DO was low at 3.3 mg/L, with 31.4 % saturation; and pH was 6.6 (Table 1). Site photos are presented in Appendix 1. Site IV4 Site IV4 is located downstream of Site IV3, east and down gradient of a sedimentation pond and close to surface water Site 4 (SW4). Water levels and flow were low. Sampling was conducted in a slow run approximately 2 m wide and 2.3 cm deep with a substrate of sandy gravel, cobble and boulder. There was some exposed in-stream vegetation on boulders; and in-stream woody debris, detritus and tree leaves occurred. The stream channel was about 40 % shaded by a mixed canopy of coniferous/deciduous (fir/maple/spruce/larch) trees. Slope approaches were low, and banks were mainly stable and vegetated with moss, ferns, tree seedlings and covered in fallen tree leaves and

woody debris. Water temperature was 12.8 oC; DO was low at 2.2 mg/L, with 20.2 % saturation; and pH was 6.3 (Table 1). Site photos are presented in Appendix 1. INTERPRETATION Water Quality Measurements Temperatures at all sites were warm (12.8 – 15.2 ºC), and characteristic of the season, warmest at Site IV2 and lowest at Site IV4 (Table 1). Dissolved oxygen levels were low (1.2 – 3.3 mg/L) (Table 1); lowest at site IV2 (Table 1). Acidity (pH) ranged from 5.7 – 6.9, all below neutral, with the most acidic conditions (i.e. 5.7) occurring at the upstream site, IV25. Benthic Invertebrate Communities Sites on the unnamed tributary within the reclaimed landfill site (Sites IV1 and IV2) had moderate to low abundance and diversity of stream invertebrates—4,202 and 781 individuals/m2, and 8 and 4 taxa, respectively (Table 2). Abundance at Site IV1 was largely due to high numbers of oligochaetes, although minor amounts of other species (e.g. alderflies/dobsonflies/fishflies (Megaloptera), crustaceans (copepods and the isopod, Caecidotea sp.), midge fly larvae (Chironomidae) and caddisfly larvae (Trichoptera)) were also present. Abundance at Site IV2 is attributed mainly to the presence of oligochaetes, as well as smaller numbers of dipterans (biting and non-biting midge fly and phantom crane fly larvae (Ptychopteridae)(Table 2). EPT ratios, which indicate suitable water quality associated with the presence of certain invertebrate taxa, was zero at Site IV2 (i.e. none of the EPT species were present) and low at Site IV1. The zero and negligible EPT taxa and high numbers of oligochaetes at both sites are indicative of stressed conditions, such as due to seasonal variability. Sites along the tributary within the active C & D Debris Landfill site (Sites IV3 & IV4) had low abundance (561 – 1661 individuals/m2, respectively) and moderate diversity (9 and 10 taxa, respectively) (Table 2). Oligochaetes, crustaceans (i.e. copepods and/or the isopod, Caecidotea sp), midge fly larvae, caddisfly larvae and mollusks (bivalves at Site IV3 and gastropods at Site IV4) contributed to the abundance at both sites; aquatic stonefly larvae (Plecoptera) and leeches (Hirudinea) were also present at Site IV4, but in lower numbers (Table 2). Sites IV3 and IV4 had low EPT ratios (3.9 and 7.9%, respectively). The moderate diversity at sites IV3 and IV4, the presence of caddisfly larvae at both sites and stonefly larvae at Site IV4 indicates acceptable water quality for benthic organisms. Comparison of 2017 vs Previous Monitoring EPT ratios this year were lower than 2016 fall samples at sites IV1 and IV3, zero at Site IV2 in both years and higher than 2016 values, at Site IV4 (Figures 3 & 4).

5 In fall of 2013, 2014, 2015 and 2016, the pH value at this site was 5.6, 6.0, 5.3 and 4.7, respectively.

CONCLUSIONS AND RECOMMENDATIONS Overall, physical conditions were acceptable for the maintenance of aquatic life and biological communities (benthic invertebrates) at the C & D landfill/MSW transfer station site. pH was above or at the guideline level of 6.5 at two sites; slightly below at Site IV4; and at Site IV2, well below the guideline at 5.7. DO was below the Freshwater Aquatic Life Guidelines (CCME 1999)6 at all sites. Despite chemical findings, however, benthic organisms typically undergo short-term changes or variations in abundance between sampling periods (during the year and between years) and the variability observed is consistent with natural variation. Abundance was highest at Site IV1 and lowest at Site IV3 and taxon richness was highest at Site IV4 and lowest at Site IV2 (4 taxa). Stressed conditions (dominance by a small number of individual groups (e.g. oligochaetes, chironomids (midge fly larvae), and/or crustaceans) and low EPT% ratio) occurred at all sites, though moreso at sites IV1 and IV2. These conditions, though, are more likely due to seasonal variability (i.e. low flow) than to landfill influences. The presence of groups of ‘pollution sensitive’ organisms such as Plecoptera, Trichoptera and mollusks and/or crustaceans (e.g. isopods and copepods) is indicative of acceptable water quality for benthic organisms. Crustaceans and Trichoptera were present at three of the four sites, mollusks at two sites and Plecoptera present at one site, which indicates suitable benthic invertebrate habitat. As noted in earlier reports, it is important to put stream protection measures in place along the cut line and the trail to groundwater monitoring wells adjacent to Site IV3 in order to prevent entry of equipment or personnel into the stream. The invertebrate assessments continue to provide useful information on conditions in the tributaries receiving flow from the reclaimed landfill or C & D debris landfill/MSW transfer site. Based on the monitoring requirements for the sites, the next invertebrate sampling event will be in the spring of 2018.

1.0 INTRODUCTION

The Yarmouth County Solid Waste Management Authority (YCSWMA) is proposing toconstruct and operate a new Asbestos Disposal Cell within the boundaries of the Municipal SolidWaste (MSW) Management Park that it owns and operates. A geotechnical investigation wascompleted at the site of the proposed new cell as a component of the Environmental Assessmentfor a Class I Undertaking under the Environmental Assessment Regulations of the Nova Scotia

Environment Act.

1.1 Site Location

The MSW Management Park is located at 1936 Hardscratch Road, South Ohio, YarmouthCounty. The general location of the site is shown in Figure 1. The new Asbestos Disposal Cellwill be approximately 100 metres by 100 metres in size. The location of that cell is shown inFigure 2. All figures referenced in this report can be found in Appendix 1.

1.2 Objectives and Scope

The objectives of the geotechnical investigation were to determine the thickness and nature ofthe subsurface materials, as well as the depth to groundwater within the footprint of the planneddisposal cell.

The scope of the investigation involved excavating five test pits to refusal, describing thephysical nature of the subsurface materials that were encountered, installation of stand pipes andin situ hydraulic conductivity testing, particle size analysis of selected representative samples,and preparation of this factual report.

1.3 Statement of Limitations

The findings and conclusions presented in this report are based exclusively on the observationsand physical data for the locations that were excavated and sampled. The reader must understandthat subsurface conditions may vary between and beyond the various sampling locations.


Fracflow Consultants Inc., File 803-41 - 2

Fracflow Consultants Inc. does not expressly guarantee that subsurface conditions between andbeyond defined sampling/monitoring locations do not vary from the results determined at thoselocations.

Notwithstanding the foregoing limitations, this report is believed to provide a professionalopinion of what is considered to be a reasonable representation of conditions that existed or existat the site of the planned Asbestos Disposal Cell. The initials or signature of a Principal ofFracflow Consultants Inc. on the Permit to Practice imprint indicates approval to submit thisreport to the YCSWMA.



2.0 PHYSICAL SETTING

2.1 Vegetation and Birds

A spring botanical survey of vascular plants was conducted by botanist, Ruth Newell (Newell,2018). The area within and around the footprint of the planned Asbestos Disposal Cell iswooded. The main tree species present are Balsam Fir, Larch, White Spruce, Black Spruce, RedMaple, and Showy Mountain Ash. There were no vascular plant species listed under eitherfederal species-at-risk legislation or provincial species-at-risk- legislation observed during thesurvey. In addition, non-listed vascular plant species of conservation concern were not observedduring the survey.

No species of conservation concern were detected during an owl survey and standard breedingbird surveys at the site (Envirosphere, 2018).

2.2 Soils and Surficial Materials

Undisturbed soils in the area of South Ohio have been mapped as part of the Liverpool SoilSeries, which consist of greyish brown sandy loam over yellowish brown sandy loam (Cann etal., 1960). Those soils form in areas with undulating to gently rolling topography, moderatestoniness and imperfect drainage. The present land use capability was described as fair to poorfor cropland and agricultural development (Cann et al., 1960).

Local soil conditions were inspected as part of the Archaeological Resource Impact Assessment(ARIA) (In Situ, 2018). The soils are made up of a brown-black, partially decomposed organiclayer (Ae, 10cm-0; Lot 1), above a grey sandy loam (A2, 0-5cm; Lot 2), over a brown sandyloam (B2, 5-20cm; Lot 3).1 A mottled combination of Lots 2 and 3 was also encountered(Lot2/3). Rocks were also encountered in many of the tests as well as a dense, friable,grey/white, rock-like soil (Lot 4). The area has been designated by the Department ofCommunities, Culture and Heritage as having low archaeological potential in response thepermit report for A2018NS022. The shovel testing showed that the soils within the study areawere undisturbed natural soils and did not contain any areas of disturbance that may have beencovering intact cultural layers.



The MSW Management Park is situated in a stony till plain where drumlins and pockets oforganic deposits are found. The till generally consists of a stony and sandy matrix derived fromlocal bedrock sources. The till plain usually varies in thickness from 2 to 20 m, but can reach upto 30 m in thickness where drumlin facies are present. The organic deposits are generally sedgepeat swamps of thickness less than two metres in depressions and low lying areas (Stea et al.1992).

2.3 Bedrock Geology

Bedrock underlying the MSW Management Park consists of grey, medium-grained, foliatedsyenogranite to monzogranite of the Brenton Pluton (Keppie, 2000). The pluton is situated in ashear zone that is oriented northeast-southwest. To the northwest of the pluton, the bedrock ispart of the White Rock Formation consisting of grey, biotite-bearing slate, phyllite, schist andmetasandstone interlayered with green mafic to intermediate lithic metatuff and tuffaceousmetasandstone and amphibolite. To the southeast of the pluton, the bedrock consists of theAcacia Brook Formation of the Halifax Group formed by dark grey, laminated slate with minor,thin beds and lenses of light grey metasiltstone where sulphide-bearing minerals are common(White, 2012).

The potential for acid rock drainage (ARD) to form as a result of the exposure of the graniticrocks beneath the MSW Management Park is considered to be low. If some rock fragments fromthe Acacia Brook Formation are present in the surficial materials, localized ARD is possible.

2.4 Topography and Drainage

The footprint of the planned Asbestos Disposal Cell is generally flat to gently undulating.Surface elevations decrease from approximately 69 m on the west side to 65 m on the east sideand, therefore, the expected directions of runoff and shallow groundwater flow are from west toeast. There are no water courses or standing water within the boundaries of the proposed cell.



3.0 FIELD METHODS

3.1 Timing of Field Work

The field portion of the geotechnical investigation was conducted on August 14 and 15, 2018after the completion of the bird survey, wetlands/botanical survey and ARIA. Those surveysconfirmed that there were no sensitive site features, plants, birds or animals in the area thatwould otherwise prevent the work from being carried out, or that would require any unusualmitigative measures to be developed and employed. The site owner did conduct a visual surveyof the wooded areas in early August, prior to cutting trees for excavator access, to confirm theabsence of nesting birds. No nests or nesting birds were observed.

3.2 Surveying and Site Clearing

The boundaries of the planned Asbestos Disposal Cell and associated ground elevations wereestablished by Acker & Doucette Surveying. In early August 2018, trees were removed from a3 m to 4 m wide path through the centre of the planned cell and along the southern and northernboundaries of the proposed Asbestos Disposal Cell to permit excavator access.

3.3 Test Pit Excavation

Five test pits were excavated using a track-mounted CAT 308C excavator, equipped with astandard duty, 0.6 m (24 inch) wide bucket and finger. Those test pits were designated TP1through TP5 as shown in Figure 3. The goal of the excavation work was to inspect subsurfaceconditions across the footprint area to the maximum reach of the excavator or until refusaloccurred. The maximum reach of the excavator was approximately 3.6 m (12 feet) and refusaloccurred before the maximum reach was achieved at each location.

The subsurface stratigraphy exposed along the walls of each test pit was visually logged in thefield by the supervising technician. Soil descriptions were prepared on the basis of variations incolour, moisture content, relatively density and grain size and a graphical test pit log wasprepared. Samples representative of the different soil types were bagged and submitted to AGATLaboratories for particle-size determinations. Grain-size distribution plots were prepared by



Fracflow using the laboratory data and the samples were classified according to the Unified SoilClassification System and the Canadian Foundation Engineering Manual (CFEM, 1992). Soilclassifications using CFEM terminology are included on the test pit logs.

Note that AGAT defined gravel as the percent passing the 2 mm sieve. The CFEM approachrecognizes gravel as particles larger than 4.75 mm, which is the definition accepted by Fracflow.

3.4 Standpipe Installation

Standpipes were installed in three test pits at corner locations (TP1, TP2 and TP4) to establishthe static depth to groundwater, inferred direction of groundwater flow, and to facilitate thecompletion of water-level recovery tests. The standpipes were labelled SP1 (installed in TP1),SP2 (installed in TP2) and SP3 (installed in TP4). Each standpipe was constructed using 1.5 m of0.0508 m diameter, 10 slot monitoring well screen, with a well, point connected to a 1.5 mlength of riser pipe of the same diameter. Each standpipe was constructed and installed at onecorner of the open excavation and held in place with a rod until the excavation was backfilled.

3.5 Hydraulic Conductivity Testing

3.5.1 Undisturbed Soil

The hydraulic conductivity of undisturbed soil was assessed by conducting infiltration testswithin open test pits, and by inspection of the grain-size curves. Infiltration tests were conductedin test pits TP3 and TP5. Commencing from a depth of 1.3 m below ground surface, a hand dughole, having a diameter of between 0.15 m and 0.2 m, was excavated to a depth of 0.25 m belowthe base of the test pit. The hole was filled with clean water and allowed to saturate. The waterlevel was then monitored from a fixed point of reference for 1 to 2 hours. The intent was to usethose data to calculate hydraulic conductivity (K) following standard slug test procedures. Forboth tests, there was no measurable change in the water level.

At test pit TP4, water seepage was encountered near the bottom of the test pit. The rate of inflowwas sufficient to simulate a standard water-level recovery test after forming a hole of uniformdiameter at the base of the test pit with the excavator bucket. Water levels were monitored for



approximately one hour and recorded data were used to estimate K following the method ofBouwer and Rice (Bouwer, 1989).

3.5.2 Disturbed Soil

It was useful to estimate the K values of the disturbed soil, which would represent thepermeability of the soil after backfilling and covering the asbestos waste. At standpipes SP1 andSP2, a disposable bailer was used to develop each well and lower the water level to the base ofthe well screen. Water levels were then measured at an increasing interval time (every 15seconds for the first minute, every 30 seconds until five minutes, every 1 minute until 10minutes, and every 2 minutes until 20 minutes, etc.) until 80 percent recovery occurred or for amaximum of one hour. Those data used to estimate K following the method of Bouwer and Rice(Bouwer, 1989).

Soil permeability was also estimated using a relatively simplistic empirical equation known asHazen’s formula (Fetter, 2001), which is expressed as follows:

K = C × (d10)2 [1]

where, K = hydraulic conductivity (cm/s),C = coefficient (see below), andd10 = grain size corresponding to 10 percent by weight passing.

Values of C are dependent on grain size, with the following ranges:

40 - 80 Very fine sand, poorly sorted40 - 80 Fine sand with appreciable fines80 - 120 Medium sand, well sorted80 - 120 Coarse sand, poorly sorted120 - 150 Coarse sand, well sorted, clean

4.0 RESULTS

4.1 Subsurface Conditions

A detailed description of subsurface conditions encountered at each test pit location is presentedon the test pit logs in Appendix 2. Photographs for each test pit are presented in Appendix 3. Acopy of the sieve report from AGAT is included in Appendix 4. Grain-size distributions and soilclassifications by Fracflow are presented in Appendix 5. The nature of the various materialsencountered in the subsurface is described in separate sections below.

4.1.1 Rootmat and Topsoil

A 0.1 m to 0.3 m thick layer of roots and organic matter was present at all locations, althoughthat material was located beneath a layer of boulders at TP3 and TP5. Incomplete soildevelopment was observed such that the C horizon was absent, as indicated in the previouslyreferenced ARIA report (In Situ, 2018).

4.1.2 Fill

All materials encountered in the test pits were native materials and there was no evidence of anyprevious workings or dumping of fill materials in the area.

4.1.3 Native Till

The test pits were excavated to depths of between 2.59 m and 3.05 m below ground surface.Cobbles and boulders were encountered at all test pit locations. The maximum depth ofexcavation was defined by refusal of the excavator on bedrock or boulders at all locations exceptat TP2 where slumping of the test pit walls forced the premature backfilling of that test pit. Thegenerally dense nature of the till at the other locations formed vertical test pit walls.

The most general classification for soil differentiates between fine-grained and coarse-grainedmaterial. Fine-grained soil is defined as material having greater than 50 percent (by dry weight)


Fracflow Consultants Inc., File 803-44-2

particles equal to or less than 75 µm, while coarse-grained soil is defined as material havinggreater than 50 percent (by dry weight) particles equal to or greater than 75 µm (Atlantic RBCA,2015). Five of the seven samples that were analyzed by AGAT were classified as fine-grained,and the other two samples were considered to be coarse-grained (Appendix 4).

More detailed soil classifications using the Unified Soil Classification System (USCS) and theCanadian Foundation Engineering Manual (CFEM) are presented on the individual grain-sizeanalysis reports that were prepared by Fracflow (Appendix 5). According to the USCS, the soilsranged from SM (Silty Sand with Gravel), SC (Clayey Sand with Gravel), or SC-SM (Silty,Clayey Sand with Gravel); to a SM (Silty Sand), SC (Clayey Sand), or SC-SM (Silty, ClayeySand). Based on the CFEM classification, the till generally consisted of sand, gravelly sand, andsand and gravel, with some to trace silt and clay. The total amount of silt and clay variedbetween 23 and 53 percent of the dry weight of the material. The samples were generally wellgraded based on the shape of the particle-size distribution curves, which is expected to support alow soil permeability. Permeability estimates were made using Hazen’s formula.

The calculation provides an estimate of soil permeability. Others have noted that it is mostreliable for clean sands where d10 ranges between 0.1 and 3 mm (e.g., Holtz et al., 2011).The estimated permeability of the soils, based on the grain-size distributions for the sevensamples tested, ranged between 4.0 × 10-9 m/s and 4.3 × 10-7 m/s (Table A5.1, Appendix 5).

4.1.4 Bedrock

Bedrock (or possibly large boulders) was inferred at depths of between 2.59 m and 3.05 m belowground surface at Test Pits TP1, TP3, TP4 and TP5.

There were no sulphide-bearing materials observed in any of the test pits and the risk ofdeveloping acid-rock drainage conditions is believed to be low.



4.1.5 Groundwater

Zones of groundwater seepage occurred near the bottom of all test pits. The measured depths tostatic groundwater were 2.13 m below ground surface in Standpipe SP1 (at TP1), 1.33 m belowground surface in Standpipe SP2 (at TP2), and 2.06 m below ground surface in Standpipe SP3(at TP4). The inferred direction of groundwater flow is from west to east as illustrated in Figure4.

4.2 Hydraulic Conductivity of Native Till

4.2.1 Undisturbed Till

Infiltration tests were conducted in native, undisturbed soil at Test Pits TP3 and TP5, from adepth of 1.3 m, before the excavations were advanced to refusal. There was no measurabledecline in water level during either of those tests, which from experience suggests that the Kvalues are less than 1 × 10-9 m/s.

A water level recovery test was conducted in TP4 prior to backfilling. Using data from that test,the estimated K value for undisturbed materials at that bottom of that test pit is 3.5 × 10-9 m/s. Acopy of the test report is presented in Appendix 6.

4.2.2 Disturbed Till

Water-level recovery tests were conducted in Standpipe SP1 (at TP1) and in Standpipe SP2 (atTP2). Those data were processed and estimated K values were obtained for disturbed tillsurrounding the well screens at each location. The estimated K value for SP1 was 7.9 × 10-9 m/s.The estimated K value for SP2 was 1.4 × 10-8 m/s. A copy of each test report is presented inAppendix 6.



4.3 Discussion

There are no stated guideline values for minimum K values for in situ soils at an AsbestosDisposal Site, or for soils used for capping materials at such a site. There are also no prescribedseparation distances in regulation between asbestos and water table, or between asbestos andbedrock. Consideration was given to the design requirements specified in the Construction andDemolition Debris Disposal Site Guidelines issued by Nova Scotia Environment (formerly NovaScotia Department of Environment and Labour) (2003). Those guidelines require a minimum of1 m of soil with a hydraulic conductivity of 1 x 10-7 m/s or less between the lowest elevation ofany of the waste materials and the highest elevation of the groundwater or bedrock. That is anunnecessarily onerous requirement for the proposed disposal facility at the MSW ManagementPark, which only accepts bagged, separated asbestos.

In Fracflow’s opinion, both disturbed and undisturbed soils encountered during the current workare suitable for disposal of absestos-containing materials, with the following considerations inmind.

• All vegetation, rootmat, topsoil, and boulders are unsuitable material for hosting andcovering asbestos-containing materials (ACM). Those materials should be removed toexpose competent native undisturbed glacial till.

• The subgrade soil at this site has a significant proportion of fines, varying between23 and 53 percent, is generally well graded and has a low permeability (less than 1 × 10-

7 m/s). Surplus, excavated material that is available after burial of the ACM will also be asuitable capping material. That material will tend to act as an aquitard, potentiallytrapping water near the ground surface, and making it moderately-to-highly susceptible tofrost heave. In order to maintain the integrity of the final cap after closure, the cap willneed to be crowned or sloped to promote drainage toward the perimeter ditches. Theinvert elevation of those ditches should also be below the base elevation of the trenchesthat contain the ACM to help control the water table. The ditches also need to be linedwith well-drained granular materials, such as a Type 2 Gravel as specified in theStandards Specifications of the Nova Scotia Department of Transportation andInfrastructure Renewal (NSTIR).



• The height of the natural water table during wet weather periods has not been establishedwithin the footprint of the planned Asbestos Disposal Cell, but it can be expected to riseto within 1 m of ground surface along eastern portions of that cell during the wet seasons. Water levels will need to be controlled by perimeter drainage around the perimeter of thesite. In addition, the central and western portions of the Asbestos Disposal Cell will bethe preferred areas for mass excavation and waste burial during periods of wet weather(spring and fall) because of the higher ground elevations and deeper water tablecondition.

• Burial of bagged and separated asbestos to within 0.5 m of the bedrock surface isconsidered to be acceptable for this site.

Preface

Fracflow Consultants Inc. is under contract with the Yarmouth County Solid Waste ManagementAuthority to conduct groundwater and surface water monitoring at its waste management park inSouth Ohio. This report documents the scope of work, investigation methods, and results for2017. Sampling locations, event types, parameters and exceedances are summarized below.

Analytical program as per Table 9-2 inYCSWMA's Operations & MaintenanceManual (January 2012). Includesquarterly sampling for general chemistry,metals, BOD, COD and TSS; annualsampling for BTEX/TPH, VOCs andPAHS. Also quarterly sampling formetals, BTEX/TPH, PAHs at SW6 as perOperating Approval 2013-085222-A01.Results compared to CCME FWAL.

Analytical program (except MW15-1,MW15-2) as per Table 9-1 inYCSWMA's Operations & MaintenanceManual (January 2012). Includesquarterly sampling for general chemistry,metals and annual sampling forBTEX/TPH, VOCs and PAHS. MW15-1and MW15-2 also requires BTEX/TPHon a quarterly basis, and VOCs, PAHs,and metals semi-annually as perOperating Approval 2013-085222-A01.Results (excluding colour and turbidity)compared to Canadian Drinking WaterQuality Guidelines.

MW06-1 (Fe, pH)MW06-2 (Fe, Mn, pH)MW06-3 (Fe, Mn, pH)MW06-4 (As, Fe, Mn)MW06-5 (Fe, Mn, pH)MW06-6 (As, Fe, Mn, pH)MW06-7 (Fe, Mn, pH)MW06-8 (Mn, pH)MW15-1 (Fe, Mn, pH)MW15-2 (Mn, pH)

Notes: (1) Trace metals in surface water samples are reported as total metals in unfiltered samples. Trace metals

in groundwater samples are reported as dissolved metals in filtered samples. (2) Colour and turbidity of

groundwater samples are not noted as guideline violations above because the monitoring wells were not designed

and constructed in a manner that would permit development of the filter pack in a manner suitable for potable

use. Any reliance on colour and turbidity data could otherwise be misleading.

1.0 INTRODUCTION

The Yarmouth County Solid Waste Management Authority (YCSWMA) provides wastemanagement services on behalf of the Municipalities of Argyle, Yarmouth and the Town ofYarmouth, in Yarmouth County. The Municipal Solid Waste (MSW) Management Park hosts atransfer facility, a household hazardous waste facility, a Construction and Demolition (C&D)disposal site, an asbestos disposal site, and a contaminated soils remediation facility.

The surface water and groundwater monitoring that is required at this facility, in accordance withvarious Approvals to Operate that were issued by Nova Scotia Environment (NSE), wasconducted by Fracflow Consultants Inc. under contract with YCSWMA. This report presents theresults of the annual 2017 hydrogeological review. Figures, data tables and copies of thelaboratory’s analytical reports are presented in Appendix 1, Appendix 2 and Appendix 3,respectively. The scope of the analytical program is summarized in Appendix 4 and copies ofthe two Aquatic Invertebrate Habitat Assessment reports completed by Envirosphere Consultantsare presented in Appendix 5.

1.1 Site Location and Background

The MSW Management Park is located at 1936 Hardscratch Road, approximately 1 km south ofHighway 340 in South Ohio, Yarmouth County, Nova Scotia. The site is approximately 10 kmnorth of the Town of Yarmouth and approximately 300 km southwest of Halifax (Figure 1). ThePark is also located adjacent to the closed Hardscratch Road MSW facility.

The Management Park initially consisted of the Compost Facility, which was built in themid-late 1990s. The Municipal Solid Waste (MSW) Transfer Station and the C&D DebrisLandfill were added in 2006. The household hazardous waste (HHW) depot, asbestos disposalsite and petroleum-contaminated soils remediation facility (PCSRF) were constructed in 2013.The YCSWMA has operated the C&D Debris Landfill and MSW Transfer Station since 2011when operation was transferred from the Town of Yarmouth. The Town of Yarmouth continuesto operate the Compost Facility and the closed MSW Landfill.

The C&D landfill consists of two cells, with plans for four additional cells to be constructed asneeded. The first cell was built in 2006 and the second was built in 2012. Cell 1 has been closed



and Cell 2 is currently in operation. Water from the C&D landfill is gravity fed to asedimentation pond via a lined ditch. Effluent from the oil-water separator of the contaminatedsoils remediation facility discharges to a lined sedimentation pond at the C&D landfill throughstorm water ditching. This pond is sampled regularly by YCSWMA.

The site has ten groundwater monitoring wells and four surface water monitoring stations thatare the responsibility of the YCSWMA. Additional monitoring of the Compost Facility and theclosed MSW Landfill is conducted by the Town of Yarmouth using another set of monitoringwells and surface water sampling stations.

The surface water and groundwater monitoring program was established in 2006 as part of thebaseline environmental studies that were completed prior to construction of the C&D facility.The monitoring stations have generally been sampled every year on a quarterly basis since 2007as required by Operating Approval 2006-053331-T03 for the C&D site, and Operating Approval2006-053290-T01 for the Transfer Station. A winter sampling event was not conducted in 2015during a transition period when the monitoring contract for the site was being renewed. In 2016,the monitoring program was expanded to include two new wells, MW15-1 and MW15-2, asrequired by Operating Approval No. 2013-085222-A01. The latter two wells were drilledadjacent to the PCSRF in October, 2015.

The following sites were monitored at the MSW Management Park in 2017:

a) Surface water sampling stations (four): SW06-3, SW06-4, SW6 (oil-water separator), andSW5 (sedimentation pond)

b) Ground water stations (ten): MW06-1, MW06-2, MW06-3, MW06-4, MW06-5,MW06-6, MW06-7, MW06-8, MW15-1, MW15-2

1.2 General Scope of Work

The general scope of work consisted of the following activities.

• Measured water levels and determined hydraulic-head elevations at all wells.



• Collected samples of surface water from the designated sampling stations, unless theywere dry. All samples were submitted to Maxxam Analytics for chemical analyses. Ingeneral terms, samples were collected and analyzed for a list of indicator parameters inMarch, May and November, while samples were collected for a list of comprehensiveparameters in August. The detailed scope of the analytical program is outlined inAppendix 4.

• Purged all monitoring wells and monitored field parameters, collected samples andsubmitted those samples to Maxxam Analytics for chemical analyses. In general terms,samples were collected and analyzed for a list of indicator parameters in March, May andNovember, while samples were collected for a list of comprehensive parameters inAugust. The detailed scope of the analytical program is outlined in Appendix 4.

• Compiled all data for presentation in the required format and submitted this report toYCSWMA. Analytical results for groundwater samples were compared with theCanadian Drinking Water Quality Guidelines (CDWG). Analytical results for the surfacewater samples were compared with the guidelines for the protection of FreshwaterAquatic Life (FWAL). The original data tables were prepared by Dillon Consulting andan electronic copy was supplied to Fracflow in 2015 by the YCSWMA. Fracflow hasupdated those tables with the current analytical results in the format provided.

The CCME FWAL guideline value for total phenolics was reported to be 0.004 mg/L in thedatabase generated by the previous consultant and provided to Fracflow by the YCSWMA. It isFracflow’s understanding that the CCME guideline of 0.004 mg/L for phenolics is formonohydric and dihydric phenols only, which is not what is quantified by a Phenols (4-AAP)analysis reported by the laboratory. APHA Standard Methods describe the phenolic compoundsthat are detected by the 4-AAP method as phenol, ortho- and meta-substituted phenols, and,under proper pH conditions, those para-substituted phenols in which the substitution is acarboxyl, halogen, methoxyl, or sulfonic acid group. The 4-AAP (aminoantipyrine) method doesnot determine those para-substituted phenols where the substitution is an alkyl, aryl, nitro,benzoyl, nitroso, or aldehyde group. The phenol guideline has been removed from all summaryanalytical tables for surface water in this report, as well as any previous shading that indicated anexceedance of the 0.004 mg/L value.



2.0 SAMPLING METHODS AND FIELD DATA

Field methods that were used to collect water samples from surface water monitoring stationsand monitoring wells in 2017, along with field-recorded observations and measurements, aredescribed below.

2.1 Surface Water Sampling

Surface water stations SW06-3, SW06-4, SW5 and SW6 were inspected in March, May, Augustand November 2017. The location of each sampling station is shown in Figure 2. Samples werecollected from SW5 during all events. Sampling station SW06-4 was dry in May, August andNovember, and sampling station SW6 was dry in August.

2.1.1 Estimates of Flow

The flow rate of a water course can have a significant bearing on the colour, turbidity andchemical concentrations in surface water. A dilution effect is normally experienced in spring andfall and chemical concentrations tend to increase as baseflow conditions develop in summer andwinter. It is, therefore, important to consider the flow rate at each sampling station. Fracflowprefers to use a flow probe when conditions permit, but a reasonably good estimate can bederived by measuring the width of the stream, depth of water and the time for a floating object totravel a known distance down the stream. Alternatively, a rough approximation of flow can bevisually derived by experienced field staff.

2.1.2 Water Quality Readings

Water quality readings at surface-water sampling stations consisted of temperature, pH, specificconductivity, and dissolved oxygen. All measurements were made using Oakton and HACHhand-held meters. The Oakton and HACH pH meters were calibrated using pH 4.0 and 7.0 buffersolutions, while the Oakton amd HACH conductivity meters were calibrated using a1,413 µS/cm conductivity standard. The response of the HACH dissolved oxygen meter was



tested in an oxygen-saturated solution. All meters recorded water temperature. All field readingsthat were recorded during each sampling event in 2017 are presented in Table 1.

2.1.3 Sample Collection and Handling

All samples of surface water were placed in bottles supplied by Maxxam Analytics for analysisin accordance with the program scope as defined in Appendix 4. The general chemistry samplewas collected in a 200 mL high density polyethylene (HDPE) bottle that was neither filtered norpreserved. Each sample for total dissolved solids (TDS) and total suspended solids (TSS) wascollected in a 500 mL HDPE bottle that was neither filtered nor preserved. Samples for nutrients,chemical oxygen demand and phenolics were each collected in a 100 mL amber glass bottle thatwas preserved using sulphuric acid. Each sample for total metals was collected in a 120 mLHDPE bottle that was preserved with nitric acid, but not filtered. VOC samples were collected inthree 40 mL glass amber bottles that were preserved with sodium bisulphate. Samples formercury analysis were collected in 100 mL amber glass bottles that were preserved withpotassium dichromate. All chemical concentrations are reported as total concentrations by thelaboratory. The sampling technician wore disposable nitrile gloves during sample collection.

The extractable TPH fraction was collected in two 250 mL clear glass bottles preserved withsodium bisulphate. The volatile BTEX fraction was collected in three 40 mL clear glass vialsthat were also preserved with sodium bisulphate. PAHs were collected in two 250 mL clear glassbottles with no preservative added.

All samples were labeled in the field and placed in chilled coolers for transport to the laboratory.A chain-of-custody form was completed and submitted to the laboratory, specifying the chemicalanalyses required.

2.2 Groundwater Sampling

Groundwater samples were collected from each of the ten monitoring wells at the Park in March,May, August and November 2017. The location of each monitoring well is shown in Figure 2.Methods used for measurement of water level, water quality, and for sample collection aredescribed below.



2.2.1 Water Level Measurements

The static water levels in monitoring wells MW06-1 through MW06-8 were measured using aSolinst electronic water-level indicator, prior to purging. The water levels were recorded withreference to the top of the well riser pipes. The height of each riser pipe above ground was alsorecorded. The elevation of the top of each riser pipe was obtained from the existing database,provided by YCSWMA, and the groundwater elevations were calculated accordingly.

The depths to water and the calculated groundwater elevations are presented in Table 2 for allevents in 2017 and for historical measurements that date back to 2006. Water levels recorded inAugust 2017 were contoured to show the inferred directions of local groundwater flow at the site(Figure 3).

2.2.2 Monitoring for Free Product

Groundwater at the Petroleum Contaminated Soils Remediation Facility is required to bemonitored for free phase petroleum hydrocarbons. Fluid levels (oil or water) were measured inMW15-1 and MW15-2 using a Solinst electronic interface probe. The fluid measurements weremade with reference to the top of the well riser pipes. The height of each riser pipe above groundwas also recorded. The elevation of the top of each riser pipe was obtained from the existingdatabase, provided by YCSWMA, and the fluid elevations were calculated accordingly.

The water table in the area of monitoring wells MW15-1 and MW15-2 is close to ground surfaceduring the wet seasons and may exist above the top of the open well screens in spring and fall.Under those conditions, an induced hydraulic gradient will be required prior to an inspection forfree product. The approach used for free product monitoring is described below.

1. Measure the fluid level in the well using an interface probe.2. If there is no product detected, determine if the fluid level is above or below the effective

depth to the top of the open well screen, which is equivalent to the depth of the bottom ofthe protective steel casing. The fluid level will need to be below the base of thatprotective casing, which is 0.4 metres below ground surface at MW15-1 and 0.6 metresbelow ground surface at MW15-2.



3. If the fluid level is above the base of the protective casing, the well will need to bepumped to develop a measurable drawdown in the well and induce an hydraulic gradienttoward the well. That drawdown should be sustained for a period of up to 1 hour in orderfor the drawdown cone to expand beyond the well bore and into the formation. Thepumping time cannot be confidently established until some experience with each well’sresponse to recharge events and pumping has been documented.

4. After pumping, verify that the fluid level is still within the open well screen and thencheck for free product using the interface probe. If free product is detected, confirm thatfinding using a clear plastic bailer.

5. Collect the required groundwater samples for chemical analysis.

2.2.3 Purging

Industry standard normally requires that three standing volumes of groundwater be purged fromeach well before a groundwater sample is collected, in order to consider it representative of thein-situ water quality. Where possible, Fracflow removed approximately three well volumes usingthe dedicated sampling systems. Dedicated WaterraTM inertial pumps were used to develop allwells. Several of the shallow wells went dry before three well volumes could be removed. Forthose situations, the wells were sampled as soon as they recovered an amount sufficient to permitsampling. Table 1 documents the volumes of water removed during each sampling event in2017.

The pH, electrical conductivity, and temperature of the development water were measuredduring the purging cycle using Oakton and HACH hand-held meters. The Oakton and HACH pHmeters were calibrated using pH 4.0 and 7.0 buffer solutions, while the Oakton and HACHconductivity meters were calibrated using a 1,413 :S/cm conductivity standard. Both metersrecorded water temperature. All field readings that were recorded during each sampling event in2017 are presented in Table 1.

2.2.4 Sample Collection and Handling

Groundwater samples were collected using dedicated sampling equipment. Groundwater sampleswere placed in bottles supplied by Maxxam Analytics for analysis in accordance with the



program scope as defined in Appendix 4. Each general chemistry sample was collected in a200 mL high density polyethylene (HDPE) bottle that was neither filtered nor preserved. Eachsample for total dissolved solids (TDS) and total suspended solids (TSS) was collected in a500 mL HDPE bottle that was neither filtered nor preserved. Sample for nutrients and chemicaloxygen demand were each collected in a 100 mL amber glass bottle that was preserved usingsulphuric acid, but not filtered. Each dissolved metals sample was filtered in the field through a0.45 µ disposable filter unit, placed in a 120 mL HDPE bottle and preserved using nitric acid.Samples for mercury analysis were collected in 100 mL amber glass bottles that were preservedwith potassium dichromate. Each sample for dissolved organic carbon was also filtered, placedin a 100 mL HDPE bottle and preserved. VOC samples were collected in three 40 mL glassamber bottles that were preserved.

The extractable TPH fraction was collected in two, 250 mL clear glass bottles preserved withsodium bisulphate. The volatile BTEX fraction was collected in three 40 mL clear glass vialsthat were also preserved with sodium bisulphate. PAHs were collected in two 250 mL clear glassbottles with no preservative added.

The sampling technician wore disposable nitrile gloves during sample collection. The sampleswere stored in a cooler with ice packs and shipped, the next day, to the laboratory with thenecessary chain-of-custody form.



3.0 ANALYTICAL DATA

3.1 Surface Water Quality

The locations of the surface-water monitoring stations are shown in Figure 2. Table 3 containsthe updated analytical results for general chemistry and metals at each of the surface watersampling stations and provides a comparison with historical sampling results. Petroleumhydrocarbon data for surface water samples are presented in Table 4. The results of the PAHanalyses can be found in Table 5, while the VOC results are presented in Table 6. Each tablecompares the surface-water quality to the CCME FWAL guidelines. Appendix 3 contains copiesof the analytical reports issued by the laboratory.

3.2 Groundwater Quality

The locations of each monitoring well are shown in Figure 2. Table 7 contains the updatedanalytical results for general chemistry and metals for groundwater samples and provides acomparison with the previous sampling results. Petroleum hydrocarbon data for groundwatersamples are presented in Table 8. The results of the PAH analyses can be found in Table 9,while the VOC results are presented in Table 10. Each of the tables compare the groundwaterquality data to the CCME CDWQ guidelines. Appendix 3 contains copies of the analyticalreports issued by the laboratory.

The charge balance error (CBE) was exceptionally high for MW06-1 in the May, August andSeptember samples, varying between 21% and 32% as a result of an anion deficiencies. Thereappears to be a positive correlation between CBE and dissolved iron in groundwater at thatlocation. With the notable absence of alkalinity in all samples collected from that well sinceMay 2015, it is possible that the alkalinity is being consumed by iron oxidation during samplestorage and transport to the laboratory. Such mass loss is consistent with the observed aniondeficiency.

Low concentrations of petroleum hydrocarbons have been consistently detected in groundwatersamples from MW06-4, including toluene in the VOC scan, resembling an unidentifiedcompound in the fuel oil range. Concentrations of Modified TPH increased from 0.6 mg/L inOctober 2010, peaked at 1.5 mg/L in November 2013 through October 2014, and have since



declined to 0.41 mg/L in August 2017. Low concentrations of petroleum hydrocarbons, in thefuel oil range, were also detected at MW15-2 in March and August 2017, but there was nodetectable Modified TPH at either of those two wells.

There were no polycyclic aromatic hydrocarbons (PAHs) detected in any of the groundwatersamples that were collected in 2017.



4.0 HYDROGEOLOGICAL ASSESSMENT

Fracflow’s Professional Hydrogeologist completed the Annual Hydrogeological Assessment ofthe Municipal Solid Waste Management Park as required by the existing Operating Approvals.This assessment includes analysis and commentary on water levels, groundwater flow directions,water quality trends, contaminant plume movement, and hydraulic gradients. The ProfessionalHydrogeologist was also involved in all sampling events completed by Fracflow in 2017. Theassessment results are presented below.

4.1 Surface Water

4.1.1 Surface Water Flow

Historical flow data were not available for surface water stations prior to the start of themonitoring contract with Fracflow. Since August 2015, estimates of flow have been recorded atall each stations. Most of those estimates have been visual because the depth to water was tooshallow to permit use of a flow probe and the narrow and irregular shape of the water courses,combined with bottom vegetation, made it impossible to track a floating object for any distance.

Flow rate data for each surface water station are presented in Table 1. Surface water wasdischarging from the sedimentation pond in March and May, at flow rates of 5 Lpm and 10 Lpm,respectively. There was no active flow from the sedimentation pond in August or November.Discharge from the oil-water separator (SW6) varied between 1 Lpm and 2 Lpm, with theexception of a dry condition in August. Active flow was observed at SW06-3 during all foursampling events, varying between 0.5 Lpm and 5 Lpm. The observed flow at SW06-4 occurredonly in March 2017, at a rate of 3 Lpm.

4.1.2 Surface Water Quality

The summary table in the preface of this report, summarizes those surface water samples forwhich parameter concentrations did not meet CCME Freshwater Aquatic Life (FWAL)guidelines in 2017. The sample locations and parameters are listed below.



• SW06-3: Iron, Mercury, and Nickel• SW06-4: Copper and Iron• SW5: Aluminum, Arsenic, Boron , Chromium, and Iron• SW6: Aluminum, Arsenic, Cadmium, Copper, Iron, Lead, and Zinc

Selected indicator parameters, namely alkalinity, chloride, pH and total dissolved solids (TDS),were plotted in Figure 4 to examine the water quality trends at SW06-3. SW06-3 is located atthe southeast corner of the property and trans-gradient of operations at the MSW Park. Theoverall patterns of change in alkalinity, chloride, pH and TDS are indicative of seasonalvariations in precipitation, but weak trends toward decreasing concentrations since 2009 areevident (based on linear regression analysis).

Similar plots were prepared for the other surface water stations. Trends in surface water qualityat SW06-4, which is located down-gradient from the sedimentation pond (SW5), are shown inFigure 5. Alkalinity, chloride, pH and TDS are increasing with time. The water quality trends atthis station show a move toward the quality of water in the sedimentation pond (SW5), partly asthe result of periodic and controlled discharges from that pond, but may also include a baseflowcomponent of groundwater impacted by leachate.

Trends in surface water quality at SW5 are shown in Figure 6, although limited data areavailable. Alkalinity and TDS have decreased with time since peak concentrations were recordedin November 2012. Chloride has remained relatively steady.

Much more limited data (only six data points) are available to trend and discuss changes inmajor-ion concentrations or pH at SW6. However, the trends displayed in Figure 7 do not revealany significant swings in water quality that one would be indicative of a developing impact inthe area of the PCSRF.

4.2 Groundwater

4.2.1 Water Levels and Groundwater Flow Patterns

It is generally accepted that the shape of the water table will tend to mimic the ground surfacecontours, although in a subdued fashion. Based on 1:50,000 scale topographic mapping for the



area, as shown in Figure 1, the inferred direction of ‘regional’ groundwater flow is expected tobe from west to east. Water levels recorded in August 2017 were contoured to show the inferreddirections of local groundwater flow at the site (Figure 3). The average direction of shallowgroundwater flow across the site is also from the west to east. The average horizontal gradientwas approximately 0.035 m/m through the middle of the landfill property. There are no nestedwells at the site and, therefore, the magnitude and direction of the vertical hydraulic gradientscannot be determined.

Current and historical groundwater elevations were plotted for all monitoring wells.Groundwater elevations at MW06-1 and MW06-2 are shown in Figure 8. Groundwaterelevations at MW06-3, MW06-4, MW15-1 and MW15-2 are shown in Figure 9. Groundwaterelevations at MW06-5 and MW06-6 are shown in Figure 10. Groundwater elevations at MW06-7 and MW06-8 are shown in Figure 11. Periods of rising and falling water levels, whichrespectively coincide with wet and dry periods of the year, occur at the same monitoring dates atMW06-1, MW06-2, MW06-3, MW06-4, MW06-5, MW15-1 and MW15-2. That group of sevenwells also exhibits a 0.78 m to 1.43 m difference between the minimum and maximumgroundwater elevations at each location for the period of record.

The patterns of rising and falling water levels at MW06-6, MW06-7 and MW06-8 are notablysubdued relative to the other monitoring wells. Also, with the exception of one anomalously highgroundwater elevation at MW06-7, recorded in October 2008, the differences between theminimum and maximum groundwater elevations at each location exhibited a smaller range ofbetween 0.49 m and 0.79 m. Those three wells are located in the lower part of the flow systemand appear to be influenced by an upward-directed component of vertical groundwater flow.

4.2.2 Water Quality Trends and Plume Movement

Selected indicator parameters, namely alkalinity, chloride, pH and total dissolved solids (TDS),were plotted for all monitoring wells to examine water quality trends (Figure 12 to Figure 21).Trends at MW15-1 (Figure 20) and MW15-2 (Figure 21) are not well established at this timebecause monitoring only began in March 2016.

Monitoring wells that have maintained TDS concentrations below 100 mg/L since wellconstruction in 2006 are MW06-1 (Figure 12), MW06-2 (Figure 13), and MW06-7 (Figure 18).Variations in water quality at each of those well locations are relatively minor and appeared to be



controlled by seasonal changes in groundwater recharge. Waste management activities do notappear to be having any significant impact on groundwater quality at those locations. Locationswhere on-going or historical waste management activities appear to be having some effect ongroundwater quality are at monitoring wells MW06-3, MW06-4, MW06-5, MW06-6 andMW06-8, as discussed in the following paragraphs.

MW06-3 is located on the down-gradient side of the MSW transfer station and HouseholdHazardous Waste Depot. Groundwater quality trends at that location (Figure 14) show a periodof elevated TDS, chloride and low pH in groundwater between June and November 2013 whenTDS increased from a previous baseline value of 48 mg/L to 364 mg/L. Some form of chemicalrelease may have occurred at either the transfer station or the hazardous waste depot in early2013. The TDS and other ion concentrations declined to background values by May 2014 andhave remained relatively low and steady since that date.

MW06-4 is located near the Material Processing/Stockpile Area. Groundwater quality trends atthat location (Figure 15) showed a rapid increase in TDS and alkalinity betweenSeptember 2008 and September 2009. The TDS increased from a baseline value of 117 mg/L tomore than 800 mg/L and alkalinity increased from 59 mg/L to 700 mg/L. It is possible that someform of highly-alkaline chemical release may have occurred at the Material Processing/StockpileArea in 2008, followed by an equally rapid period of attenuation. The TDS and alkalinity haddeclined to 356 mg/L and 270 mg/L, respectively, by March 2011. Since then, the TDS increasedmore slowly to a value of 660 mg/L in October 2014 with concomitant increases in alkalinityand chloride (not as apparent in Figure 15 due to scale; refer to Table 7). That pattern is typicalof an impact from a slowly advancing leachate plume that likely originates from the closedMSW Landfill, located to the immediate southwest. Groundwater elevation and water qualitydata for the closed landfill would need to be reviewed and integrated with this database toconfirm that possibility. The pH has followed a very weak upward trend across the period ofrecord, and the TDS and individual ion concentrations have been in decline since October 2014.

MW06-5 is located at the boundary of the MSW Management Park and due south (trans-gradient) of the C&D Debris Landfill. From 2006 until 2015, variations in groundwater qualityat that location were relatively minor and appeared to be controlled by seasonal changes inrecharge (Figure 16). Between May 2016 and November 2017, TDS and alkalinity increasedsharply from 68 mg/L to 170 mg/L, and from 23 mg/L to 110 mg/L, respectively. Those changescould be indicative of the leading edge of the leachate plume that emanates from the closedMSW landfill.



MW06-6 is located adjacent to, and down-gradient from, the C&D Debris Landfill Site.Groundwater quality trends at that location between 2006 and 2015 (Figure 17) showed largefluctuations in alkalinity, chloride, pH and TDS that probably reflected the various sequences ofmaterial placement, burial and capping of each landfill cell. There was an obvious spike in TDSand sulphate concentrations in March and May 2016 (Figure 17). Sulphate, for example,averaged 11.7 mg/L between 2006 and 2015. Sulphate peaked at 190 mg/L in March 2016 andsince declined to 44 mg/L in November 217. High sulphate has not been a chemical indicator ofsuspected leachate impacts at MW06-4 and MW06-5. Sulphate was usually below the analyticaldetection limit at MW06-4 and averaged only 7.9 mg/L at MW06-5. The high sulphate ingroundwater at MW06-6 is probably associated dissolution of gyproc (CaSO4•2H2O) in the C&DDebris Landfill, but the increased TDS could reflect mixing between sources in the C&D DebrisLandfill with leachate from the closed MSW landfill.

MW06-8 is located on the down-gradient side of the sedimentation pond (SW5). Groundwaterquality trends at that well location (Figure 19) showed a period of rising TDS from an averageof 70 mg/L prior to September 2009, to a peak value of 713 mg/L in March 2012, and then asharp decline to 465 mg/L by August 2012. The TDS values have averaged 283 mg/L sinceNovember 2012. MW06-8 is hydraulically down-gradient from MW06-4. The shape of the timeversus TDS curve and the date when the peak concentration occurred suggests plume migrationfrom the area around MW06-4, where a chemical impact was detected in 2008/2009. Somedegree of chemical reaction and attenuation occurred during subsurface migration, resulting inreduced alkalinity and pH at MW06-8. The dissolved chemical constituents appear to havemigrated approximately 400 metres in 1,100 days for an average velocity of 0.36 metres per day.

There are limited data available to trend groundwater quality at monitoring wells MW15-1 andMW15-2, located adjacent to the Contaminated Soils Remediation Facility. For the purpose ofcompleteness, available data are plotted in Figure 20 and Figure 21, respectively.



5.0 AQUATIC INVERTEBRATE HABITAT ASSESSMENT

Nova Scotia Environment (NSE) requires that YCSWMA conduct an aquatic habitat assessmenton a semi-annual basis to monitor for any impacts of site activities on adjacent watercourses.Envirosphere Consultants Ltd. has provided that service since the fall of 2012.

Two unnamed streams drain the reclaimed landfill site and one stream drains the C&D DebrisLandfill. The aquatic habitats at two sites on one of the streams at the reclaimed landfill site andat two locations draining the C & D Debris Landfill site were assessed on June 12 andOctober 24, 2017. At each location, water quality measurements, observations, and photographsof the biological environment; sediment samples for stream invertebrates; and measurements ofwater quality parameters (temperature, dissolved oxygen, and pH) were taken. Envirosphere’saquatic habitat assessments occurred within a few weeks of Fracflow’s surface water andgroundwater sampling events.

Copies of Envirosphere’s detailed reports are presented in Appendix 5. Overall, the physical siteconditions were found to be acceptable for the maintenance of aquatic life and biologicalcommunities (benthic invertebrates) at the C & D landfill/MSW transfer station site. Stressedconditions were reported at all monitoring stations, but it was Envirosphere’s opinion that thoseconditions were more likely due to seasonal variability (i.e. low flow) than to landfill influences.



6.0 CONCLUSIONS AND RECOMMENDATIONS

The Yarmouth County Solid Waste Management Authority (YCSWMA) provides wastemanagement services on behalf of the Municipalities of Argyle, Yarmouth and the Town ofYarmouth, in Yarmouth County. The Municipal Solid Waste (MSW) management park hosts atransfer facility, a household hazardous waste facility, a C&D disposal site, an asbestos disposalsite, and a contaminated soils remediation facility. Surface water and groundwater monitoring isa condition of various Approvals as issued by Nova Scotia Environment (NSE). FracflowConsultants Inc. is under contract with YCSWMA to conduct the required water qualitymonitoring and this report presents the results of the annual 2017 hydrogeological review. Surface water and groundwater monitoring followed the schedule outlined in Table 9-1(Groundwater) and Table 9-2 (Surface Water) in YCSWMA’s Operations & MaintenanceManual (January 2012), excluding monitoring wells MW15-1 and MW15-2. Groundwaters weresampled quarterly for general chemistry and metals, and annually for BTEX/TPH, VOCs andPAHS. Surface waters were sampled quarterly for general chemistry, metals, BOD, COD andTSS and annually for BTEX/TPH, VOCs and PAHS. The sampling and analytical program formonitoring wells MW15-1 and MW15-2 was conducted pursuant to Operating Approval2013-085222-A01, which required quarterly sampling for BTEX/TPH, and semi-annualsampling for VOCs, PAHs, and metals. The sedimentation pond (SW5) was sampled forBTEX/TPH on a quarterly basis, and effluent from the Petroleum Contaminated SoilsRemediation Facility (SW6) was sampled for metals, BTEX/TPH, and PAHs on a quarterly basisas per Operating Approval 2013-085222-A01.

The summary tables in the preface of this report, list the surface stations where parameterconcentrations did not meet the Freshwater Aquatic Life guidelines (FWAL), and wheregroundwater did not meet the Canadian Drinking Water Quality Limits. The results suggest thatleachate impacts to groundwater quality are developing at MW06-4, MW06-5, and MW06-6.The apparent leachate impacts at MW06-4 and MW06-5 are most likely associated with anadvancing leachate plume from the closed MSW landfill. The apparent leachate impacts atMW06-6 include sources in the C&D Debris Landfill, most notably dissolution of gyproc basedon high sulphate in groundwater, possibly mixed with leachate from the closed MSW Landfill.

Envirosphere completed two aquatic habitat assessments in 2017 and concluded that the physicalsite conditions were acceptable for the maintenance of aquatic life and biological communities(benthic invertebrates) at the C&D landfill/MSW transfer station site. A relevant observation



from Fracflow’s review of work completed in the previous year was that the aquatic assessmentof habitat station IV4, downgradient from the sedimentation pond (SW5), did not occur duringany period when fluids were being actively discharged from that pond. The chemistry of fluid inthe pond was characterized by concentrations of arsenic, boron, copper, iron and zinc that aretypically in excess of the FWAL guidelines (Table 3). It is reasonable to conclude that therelease of that fluid into the aquatic environment will create stress that is attributable to landfillinfluences. The Spring 2017 assessment was conducted during a period of active fluid dischargefrom the sedimentation pond.

The release of fluids from the sedimentation pond should only occur when there is active flow athabitat station IV4 (also known as water quality monitoring station SW06-4). Additionally, therate of release from the pond should be set at roughly one quarter of the natural rate of flow inthe water course immediately prior to release. That target flow rate will create a dilution factorfor boron that will reduce the average concentration of 5.5 µg/L in the pond to the FWALguideline value of 1.5 µg/L. Boron is the metal in the sedimentation pond that tends to be themost elevated above the FWAL guideline.

The proposed schedule for sampling in 2018 is summarized below and detailed in Appendix 4.

Surface Water - General Inorganic and Metals ChemistryLegend Notes

1) The guideline for chloride came into effect in November 2011 and is based on a long-term exposure scenario.

2) The guideline for nitrate of 13 mg-nitrate/L is equivalent to 2.935 mg nitrate-nitrogen/L (CCME Summary Table - updates). The lab reports mg nitrate-nitrogen/L.

3) The guideline for ammonia is dependent on pH and temperature (see factsheet Table 2, FWAL 2010).

4) The guideline for TSS is from NSE standards for a grab sample.

5) The aluminum guideline varies from 0.005 mg/L for pH <6.5 units to 0.1 mg/L for pH >6.5 units.

6) The guideline for boron came into effect December 2009 and is based on long-term exposure.

7) The guideline for cadmium was updated by CCME in January 2014 and is dependent on hardness. Based on a long term exposure scenario, the guideline is 0.04 ug/L for hardness of 0 to <17 mg/L and 0.37 ug/L for hardness >280 mg/L. For hardness between 17 and 280 mg/L, Cd guideline (ug/L) = 10 {0.83 [log (hardness in mg/L)] - 2.46}; see also Table 1, CCME factsheet. Prior to 2014, the guideline for cadmium was calculated as: Cd guideline (ug/L) = 10 {0.86 [log (hardness in mg/L)] - 3.2}. For samples where hardness is not analyzed, the minimum of 0.04 ug/L guideline is used.

8) The guidelines for trivalent and hexavalent chromium are 0.0089 and 0.0010 mg/L, respectively (FWAL 1997). Total chromium is reported by the lab and compared to the more stringent guideline (0.0010 mg/L).

9) The guideline for copper is dependent on hardness: Cu guideline (ug/L) = e0.8545[ln(hardness in mg/L CaCO3)]-1.465 * 0.2, with the minimum guideline being 2 ug/L or 0.002 mg/L. Starting in 2012, copper data will be evaluated in comparison to this calculated guideline. Historically, copper had been evaluated in comparison to a range presented by CCME (i.e., 0.002 to 0.004 mg/L).

10) The guideline for lead is calculated as: Pb guideline (ug/L) = e1.273[ln(hardness in mg/L CaCO3)]-4.705. The guideline varies from 1 ug/L (or 0.001 mg/L) for hardness 0 to 60 mg/L CaCO3 to 7 ug/L (or 0.007 mg/L) for hardness >180 mg/L CaCO3.

11) The guideline for nickel is dependent on hardness: Ni guideline (ug/L) = e0.76[ln(hardness)]+1.06, with the minimum guideline being 25 ug/L or 0.025 mg/L. Starting in 2012, nickel data will be evaluated in comparison to this calculated guideline. Historically, nickel had been evaluated in comparison to a range presented by CCME (i.e., 0.025 to 0.15 mg/L).

12) The guideline for uranium came into effect January 2011 and is based on long-term exposure.

YARMOUTH COUNTY, NOVA SCOTIA –Spring 2017–

for



INTRODUCTION The C & D Debris Landfill/MSW Transfer Station, the adjacent reclaimed landfill site, the compost facility and a petroleum contaminated soils remediation facility1 comprise the Yarmouth County Municipal Solid Waste Park, located on Hardscratch Road near the Town of Yarmouth, Yarmouth County, Nova Scotia. Nova Scotia Environment (NSE) requires the C & D Debris Landfill/Transfer Station to conduct an aquatic habitat assessment semi-annually to monitor impacts of site activities on adjacent watercourses. From 2008-early 2012, the program was carried out by Sprytech Biological Services and Dillon Consulting Ltd. acting on behalf of the proponents. Envirosphere Consultants Ltd. was contracted to continue the monitoring program, with sampling beginning with the fall of 2012, and including spring and fall 2013 to 2017. The results of the spring 2017 sampling period are presented in this report. METHODS Two unnamed streams drain the reclaimed landfill site and one stream drains the new C&D disposal facility. Sampling took place at two sites on one of the streams at the reclaimed landfill site, and at two locations draining the C & D Debris Landfill site. At each location, observations and photographs of the biological environment; sediment samples for stream invertebrates; and measurements of water quality parameters (temperature, dissolved oxygen, and pH) were collected (Figure 1). Biologist, Heather Levy, and Environmental Technician, Joy Baker, of Envirosphere Consultants conducted the sampling on June 12, 2017. Aquatic invertebrates in the streambed at the sites were sampled and identified to the lowest practical taxonomic level, typically to order, family and genus; counts of numbers of each kind, as well as total abundance were determined for each sample. These were used to calculate several indices of benthic community health, which can be compared between sites and with time at each site (an index of community health is like a body mass index or an IQ which gives a single number which can be used to compare individuals or things). Indices calculated are all commonly used in studies of this kind and include: EPT ratio (ratio of abundance of mayflies (Ephemeroptera), caddisflies (Trichoptera), and stoneflies (Plecoptera), to total numbers of organisms); Total



3

Abundance (number of animals in the sample); and Taxon Richness (number of taxa per sample). The four sites were chosen because of their proximity to surface water sampling sites used in the surface water quality-monitoring program at the site. Sites IV1 and IV2 are located on an unnamed tributary running along the northern perimeter of the reclaimed landfill site (Figures 1 and 2). Site IV1 is near water sampling Site SW1. Sites IV3 and IV4 are located on the unnamed stream near the C & D Debris Landfill and petroleum contaminated soils remediation facility; Site IV3 is the upstream site near water sampling Site SW3; and Site IV4 is located downstream, down gradient from the sedimentation pond near SW4 (Figures 1 & 2). Water levels were low, lower than last year2. Sampling and sample processing were consistent with methods used in previous surveys. Each site was sampled with a Surber sampler (30.5 x 30.5 cm). Samples were preserved immediately in 100% isopropanol diluted to approximately 70% with stream water and returned to the lab for sorting of animals from the samples and identification3. Temperature, dissolved oxygen and pH were measured at each site––temperature and oxygen were measured with a YSI Model 85 handheld oxygen meter, and a water sample (200 mL) was taken at each site for pH determination at Envirosphere’s accredited lab (CALA, 2017). Site descriptions included; substrate type, in-stream cover (% shade, % overhang), bank type and stability, depth and width. Photographs of the stream were taken looking upstream and downstream at each site, and a photo of the substrate was taken at all locations. SITE DESCRIPTIONS Site IV1 Site IV1 is located on an unnamed stream, downstream of the reclaimed landfill (the old landfill has been capped and a compost curing area is located there). The sampling site, as sampled in June 2017, is the same as the previous years, a slow run having a bottom substrate of mainly sand and minor amounts of gravel and cobble as well as fines. Orange iron flocculates periodically observed in previous surveys were again observed this sampling period. The stream channel is approximately 30% shaded by a mixed coniferous/deciduous (fir and maple) canopy. There is minimal overhanging vegetation (nearly absent, < 1%) and occasional vegetation in the streambed as well as moderate amounts of detritus, tree leaves and woody debris. Banks are mainly stable with minimal undercutting and covered in mosses, sedges, grasses, ferns and occasional shrubs; slope approaches are low. The wet width was 1 m and the average depth 5.7 cm. Water temperature was 19.3 oC; dissolved oxygen (DO) was low/moderate 5.3 mg/L, with 57.2 % saturation; pH was 7.4 (Table 1). Site photos are presented in Appendix 1. 2 Site IV2 was almost dry, so sampling occurred 5-6 m downstream of original site as was done in the 2014, 2015 and 2016 sampling periods. 3 Samples were washed over an 0.5 mm mesh sieve to remove fine particles (mud etc.) and animals were removed from the samples by a technician using a stereo microscope and identified to the lowest convenient taxonomic level (typically to family) using available taxonomic literature. A list of taxonomic references used is found in Appendix 3.

Site IV2 Site IV2 is located along the northern perimeter of the reclaimed landfill and is ~1.5 m downstream of an outflow from a large pond; upstream portions of the stream originate above Hardscratch Road. The original sampling site was almost dry, as in 2013 - 2016 (water levels were low at the site and it was difficult to find a good sampling location) so samples were taken 5 – 6 m downstream. Bottom substrate was gravelly sand with fines and occasional cobble as well as in-stream detritus, tree leaves and woody debris. The stream channel is 75% shaded by a mixed coniferous/deciduous (spruce, larch, alder, birch and maple) canopy. Flow was minimal and there was negligible overhanging vegetation (nearly absent) present. Banks were low and vegetated with moss, ferns, flowering plants and grasses. The wet width was approximately 0.5 m, having a mid-channel depth of 8 cm. Water temperature was 18.0 oC; DO was low/moderate at 4.1 mg/L, with 43.3 % saturation; and pH was 5.6 (Table 1). Site photos are presented in Appendix 1. Site IV3 Site IV3 is located just upstream of Surface Water Site 3 (SW3) along the unnamed tributary near the new C & D Debris Landfill site. The stream crosses a cut line4 prior to flowing downstream toward a deep pool and then further to Site IV4. The site is a run located to the side of a cut line, and has a bottom substrate of gravelly sand with mud and occasional cobble and boulder. The stream channel is slightly shaded (5%) by overhanging vegetation, primarily by grasses and sedges. Riparian areas upstream are forested with a mix of coniferous/deciduous (maple) trees. Blowdowns were noted in the area as in previous sampling periods. Water levels in the system were higher than last year; and in-stream woody debris, occasional tree leaf and detritus, were observed. Banks were very low (non-existent in places particularly along the cut line) resulting in the water spreading out and filling in the ruts of the cut line. The wet width was about 0.75 m, having an average depth of 5.8 cm. Water temperature was 16.1 oC; DO was low/moderate at 5.4 mg/L, with 54.8 % saturation; and pH was 6.6 (Table 1). Site photos are presented in Appendix 1. Site IV4 Site IV4 is located downstream of Site IV3, east and down gradient of a sedimentation pond and close to surface water Site 4 (SW4). Water levels and flow were low to moderate. Sampling was conducted in a run approximately 2.7 m wide and 5.7 cm deep with a substrate of sandy gravel, cobble and boulder. There was some exposed in-stream vegetation on boulders; and in-stream woody debris, detritus and tree leaves occurred. The stream channel was ~75% shaded by a mixed canopy of coniferous/deciduous (fir/maple/spruce/larch) trees. Slope approaches were low, and banks were mainly stable and vegetated with moss, ferns, tree seedlings and covered in fallen tree leaves from last



5

year as well as woody debris. Water temperature was 13.9 oC; DO was low/moderate at 5.1 mg/L, with 49.8 % saturation; and pH was 6.7 (Table 1). Site photos are presented in Appendix 1. INTERPRETATION Water Quality Measurements

Temperatures at all sites were warm (13.9 – 19.3 ºC), and characteristic of the season, warmest at Site IV1 and lowest at Site IV4 (Table 1). Dissolved oxygen levels were low/moderate (4.1 – 5.4 mg/L) (Table 1); lowest at site IV2 (Table 1). Acidity (pH) ranged from below neutral to slightly above neutral (5.6 – 7. 4), with the most acidic conditions (i.e. 5.6) occurring at the upstream site, IV25. Benthic Invertebrate Communities

Sites on the unnamed tributary within the reclaimed landfill site (Sites IV1 and IV2) had low moderate abundance and diversity of stream invertebrates—825 and 3,443 individuals/m2, and 8 and 11 taxa, respectively (Table 2), with abundance higher at Site IV2—largely due to high numbers of oligochaetes, although minor amounts of other species (i.e. aquatic beetles, water mites (Hydrachnidia), crustaceans (copepods and the isopod, Caecidotea sp.), midge fly larvae (Chironomidae), etc.) were also present. Abundance at Site IV1 is attributed mainly to the presence of oligochaetes, crustaceans (copepods and the isopod, Caecidotea sp.), as well as smaller numbers of midge fly larvae, water mites and springtails (Collembola)(Table 2). EPT ratios, which indicate high water quality associated with the presence of certain invertebrate taxa, was zero at both sites (i.e. none of the EPT species were present). The zero EPT taxa and high numbers of oligochaetes at both sites is indicative of stressed conditions, likely due to seasonal variability. Sites along the tributary within the active C & D Debris Landfill site (Sites IV3 & IV4) had moderate abundance (1045 – 2596 individuals/m2, respectively) and moderate to low diversity (13 and 5 taxa, respectively) (Table 2). Oligochaetes, crustaceans (i.e. copepods), midge fly larvae and hydrachnidia (water mites) contributed to the abundance at both sites; aquatic beetles and mollusks (bivalves belonging to the sphaeriidae family) were also present at Site IV3, but in lower numbers; plecoptera (stoneflies) were present at Site IV4 only (Table 2). Site IV3 had a zero % EPT ratio and Site IV4 had a low % EPT ratio (4.2%). The moderate diversity at Site IV3 and the presence of plecoptera at Site IV4 indicates acceptable water quality for benthic organisms. Comparison of 2017 vs Previous Monitoring EPT ratios this year were lower than 2016 spring samples at sites IV1 and IV3, comparable at Site IV2 and higher than 2016 values, at Site IV4 (Figures 3 & 4). 5 In spring of 2013, 2014, 2015, 2016 the pH value at this site was 5.5, 5.4, 5.4 and 5.7, respectively.

CONCLUSIONS AND RECOMMENDATIONS Overall, physical conditions were acceptable for the maintenance of aquatic life and biological communities (benthic invertebrates) at the C & D landfill/MSW transfer station site. pH was above or at the guideline level of 6.5 at all sites, with the exception of Site IV2, which at 5.6 was well below the guideline. DO was below the Freshwater Aquatic Life Guidelines (CCME 1999)6 at all sites. Despite chemical findings, however, benthic organisms typically undergo short-term changes or variations in abundance between sampling periods (during the year and between years) and the variability observed is consistent with natural variation. Abundance was highest at Site IV2 and lowest at Site IV1 and taxon richness was highest at Site IV3 and lowest at Site IV4 (5 taxa). Stressed conditions (dominance by a small number of individual groups (e.g. chironomids (midge fly larvae), oligochaetes and/or crustaceans) and low EPT% ratio) occurred at all sites, though moreso at sites IV1 and IV2. These conditions, though, are more likely due to seasonal variability (i.e. low flow) than to landfill influences. The presence of groups of ‘pollution sensitive’ organisms such as plecoptera and mollusks and/or crustaceans (e.g. isopods and copepods) is indicative of acceptable water quality for benthic organisms. Crustaceans were present at all sites, mollusks at one of the four sites and plecoptera present at one site, which indicates suitable benthic invertebrate habitat. As noted in earlier reports, it is important to put stream protection measures in place along the cut line and the trail to groundwater monitoring wells adjacent to Site IV3 in order to prevent entry of equipment or personnel into the stream. The invertebrate assessments continue to provide useful information on conditions in the tributaries receiving flow from the reclaimed landfill or C & D debris landfill/MSW transfer site. Based on the monitoring requirements for the sites, the next invertebrate sampling event will be in the fall of 2017.

INTRODUCTION The C & D Debris Landfill/MSW Transfer Station, the adjacent reclaimed landfill site, the compost facility and a petroleum contaminated soils remediation facility1 comprise the Yarmouth County Municipal Solid Waste Park, located on Hardscratch Road near the Town of Yarmouth, Yarmouth County, Nova Scotia. Nova Scotia Environment (NSE) requires the C & D Debris Landfill/Transfer Station to conduct an aquatic habitat assessment semi-annually to monitor impacts of site activities on adjacent watercourses. From 2008-early 2012, the program was carried out by Sprytech Biological Services and Dillon Consulting Ltd. acting on behalf of the proponents. Envirosphere Consultants Ltd. was contracted to continue the monitoring program, with sampling beginning with the fall of 2012, and including spring and fall 2013 to 2017. The results of the fall 2017 sampling period are presented in this report. METHODS Two unnamed streams drain the reclaimed landfill site and one stream drains the new C & D disposal facility. Sampling took place at two sites on one of the streams at the reclaimed landfill site, and at two locations draining the C & D Debris Landfill site. At each location, observations and photographs of the biological environment; sediment samples for stream invertebrates; and measurements of water quality parameters (temperature, dissolved oxygen, and pH) were collected (Figure 1). Biologist, Heather Levy, and Environmental Technician, Joy Baker, of Envirosphere Consultants conducted the sampling on October 24, 2017. Aquatic invertebrates in the streambed at the sites were sampled and identified to the lowest practical taxonomic level, typically to order, family and genus. Taxonomic groups were enumerated and total abundance determined for each sample. These were used to calculate several indices of benthic community health, which can be compared between sites and, over time, at each site (an index of community health is like a body mass index or an IQ which gives a single number which can be used to compare individuals or things). Indices calculated are all commonly used in studies of this kind and include: EPT ratio (ratio of abundance of mayflies (Ephemeroptera), caddisflies (Trichoptera), and stoneflies (Plecoptera), to total numbers of organisms); Total Abundance (number of animals in the sample); and Taxon Richness (number of taxa per sample).

The four sites were chosen because of their proximity to surface water sampling sites used in the surface water quality-monitoring program at the site. Sites IV1 and IV2 are located on an unnamed tributary running along the northern perimeter of the reclaimed landfill site (Figures 1 and 2). Site IV1 is near water sampling Site SW1. Sites IV3 and IV4 are located on the unnamed stream near the C & D Debris Landfill and petroleum contaminated soils remediation facility; Site IV3 is the upstream site near water sampling Site SW3; and Site IV4 is located downstream, down gradient from the sedimentation pond near SW4 (Figures 1 & 2). Water levels were comparable to last year2. Sampling and sample processing were consistent with methods used in previous surveys. Each site was sampled with a Surber sampler (30.5 x 30.5 cm). Samples were preserved immediately in 100% isopropanol diluted to approximately 70% with stream water and returned to the lab for sorting of animals from the samples and identification3. Temperature, dissolved oxygen and pH were measured at each site––temperature and oxygen were measured with a YSI Model 85 handheld oxygen meter, and a water sample (200 mL) was taken at each site for pH determination at Envirosphere’s accredited lab (CALA, 2017). Site descriptions included; substrate type, in-stream cover (% shade, % overhang), bank type and stability, depth and width. Photographs of the stream were taken looking upstream and downstream at each site, and a photo of the substrate was taken at all locations. SITE DESCRIPTIONS Site IV1 Site IV1 is located on an unnamed stream, downstream of the reclaimed landfill (the old landfill has been capped and a compost curing area is located there). The sampling site, as sampled in October 2017, is the same as the previous years, a slow run having a bottom substrate of mainly sand and minor amounts of gravel and cobble as well as fines. Orange iron flocculates were observed upstream of the sampling site on the bottom substrate as they were during other fall surveys (2013-2016). The stream channel is approximately 40% shaded by a mixed coniferous/deciduous (primarily fir and maple) canopy. There is minimal overhanging vegetation (nearly absent, < 1%) and occasional vegetation in the streambed as well as moderate amounts of detritus, tree leaves and woody debris. Banks are mainly stable with minimal undercutting and covered in mosses, sedges, grasses, ferns and occasional shrubs; slope approaches are low. The wet width was 0.75 m and the average depth 3.3 cm. Water temperature was 13.8 oC; dissolved oxygen (DO) was low 2.9 mg/L, with 27.8 % saturation; pH was 6.9 (Table 1). Site photos are presented in Appendix 1.

2 Site IV2 was almost dry, so sampling occurred 5-6 m downstream of original site as was done in 2014-2016. 3 Samples were washed over an 0.5 mm mesh sieve to remove fine particles (mud etc.) and animals were removed from the samples by a technician using a stereo microscope and identified to the lowest convenient taxonomic level (typically to family) using available taxonomic literature. A list of taxonomic references used is found in Appendix 3.

Site IV2 Site IV2 is located along the northern perimeter of the reclaimed landfill and is ~1.5 m downstream of an outflow from a large pond; upstream portions of the stream originate above Hardscratch Road. The normal sampling site was almost dry, as in 2014-2016 (water levels were low at the site and it was difficult to find a good sampling location) so samples were taken 5 – 6 m downstream. Bottom substrate was gravelly sand with fines and occasional cobble as well as in-stream detritus, tree leaves and woody debris. The stream channel is 40% shaded by a mixed coniferous/deciduous (spruce, larch, alder, birch and maple) canopy. Flow was minimal and there was negligible overhanging vegetation (nearly absent) present. Banks were low and vegetated with moss, ferns, flowering plants (i.e. aster) and grasses. The wet width was approximately 0.5 m, having a mid-channel depth of 7 cm. Water temperature was 15.2 oC; DO was low at 1.2 mg/L, with 12.2 % saturation; and pH was 5.7 (Table 1). Site photos are presented in Appendix 1. Site IV3 Site IV3 is located just upstream of Surface Water Site 3 (SW3) along the unnamed tributary near the new C & D Debris Landfill site. The stream crosses a cut line4 prior to flowing downstream toward a deep pool and then further to Site IV4. The site is a run located to the side of a cut line, and has a bottom substrate of gravelly sand with mud and occasional cobble and boulder. The stream channel is slightly shaded (15 %) by overhanging vegetation, primarily by grasses and sedges. Riparian areas upstream are forested with a mix of coniferous/deciduous (maple) trees. Blowdowns were noted in the area as in previous sampling periods. Water levels in the system were low and flow was minimal; and in-stream woody debris, occasional tree leaf and detritus, were observed. Banks were very low (non-existent in places particularly along the cut line) resulting in the water spreading out and filling in the ruts of the cut line. The wet width was about 0.75 m, having an average depth of 4.7 cm. Water temperature was 13.0 oC; DO was low at 3.3 mg/L, with 31.4 % saturation; and pH was 6.6 (Table 1). Site photos are presented in Appendix 1. Site IV4 Site IV4 is located downstream of Site IV3, east and down gradient of a sedimentation pond and close to surface water Site 4 (SW4). Water levels and flow were low. Sampling was conducted in a slow run approximately 2 m wide and 2.3 cm deep with a substrate of sandy gravel, cobble and boulder. There was some exposed in-stream vegetation on boulders; and in-stream woody debris, detritus and tree leaves occurred. The stream channel was about 40 % shaded by a mixed canopy of coniferous/deciduous (fir/maple/spruce/larch) trees. Slope approaches were low, and banks were mainly stable and vegetated with moss, ferns, tree seedlings and covered in fallen tree leaves and



5

woody debris. Water temperature was 12.8 oC; DO was low at 2.2 mg/L, with 20.2 % saturation; and pH was 6.3 (Table 1). Site photos are presented in Appendix 1. INTERPRETATION Water Quality Measurements Temperatures at all sites were warm (12.8 – 15.2 ºC), and characteristic of the season, warmest at Site IV2 and lowest at Site IV4 (Table 1). Dissolved oxygen levels were low (1.2 – 3.3 mg/L) (Table 1); lowest at site IV2 (Table 1). Acidity (pH) ranged from 5.7 – 6.9, all below neutral, with the most acidic conditions (i.e. 5.7) occurring at the upstream site, IV25. Benthic Invertebrate Communities Sites on the unnamed tributary within the reclaimed landfill site (Sites IV1 and IV2) had moderate to low abundance and diversity of stream invertebrates—4,202 and 781 individuals/m2, and 8 and 4 taxa, respectively (Table 2). Abundance at Site IV1 was largely due to high numbers of oligochaetes, although minor amounts of other species (e.g. alderflies/dobsonflies/fishflies (Megaloptera), crustaceans (copepods and the isopod, Caecidotea sp.), midge fly larvae (Chironomidae) and caddisfly larvae (Trichoptera)) were also present. Abundance at Site IV2 is attributed mainly to the presence of oligochaetes, as well as smaller numbers of dipterans (biting and non-biting midge fly and phantom crane fly larvae (Ptychopteridae)(Table 2). EPT ratios, which indicate suitable water quality associated with the presence of certain invertebrate taxa, was zero at Site IV2 (i.e. none of the EPT species were present) and low at Site IV1. The zero and negligible EPT taxa and high numbers of oligochaetes at both sites are indicative of stressed conditions, such as due to seasonal variability. Sites along the tributary within the active C & D Debris Landfill site (Sites IV3 & IV4) had low abundance (561 – 1661 individuals/m2, respectively) and moderate diversity (9 and 10 taxa, respectively) (Table 2). Oligochaetes, crustaceans (i.e. copepods and/or the isopod, Caecidotea sp), midge fly larvae, caddisfly larvae and mollusks (bivalves at Site IV3 and gastropods at Site IV4) contributed to the abundance at both sites; aquatic stonefly larvae (Plecoptera) and leeches (Hirudinea) were also present at Site IV4, but in lower numbers (Table 2). Sites IV3 and IV4 had low EPT ratios (3.9 and 7.9%, respectively). The moderate diversity at sites IV3 and IV4, the presence of caddisfly larvae at both sites and stonefly larvae at Site IV4 indicates acceptable water quality for benthic organisms. Comparison of 2017 vs Previous Monitoring EPT ratios this year were lower than 2016 fall samples at sites IV1 and IV3, zero at Site IV2 in both years and higher than 2016 values, at Site IV4 (Figures 3 & 4).

5 In fall of 2013, 2014, 2015 and 2016, the pH value at this site was 5.6, 6.0, 5.3 and 4.7, respectively.

CONCLUSIONS AND RECOMMENDATIONS Overall, physical conditions were acceptable for the maintenance of aquatic life and biological communities (benthic invertebrates) at the C & D landfill/MSW transfer station site. pH was above or at the guideline level of 6.5 at two sites; slightly below at Site IV4; and at Site IV2, well below the guideline at 5.7. DO was below the Freshwater Aquatic Life Guidelines (CCME 1999)6 at all sites. Despite chemical findings, however, benthic organisms typically undergo short-term changes or variations in abundance between sampling periods (during the year and between years) and the variability observed is consistent with natural variation. Abundance was highest at Site IV1 and lowest at Site IV3 and taxon richness was highest at Site IV4 and lowest at Site IV2 (4 taxa). Stressed conditions (dominance by a small number of individual groups (e.g. oligochaetes, chironomids (midge fly larvae), and/or crustaceans) and low EPT% ratio) occurred at all sites, though moreso at sites IV1 and IV2. These conditions, though, are more likely due to seasonal variability (i.e. low flow) than to landfill influences. The presence of groups of ‘pollution sensitive’ organisms such as Plecoptera, Trichoptera and mollusks and/or crustaceans (e.g. isopods and copepods) is indicative of acceptable water quality for benthic organisms. Crustaceans and Trichoptera were present at three of the four sites, mollusks at two sites and Plecoptera present at one site, which indicates suitable benthic invertebrate habitat. As noted in earlier reports, it is important to put stream protection measures in place along the cut line and the trail to groundwater monitoring wells adjacent to Site IV3 in order to prevent entry of equipment or personnel into the stream. The invertebrate assessments continue to provide useful information on conditions in the tributaries receiving flow from the reclaimed landfill or C & D debris landfill/MSW transfer site. Based on the monitoring requirements for the sites, the next invertebrate sampling event will be in the spring of 2018.
