5. Historical and Background InformationDescribe briefly what you know about the site that is relevant to sampling and analysis for this investigation.

The sites included in this work plan are locations where the EPA is conducting PreliminaryAssessments (PA) in response to petitions that were submitted by a number of people concerned overmultiple occurrences of osteosarcoma (a rare form of bone cancer) in the West Salem area of Oregon.The properties listed above were selected for inclusion in the PA during discussions that took placebetween the EPA, parents of the children who contracted osteosarcoma, and other interested parties;and were all identified as areas where the children had frequented. To date, no clear causal link hasbeen identified between these incidences of osteosarcoma and environmental factors or exposures.

Acknowledging the complex, multivariate nature of cancer risk and onset, and that this assessment isnot intended to represent an epidemiological study, review of available literature suggests that


4/28

exposure to radium may result in an elevated risk profile for osteosarcoma. The most common radiumisotope (Radium 226) decays by alpha particle emission with accompanying gamma radiation.

Although the linkage appears more tenuous, other theories suggest a positive correlation may existbetween exposure to radon gas and osteosarcoma. While there are no known sources of radium inthe West Salem study area, indoor radon concentrations for West Salem are among the highestdocumented in Oregon.

At present, all of the properties included designated for these PAs are currently developed whetherwith structures or for recreational use. In general, prior to these developments, much of the WestSalem area was cultivated orchard land. While the specific pesticides, fertilizers, or other materialsused at these orchard areas is not currently known, based on conversations with local citizens, lead-arsenate may have been used in the area, though its use was not widespread. Other pesticidestypically used at orchards in the area have reportedly contained copper and sulfur.

The City of Salem obtains drinking water from a surface water source (North Santiam River) locatedapproximately 18-miles southeast and upgradient of the properties included in this PA. That water isprovided/made available to more than 177,000 customers. In accordance with the EPAs SafeDrinking Water Act (SDWA), the City of Salem actively monitors drinking water quality. Parameterstested for include inorganic, microbiological, radioactive, and other disinfection (i.e., chlorination)related constituents. During this testing, the water district collects samples from the Geren IslandTreatment Facility, the water distribution network, and from end user (i.e., taps) locations. Accordingto the 2012 water quality report, none of the parameters tested for were present at concentrations inexcess of the EPAs published SDWA Maximum Contaminant Levels (MCLs). With respect to the

radiologic testing, a ground water sample was collected from the one backup well located in theWest Salem area and tested for the presence of radium. Radium levels in this well were 0.26-picocuries per liter (pCi/L), well below the EPAs MCL of 5-pCi/L. It should also be noted that althoughthis well is tied into the water districts system, as the previously mentioned surface water sourceprovides ample supply, the well is not used. In addition, while the City also operates an undergroundaquifer storage and recharge system; the design and construction of the distribution network (i.e.connection locations, hydraulic gradients) essentially prevent water from the aquifer storage systembeing provided to individuals within the West Salem study area. Private drinking water wells havebeen documented in the West Salem area, and are expected to provide drinking water to a verylimited number of residences.

As previously mentioned, indoor radon levels in the Salem area have been documented to beamongst the highest in the state of Oregon. More specific to the two schools included in these

assessments (Walker Middle School and West Salem High School), the Salem School Districtimplemented a radon screening protocol, beginning in 2001. This screening involved placing a radontest kit in an interpreted worst case location within individual schools. Following on from thatscreening, entire school buildings were then sampled, focusing first on locations where radon wasdetected, then other nearby buildings and facilities.

In January of 2013, more extensive radon testing was performed at Walker Middle School and WestSalem High School. Testing included deployment of 44 radon test kits at Walker Middle School and92 test kits at West Salem High. All of the radon test kits were placed in rooms that were in contactwith or below the ground surface. For Walker Middle School, testing revealed the highest radon levelto be 1-pCi/L of air, below the 4 pCi/L action level established by the EPA. For West Salem High, withtwo exceptions radon levels were typically less than 2.0-pCi/L of air again, below the EPA establishedradon action level. The two exceptions were two lower level classrooms (Room B105B at 5.8-pCi/L

and B117 at 4.9-pCi/L). In response, school maintenance personnel have worked to better sealcracks and trench plates in the floors and adjust the air supply to increase air circulation in the roomssuch that both rooms are under positive pressure. These measures have been followed bycontinued radon monitoring. This monitoring has documented radon level exceedances, and to theSTARTs knowledge work is ongoing.

A search of environmental database listing for the sites in the vicinity of the properties included in thisPA revealed numerous listings, the majority of which are located in the industrial/commercial area inthe vicinity of the Walker Middle School, 7

thand Patterson, and Wallace Marine Park locations.

Releases and contamination issues documented in this area are not considered to representconditions significantly different than what may be encountered in most any industrially developedarea. These listings generally consist of releases of various petroleum products, solvents, and heavy


5/28

Page 4 of 17

metals. While both Walker Middle School and Hanard Machine were listed in these databases, theselistings were related to releases discovered during removal of underground storage tanks (USTs) thathad stored petroleum products. As a result of chlorine cylinder leaks at the onsite pool, Walker Middleschool was also listed as a HAZMAT site. Database listings in residential areas were generallyrelated to heating oil tank removals.

Gould Battery/GNB was also listed in the database report in relation to a petroleum release, and aspill(s) of lead oxide; after participating in the Oregons Voluntary Cleanup Program and filing anenvironmental covenant that limits use of that site to industrial purposes, the GNB site was granted aNo Further Action status.More specific information on current and historic use and development of the five separate sitesincluded in this PA is provided below.

Walker Middle School (Figures 2 and 3): This site includes six tax lots developed with the middleschool buildings, an assortment of athletic playfields, and vehicular infrastructure including drivewaysand parking lots. A city operated swimming pool is also located on the property; however the pool hasbeen closed in the recent past as a result of city budget shortfalls. Based on a review of historic aerialphotos, assessor records, and discussions with site knowledgeable individuals, the school was firstconstructed in the late 1950s/early 1960s and underwent a major expansion in the mid-1990s. Priorto construction of the school, a 1955 dated aerial photo depicts the school site as a cleared andpredominantly grass covered lot, with an east-west oriented running track visible on the west side ofthe property, several smaller access drives on the central and northwest corner of the site, and severalsmaller buildings constructed on the site. Details regarding construction or use of those smaller

structures were not readily available. An earlier plat map of the site drawn prior to constructiondepicted a drainage ditch crossing the site from east to west.

Current site conditions are considered typical for public school buildings; concrete block bearing andexterior walls define the majority of the structure, with a slab-on-grade foundation, a central boiler thatsupplies hot-water/steam for convective heat, and interior finishes consisting of gypsum board,cellulose ceiling panels, vinyl floor tiles, and carpet. The school has wood shop and scienceclassrooms, but not automotive or metal working spaces. The two laboratory science classroomsinclude a front desk/table with running water and natural gas, and non-reactive countertops.Chemicals are stored in a room located between the two classrooms. As classes were in session, thisroom was not accessed during a recent site visit.

Exterior areas at the school were primarily grass-covered, with asphalt drives and parking areas, and

landscaping at near-building locations. The site is a generally flat alluvial plain; a steep embankmentabuts the northern margin of the site, and is interpreted to locally coincide with the northern limits ofthe Willamette Rivers historic meanders. Surface water drainage is handled by storm-sewercatchments observed in the paved areas across the site. A small fence-enclosed, and apparentlyman-made, wetland is located on the north side of the property. The Willamette River is locatedapproximately one-half of a mile to the south/southeast.

Surrounding property is predominantly residential, with single- and multi-family dwellings constructednorth, south, and west of the site. Industrial/commercial development is located to the east/southeast.The nearest businesses include a boat storage/repair company; a transmission repair shop; andHanard Machine which provides precision machining work. An additional machine shop, and a steelsales and processing business are located further to the southeast. Until the mid- to late-1990s,Gould Battery had been located on the south side of the steel business.

7th

and Patterson Ballfields (Figure 2 and 4): This ballfield site is a portion of a single tax parcelthat has been owned and occupied by Hanard Machine since 1995. Although there is no record ofprior development in the locations occupied by the ballfields, the lot as a whole includes threebuildings that were constructed sometime between 1936 and 1950. Over time, the nearest of thesebuildings has expanded westward, and now abuts the eastern edge of the ballfield area. A 1936dated aerial photo shows the entire Hanard Machine property cleared and covered with low-vegetation. The 1950 dated aerial photograph depicts what appears to be a baseball diamond at thelocation of the current ballfields, and the eastern-most portion of the building currently occupied byHanard Machine.

Prior to Hanard Machines 1995 acquisition of the property, this site had been owned and occupied by


6/28

Page 5 of 17

Asten-Hill. According to a representative of Hanard Machine, Asten-Hill, now Asten-Johnson, hadmanufactured textile products such as dryer-sheets for use by the pulp/paper production business.While the exact process or materials used at the Salem location is not currently known, based on legalproceedings against other Asten-Hill dryer-sheet manufacturing locations, asbestos can be associatedwith the manufacture of these dryer-sheets. Earlier Sanborn Fire Insurance Maps show the propertyoccupied by a felt manufacturing business (1978) and a flax textile business (1950). Again, littledetail is currently available with regard to the processes, resources used, or potential contaminantsthat may have been associated with these businesses.

At the time of the site reconnaissance, the ballfields were fence enclosed, predominantly grasscovered, with exposed soils only present in baseball diamond infield areas. No disturbed vegetation,odors, or other similar conditions were noted during site review.

The site and immediate vicinity is a generally flat alluvial plain; a steep embankment is located severalhundred feet to the north, and is interpreted to locally coincide with the northern limits of theWillamette Rivers historic meanders. Surface water drainage is handled by storm-sewer catchmentsobserved in the roadways bracketing the site. The Willamette River is located approximately one-halfof a mile to the south/southeast. When necessary, the ballfields are irrigated with city water. No hosebibs or drinking water fountains are provided at the ballfield.

Nearby land surrounding the property is used for both residential and industrial purposes, with single-and multi-family dwellings constructed to the west; and industrial/commercial development to theimmediately north, east, and south. The nearest businesses include a boat storage/repair company

and a transmission repair shop, both to the north; and a machine shop and a steel sales andprocessing business to the south. Until the mid- to late-1990s, Gould Battery had been located on thesouth side of the steel business.

Hanard Machines facilities directly east of the site provide precision machining work for a variety ofmanufacturing uses According to company representatives, machining work involves turning, lathing,and/machining of metals delivered to the shop. No foundry, smelting, or other extractive refining workis performed onsite.

Wallace Marine Park (Figure 5): During community meetings, attendees discussed concernsregarding potential exposure risks at Wallace Marine Park. Wallace Marine Park occupies nineseparate tax lots and approximately 101 acres of land along the western bank of the Willamette River.While a reconnaissance of the park did not occur in conjunction with visual reviews of other sites,

based on a review of aerial photos and information published online by the Salem Parks Department,Wallace Marine Park includes a variety of sports fields, open and forested park land, a boat ramp,floating docks, riverfront beaches, walking trails, picnic areas, and play equipment. Communityconcerns appeared to relate at least in part, to the parks location within the Willamette Riverfloodplain, and the attendant risk posed by sediment deposition during flood events. While no specificcontaminants were cited in conjunction with such sediment deposition, some discussion of upriverhistoric landfills occurred.

Prior to use as a park, historic aerial photos depict the site as either agricultural or undeveloped andvegetated land between 1954 and 1975. In 1984, development of the central baseball/softball fieldcomplex was visible. Use of the site as a park was consistent from that date forward. Surroundingland use was similarly rural/agricultural residential on western abutting properties through 1995, whenthe predominant land use began a transformation to a more commercially oriented pattern. Land on

the opposite side of the Willamette River was developed with relatively dense commercial andresidential structures from the time of the earliest available aerial photograph (1954).

Other upriver land uses have also included the Boise Cascade Paper Mill. Originally operating asOregon Pulp and Paper, that operation was located on the eastern bank of the Willamette River,approximately mile upriver from the southern edge of the park. At the earliest periods of operation,cooking liquor effluent from that plant was reportedly discharged to the Willamette River; from 1960to 1985, these wastes were redirected, and disposed of in unlined settling ponds located on thenorthern end of Minto-Brown Island, approximately mile upriver from the southern park edge.Remnants of those ponds remain visible in a 2002-dated aerial photograph (Figure 1). By 2007, papermill operations had discontinued, and the property was sold to private development interests.

The Brown Island Demolition Landfill is also located upriver from Wallis Marine Park and the PA sitesmore generally. At present, the full extent of landfill operations are not known, nor have details onwastes historically disposed of at that site been reviewed.

West Salem High School (Figure 6): West Salem High School occupies a single parcel thatincludes approximately 54 acres of land. This parcel is developed with the school building, athleticfields, and other parking and school related infrastructure. Regarding the athletic fields, these fieldsextend from the school parcel onto two adjacent lots owned by the City of Salem Parks Department;use of these athletic fields is shared by the parks department and school district. The school itselfincludes one interconnected, multi-story building. Based on a review of historic aerial photos,assessor records, and discussions with site knowledgeable individuals, the school was constructed inthe early 2000s.

Prior to construction of the school, aerial photos depict the property as undeveloped, with fruitorchards visible on the site back through at least 1954. Between 1954 and school development, thenumber of fruit trees on the property decreased, with those areas cleared of fruit trees being grasscovered, and/or vegetated. Assessor records list the prior usage of the school property as a cherryorchard and for grain cultivation. Prior to school development, other structures noted on the site werelimited to several small buildings located near the east central margin and northwest corner of theschool/ballfields property. Assessor records identify the eastern of these structures as residential butdo not provide information on the western structures.

Current site conditions are again considered typical for public school buildings; concrete block bearing

and exterior walls supported with metal columns and trussing define the majority of the structure, witha slab-on-grade foundation, a central boiler that supplies hot-water/steam for convective and forced-airheat, and interior finishes consisting of gypsum board, cellulose ceiling panels, vinyl floor tiles, andcarpet. Based on available information, the school does not include automotive or metal workingspaces. Four laboratory science classrooms were noted, with two on the ground-floor and two on thesecond story. These classrooms include lab benches with running water and natural gas, and non-reactive countertops. A utility trench runs through the floor of the two ground level laboratoryclassrooms. Chemicals used in each pair of laboratory classroom are stored in a room locatedbetween the two classrooms. The chemicals are segregated on shelving dependent on chemical type(i.e., inorganic, organic, sulfates, acetates, etc.). The storage rooms also have flammable and acidsstorage cabinets. Evidence of spills or releases was not observed on the floors.

Exterior areas at the school were primarily grass-covered, with asphalt drives and parking areas, and

landscaping at near-building locations. The site is located at one the crests on the locally rollingterrain, with the gradient generally sloping away from the site in all directions. Under bedding geologyis Grande Ronde Basalt, which can measure up to 400- to 600-feet thick. Surface water drainage inparking areas is predominantly managed by stormwater catchment basins observed in the pavedareas across the site. A surface water drainage trench/swale was also observed at the eastern edgeof the eastern parking lot, separating the parking area from the softball/baseball fields to the east. Thetrench/swale drains to the south, and apart from a localized area of standing water, was dry at the timeof STARTs site walk. Otherwise, surface water runoff in the area would appear to be collected byeither Glen Creek which runs to the south or an unnamed drainage channel mapped to the north ofthe site that also empties into Glen Creek. Glen Creek drains into the Willamette River, which islocated approximately 2.5 miles downstream from the site.

Surrounding property is residential, predominated by single-family dwellings. Similar to the site, this

surrounding property was agricultural before residentially developed. The nearestindustrial/commercial land use is approximately 1.25 miles southeast of the site, in the vicinity of theWalker Middle School/7

thand Patterson sites.

Orchard Heights Park (Figure 7): Orchard Heights Park is a single parcel that includesapproximately 28 acres of land; three additional parcels owned by the City are located along thesoutheast border of the site and while its not apparent whether those are formerly part of the park,one of these lots was noted to be used as a pea patch garden at the time of the site reconnaissance.Park development includes tennis and basketball courts, baseball diamonds, a swing set/play area,various trails and footbridges, and a dog off-leash area. The park as a whole is a combination ofcleared and forested land. Based on a review of historic aerial photos and assessor records, use ofthe site as a park appears to have begun sometime between 1975 and 1984. Prior to use as a park,


8/28

Page 7 of 17

the property appears to have been an undeveloped and predominantly cleared parcel. In the earliestphoto (1954), the southwest portion of the site appears to have been used as an orchard. Treesplanted in a grid remained visible in this same area up until sometime between 1987 and 1994.

Current site conditions are generally as described in the previous paragraph with a mixture of clearedand forested land interspersed with the various athletic fields, trails, and other recreational areas. Apaved driveway and parking lot provide access to the property from Orchard Heights Road, locatedalong the southern property margin. The site is located in a small, northern sloping valley area, withthe surrounding land sloping towards the site from the east, south, and west. Glen Creek transectsthe site on a north-south alignment. Under bedding geology is Grande Ronde Basalt, although thesites valley location would likely lend itself to the presence of more erosional, alluvial, and ancestralwetland type surficial deposits. Surface water drainage in parking areas is managed by storm-sewercatchment basins observed in the paved areas. Other drainage features noted included a catchmentbasin at the northwest corner of the baseball diamond area; a plastic drainage conduit discharging toGlen Creek; and smaller hand-dug ditches along the uphill edges of several trails. The source ofwater running from the conduit was not apparent. Other than runoff captured by the parking lot andballfield catchment basins, surface water runoff would be expected to discharge to Glen Creek viasheet flow. Glen Creek flows to the north, discharging to the Willamette River approximately 2.7 milesdownstream from the site.

Surrounding property is residential, predominated by single-family dwellings. Historically, much of thisdeveloped area appears to have been agricultural/orchard land. The nearest industrial/commercialland use is approximately 0.6 miles south-southeast of the site, along the Willamette River.

6. Conceptual Site ModelExample: Contaminant: MercuryTransport Mechanism: vapor moving on air currentsReceptors: people living in the house

Contaminants:Radium, Target Analyte List Metals, Semivolatile Organic Compounds, Pesticides, and PolychlorinatedBiphenyls

Transport Mechanisms:Airborne deposition, sediment transport, and surface water sheet-flow.

Receptors:

Direct contact, ingestion.

7. Decision StatementExamples: 1) Determinewhether surface contamination exceeds the established action level;2) Determine appropriate disposal options for contaminated materials.

The decision(s) to be made from this investigation is/are to:1. Determine if contaminants of concern are present and available to receptors at the target

properties included in this investigation.

2. Determine if there is elevated radiologic activity at the sites included in this investigation.

8. Action LevelState the analyte, concentration, and units for each selected action level. Describe the rationale for choosing each action level

and its source (i.e. MTCA, PRG, ATSDR, etc.) Example: The action level for total mercury in soil is 6.7 mg/kg (from RegionalScreening Level residential).

In accordance with CERCLIS requirements, analytical data from target samples will be compared tothat obtained from samples collected from an unaffected background location.

As a secondary point of comparison, analytical methods will be selected that allow for comparison toOregon Risk Based Criteria (RBC) Screening levels for the residential direct contact/ingestion scenarioand/or EPA Regional Screening Levels (RSL). Site action levels and laboratory reporting limits areincluded in Attachment A.

II. Data Acquisition and Measurement Objectives9. Site Diagram and Sampling Areas


9/28

Page 8 of 17

A Sampling Area is an area within in which a specific action will be performed.Examples : 1) Each drum on the site is a Sampling Area;2) Each section of sidewalk in front of the residence is a Sampling Area;3) Each sampling grid section is a Sampling Area.

Soil samples will be collected from target locations at four individual properties (Walker Middle School,7

thand Patterson, Orchard Heights Park, Wallace Marine Park) included in this project. Sediment

samples will be collected from Walker Middle School, Orchard Heights Park and Wallace Marine Park.These sites are each considered unique sampling areas. The site diagrams for each facility to besampled are attached as Figures 3 through 7. All sites will be screened for the presence of gammaradiation, which can be indicative of the presence of Radium 226.

10. The Decision RulesThese can be written as logical If, Then.. statements. Describe how the decisions will be made and how to address resultsfalling within the error range of the action level. Examples: 1) In the Old Furnace Sampling Area, the soil in the area aroundthe furnace structure will be excavated until sample analysis with XRF shows no mercury concentrations in surface soil abovethe lower limit of the error associated with the action level, 18.4 mg/kg. 2) If the concentrations of contaminants in a SA areless than the lower limit of the error associated with the action level, then the area may be characterized as not posing anunacceptable risk to human health or the environment and may be dismissed from additional RP activities. The area may bereferred to other Federal, State or Local government agencies.

The following statement(s) describe the decision rules to apply to this investigation:The soils and sediments at Walker Middle School, 7

thand Patterson, Orchard Heights Park, Wallace

Marine will be sampled. If the results are above RBCs, RSL, or significant as defined by CERCLA,additional sampling and/or remedial action may be recommended. If screening indicates that radiationlevels are higher at the sites in question, then additional characterization may also be recommended.

11. Information Needed for the Decision RuleWhat information needs to be collected to make the decisions this includes non-sampling info as well: action levels, climatehistory, direction of water flow, etc. Examples: Current and future on-site and off-site land use; wind direction, humidity andambient temperature; contaminant concentrations in surface soil.

The following inputs to the decision are necessary to interpret the analytical results: Analytical sample results for both target and background locations; Field screening data from gamma survey; Current and future on-site land use; RBCs (See Attachment A); and RSLs (See Attachment A).

12. Sampling and AnalysisFor each SA, describe:

1. sampling pattern (random, targeted, scheme for composite)2. number of samples, how many to be collected from where, and why3. sample type (grab, composite)4. matrix (air, water, soil)5. analytes and analytical methods6. name and locations of off-site laboratories, if applicable.

Walker Middle School (Figure 3):Up to 10 targeted soil and/or sediment samples will becollected from the site, including at least one soil sample from each area of exposed soil on thebaseball infields, and one sediment sample from the fence enclosed wetland area on the property.The remaining samples will be collected as warranted from areas of exposed soil identified duringsampling. Soil samples will be analyzed at a Contract Laboratory Program (CLP) laboratory

under EPA CLP SOW SOM01.2 for SVOCs (low and SIM level soil detection limits), Pesticides,and PCBs; for TAL Metals under EPA CLP SOW ISM01.3 for ICP-MS; and for radium at the EPANational Analytical Radiation Environmental Laboratory (NAREL). In addition, the two athleticfield areas and the grass covered area on the north side of the school will be field screened usinga Ludlum gamma meter inputting data to the VIPER system. The field screening will proceedusing parallel transects spaced at approximately 25-foot intervals.

TAL Metals under EPA CLP SOW ISM01.3 for ICP-MS; and for radium at the EPA NAREL. Inaddition, the property will be field screened using a Ludlum gamma meter. Field screening willproceed using parallel transects spaced at approximately 25-foot intervals.

Wallace Marine Park (Figure 5):Up to 10 targeted soil samples will be collected from the site,including at least one soil sample from areas of exposed soil on the baseball diamond infields.The remaining samples will be collected as needed from areas of exposed soil identified duringsampling. In addition, five sediment samples will be collected at the property boundary along theWillamette River shoreline, guided by the apparent level of use (i.e. samples will be biased forcollection at areas where greater use is noted). Soil and sediment samples will be analyzed at aCLP laboratory under EPA CLP SOW SOM01.2 for SVOCs (low and SIM level soil detectionlimits), Pesticides, and PCBs; and for TAL Metals under EPA CLP SOW ISM01.3 for ICP-MS. Aselect number of soil samples will be analyzed for radium at the EPA NAREL. In addition, the twocentral grass fields and softball/baseball areas will be field screened using a Ludlum gammameter. The field screening will proceed using parallel transects spaced at approximately 25-footintervals in these areas.

West Salem High School (Figure 6): The athletic field areas on the eastern and southernportion of the site as well as the gravel parking area on the northwest corner of the site will befield screened using a Ludlum gamma meter. Field screening will proceed using paralleltransects spaced at approximately 50-foot intervals.

Orchard Heights Park (Figure 7):Up to 5 targeted soil samples and 3 targeted sediment

samples will be collected from the site. These will include at least one soil sample from each areaof exposed soil on the baseball infield(s), with the remaining samples to be collected as warrantedfrom areas of exposed soil identified during field screening for radium. The three sedimentsamples will be collected along/within Glen Creek shoreline, guided by the apparent level of use(i.e. samples will be biased for collection at areas where greater use is noted) approximatelyevenly spaced intervals within Glen Creek. Soil and sediment samples will be analyzed at a CLPlaboratory under EPA CLP SOW SOM01.2 for SVOCs (low and SIM level soil detection limits),Pesticides, and PCBs; and for TAL Metals under EPA CLP SOW ISM01.3 for ICP-MS. A selectnumber of soil samples will be analyzed for radium at the EPA NAREL. In addition, the athleticfields and play areas on the park will be field screened using a Ludlum gamma meter. Thegamma field screening will proceed using parallel transects spaced at approximately 25-footintervals.

Background Location (Figure 8):To represent background conditions, soil and sedimentsamples will be collected from the Minto-Brown Island Park, located along the Willamette River.

At its closest point the park is located approximately one-mile upriver from Wallis Marine Park.Actual sample locations will be selected based on accessibility. Sampling will include thecollection of one soil sample and one sediment sample to be analyzed at a CLP laboratory underEPA CLP SOW SOM01.2 for SVOCs (low and SIM level soil detection limits), Pesticides, andPCBs; and for TAL Metals under EPA CLP SOW ISM01.3 for ICP-MS. As per therecommendation of EPA NAREL lab director, eight background samples (4 soil and 4 sediment)will be collected for radium analysis by the NAREL. One approximately 100x200 area will beselected for field screened using a Ludlum gamma meter. This area will be field screened usingparallel transects spaced at approximately 25-foot intervals.

13. Applicability of Data (place an X in front of the data categories needed, explain with comments)

Do the decisions to be made from the data require that the analytical data be:1) definitive data, 2) screening data (with definitive confirmation) or 3) screening data (without definitive confirmation)?

__X_A) Definitive datais analytical data of sufficient quality for final decision-making. To produce definitive data on-site or

off-site, the field or lab analysis will have passed full Quality Control (QC) requirements (continuing calibration checks,

Method Detection Limit (MDL) study, field duplicate samples, field blank, matrix spikes, lab duplicate samples, and other

method-specific QC such as surrogates) AND the analyst will have passed a Precision and Recovery (PAR) study AND the

instrument will have a valid Performance Evaluation sample on file. This category of data is suitable for: 1) enforcement

purposes, 2) determination of extent of contamination, 3) disposal, 4) RP verification or 5) cleanup confirmation.

Comments: Given the high level of public interest and potential for follow-on work stemming from this project,

data generated by fixed lab analysis would need to be definitive.


11/28

Page 10 of 17

__B) Screening data with definitive confirmationis analytical data that may be used to support preliminary or

intermediate decision-makinguntil confirmed by definitive data. However, even after confirmation, this data is often not as

precise as definitive data. To produce this category of data, the analyst will have passed a PAR study to determine analytical

error AND 10% of the samples are split and analyzed by a method that produced definitive data with a minimum of three

samples above the action level and three samples below it.

Comments:

_X__C) Screening datais analytical data which has not been confirmed by definitive data. The QC requirements are limitedto an MDL study and continuing calibration checks. This data can be used for making decisions: 1) in emergencies, 2) forhealth and safety screening, 3) to supplement other analytical data, 4) to determine where to collect samples, 5) forwaste profiling, and 6) for preliminary identification of pollutants. This data is not of sufficient quality for final decision-making.

Comments: Data generated by field screening instruments will be screening level only. This data is expected tosupport and/or be supported by confirmatory fixed lab analysis. Equipment will be appropriately calibratedduring use. No MDL study will be performed.

14. Special Sampling or Analysis DirectionsDescribe any special directions for the planned sampling and analysis such as additional quality controls or sample

preparation issues. Examples: 1) XRF and Lumex for sediment will be calibrated before each day of use and checked with asecond source standard. 2) A field blank will be analyzed with each calibration to confirm the concentration of non-detection.3) A Method Detection Limit determination will be performed prior to the start of analysis so that the lower quantitation limitcan be determined. 4) If particle size is too large for accurate analyses, the samples will be ground prior to analysis. If thesample contains too much moisture for accurate analyses, the sample will be decanted and air dried prior to analysis.

Field screening will involve the use of a Ludlum Model 44-20 detector and 2241 meter. Thiscombination provides an approximately 6-foot wide viewing window. The Ludlum will be set tooutput data to a VIPER data collection device. The VIPER allows for correlation of field collectedsample data to locational data collected concurrently using GPS units. Operational checks of theLudlum will be performed using an appropriate check source with 1 microcurie of Cesium-137 basedon previous AUM sites. While this data is being developed in its own right, findings from the gammasurvey will be used to guide selection of locations for follow-on soil sampling for radium analysis.

For comparative purposes, elevated gamma levels used to identify sampling locations will bedefined in comparison to both other site specific readings, and more broadly as compared tobackground levels detected at the Minto-Brown Island Park. For reference, HRS regulations defineelevated gamma levels as greater than or equal to 2 times the site specific background level. That

said, HRS regulations also require gamma readings be taken 1 meter from a potential source. As thisdata is being generated for screening purposes and focused on identifying the presence/absence ofgamma emitters, the 1-meter screening distance requirement may not be met during this study.

15. Method Requirements[Describe the restrictions to be considered in choosing an analytical method due to the need to meet specific regulations,

policies, ARARs, and other analytical needs. Examples: 1) Methods must meet USEPA Drinking Water Programrequirements. 2) Methods must achieve lower quantitation limits of less than 1/10 the action levels.3) Methods must be

performed exactly as written without modification by the analytical laboratory.]

Methods must have sufficiently low CRQLs or Method Reporting Limits to allow for data to becompared with RSL and/or RBC levels presented in Attachment A.

16. Sample Collection Information

[Describe any activities that will be performed related to sample collection]The applicable sample collection Standard Operating Procedures (SOPs) or methods will befollowed and include:Surface and Shallow Subsurface Soil Sampling SOP

Aquatic Sediment Sampling SOPField Activity Logbooks SOPEnvironmental Sample Handling, Packaging, and Shipping SOPSampling Equipment Decontamination SOP

17. Optimization of Sampling Plan (Maximizing Data Quality While Minimizing Time and Cost)[Describe what choices were made to reduce cost of sampling while meeting the needed level of data quality. Example: The

XRF will be used in situ whenever possible to achieve accurate results. Reproducibility and accuracy of in situ XRF analyses


12/28

Page 11 of 17

will be checked by collecting, air drying, analyzing and comparing five in situ samples at the start of sampling. Whereinterferences are suspected, steps will be taken to eliminate the interferences by mechanisms such as drying, grinding orsieving the samples or analyzing them using the Lumex with soil attachment.]

The selection of soil sampling locations for radium will be guided by results of gamma survey workperformed at the sites in question, with radium samples collected from areas/locations where elevatedgamma levels were measured (if any). If no elevated gamma levels are identified during field screening,samples will still be collected for confirmatory fixed lab analysis to verify negatives, or the presence ofgamma emitting radionuclides at levels below the field screening devices detection levels.
