Sea level: In this report, "sea level" refers to the National Geodetic Vertical Datum of 1929 (NGVD of 1929) a geodetic datum derived from a general adjustment of the first-order level nets of both the United States and Canada, formerly called Sea Level Datum of 1929.

Abbreviated chemical and physical units used in this report: Chemical concentrations and water temperature are given in metric units. Chemical concentration is given in milligrams per liter (mg/L) or micrograms per liter (Hg/L). Milligrams per liter is a unit expressing the concentration of chemical constituents in solution as weight (milligrams) of solute per unit volume (liter) of water. One thousand micrograms per liter is equivalent to one mil ligram per liter. For concentrations less than 7,000 mg/L, the numerical value is approximately the same as for con centrations in parts per million. Specific conductance of water is expressed in microsiemens per centimeter at 25 degrees Celsius (uS/cm). This unit is equivalent to micromhos per centimeter at 25 degrees Celsius (u,mho/cm), formerly used by the U.S. Geological Survey.

Chemical concentrations of constituents in a solid matrix are given in milligrams per kilogram (mg/kg). These units are used to express the concentrations of chemical constituents as weight of consituent concentrations in soils. Vol umes of headspace gas screenings are given in microliters (uL).

Results of Soil, Ground-Water, Surface-Water, and Streambed-Sediment Sampling at Air Force Plant 85, Columbus, Ohio, 1996

By James M. Parnell

ABSTRACT

The U.S. Geological Survey (USGS), in cooperation with Aeronautical Systems Center, Environmental Management Directorate, Restora tion Division, prepared the Surface-Water and Ground-Water Monitoring Plan for Air Force Plant 85 (AFP 85 or Plant), Columbus, Ohio, under the Air Force Installation Restoration Pro gram to characterize any ground-water, surface- water, and soil contamination that may exist at AFP 85. The USGS began the study in November 1996.

The Plant was divided into nine sampling areas, which included some previously investi gated study sites. The investigation activities included the collection and presentation of data taken during drilling and water-quality sampling. Data collection focused on the saturated and unsaturated zones and surface water. Twenty-three soil borings were completed. Ten monitoring wells (six existing wells and four newly constructed monitoring wells) were selected for water-quality sampling. Surface-water and streambed-sediment sampling locations were chosen to monitor flow onto and off of the Plant. Seven sites were sampled for both surface-water and streambed-sediment quality.

This report presents data on the selected inorganic and organic constituents in soil, ground water, surface water, and streambed sediments at AFP 85. The methods of data collection and anal ysis also are included. Knowledge of the geologic and hydrologic setting could aid Aeronautical Sys tems Center, Environmental Management Direc

torate, Restoration Division, and its governing regulatory agencies in future remediation studies.

INTRODUCTION

In 1980, the Department of Defense (DOD) devised a comprehensive Installation Restoration Program (IRP) to assess and to control the migration of environmental contamination that may have resulted from past operations and (or) disposal practices at DOD facilities. The IRP underwent changes under the Superfund Amendment/Reauthorization Act in 1986, which required all DOD facilities to follow guidelines and procedures set forth by the U.S. Environmental Protection Agency (USEPA). The U.S. Geological Sur vey (USGS), in cooperation with Aeronautical Systems Center, Environmental Management Directorate, Restoration Division, prepared the Surface-Water and Ground-Water Monitoring Plan (Parnell, 1996) for Air Force Plant 85 (AFP 85 or Plant), Columbus, Ohio, under the Air Force IRP to characterize any ground- water, surface-water, and soil contamination that may exist at AFP 85. The USGS began the study in Novem ber 1996.

Purpose and Scope

This report presents data on selected inorganic and organic constituents in soil, ground water, surface water, and streambed sediments at AFP 85. The meth ods of data collection and analysis also are included. Knowledge of the hydrogeologic system could aid Aeronautical Systems Center, Environmental Management Directorate, Restoration Division, and its governing regulatory agencies during future remedia tion sutides in determining the potential pathways for

Description and History of Study Area

AFP 85 is in Franklin County in the eastern part of Columbus, Ohio. The 288-acre site is in an urban industrial area adjacent to Port Columbus International Airport (fig. 1). AFP 85 began operations in 1941 as a naval aircraft production and maintenance facility. In 1982, the Plant was transferred to the U.S. Air Force from the U.S. Navy. Shortly thereafter, Rockwell Inter national was awarded the contract to produce the B-l bomber at AFP 85. Starting in 1988, the Plant was

operated for the U.S. Air Force by McDonnell-Douglas for the production of aircraft parts. In 1994, McDonnell-Douglas ceased operations. Since that time, the facility has been used for administration pur poses only by the Defense Finance Accounting Ser vice.

Over the years at AFP 85, operations included machining, metal finishing and electroplating, forming, painting and coating, and assembly. Waste associated with these activities included concentrated acids for metal cleaning and electroplating, process-tank slud ges, cyanide wastes, chromium solutions, lime sludges, spent degreasers, and paint strippers. Waste oils, sol vents, and aviation fuels were also collected and stored as part of the operations.

Previous Investigations

AFP 85 has been the subject of a several investi gations since 1982. The following briefs are based on a review of reports and supporting documents submitted by consultants and from project files (U.S. Air Force Aeronautical Systems Center, 1994); existing sites are shown in figure 2.

The IRP began in 1982 under a Phase I Hazard ous Materials Disposal Site Records Search. The pur pose of this study was to identify sites of potential environmental concern. Nine sites (1,2, 3,4,5,6,7,9, and 11) at AFP 85 were identified in the Phase I report.

A Phase II, Stage I, Investigation Confirmation and Quantification was completed in 1988. During the investigation, limited sampling was done at Sites 2 through 5 and 8.

A Phase II, Stage II, Remedial Investigation and Feasibility Study was completed in 1990. The work was completed in accordance with the National Contingency Plan enacted under the Comprehensive Environmental Response, Compensation, and Liability Act. This work involved Sites 3,4, 5, 8, and 10 and resulted in No Further Action Decision Documents.

In 1993, a Phase II Stage 2A study was done at Sites 3 and 4. Additional work was done at Site 11 under the Toxic Substances Control Act.

Site characterization work at Site 4 by the USGS and U.S. Army Corps of Engineers was done in Sep tember 1994. A U.S. Army Corps of Engineers data report was used to define the extent of possible contam ination by organic compounds at Site 4.

Introduction 3

METHODS OF STUDY

This report presents the data collected during drilling and water-quality sampling. Data collection focused on the saturated and unsaturated zones and sur face water. The various Plant areas are listed in table 1 and are shown in detail in figures 3 through 11 (at back of report).

Soil Sampling

A total of 23 soil borings were completed to determine the levels of anthropogenic and nonanthro- pogenic chemical compounds in the vicinity of the selected Plant areas. The size and specific location of each area was determined from previous investigations and (or) from aerial photographs if they were available. The total number of borings for each area were selected to be vertically and areally representative of the area. Two samples were selected from each boring on the basis of field-screening criteria described below and were sent to the contract laboratory for analysis. Total depths range from 2.3 to 95 feet.

Borehole drilling was done by use of an 8-1 /2-inch-inside-diameter (I.D.) hollow-stem auger. The continuous soil samples were collected for analy sis by use of a 60-inch-long, 4-inch-outer-diameter (O.D.) core-barrel sampler. The sampler was driven 30 inches or to refusal. Once driven, the barrel and rod were withdrawn from the auger and the sampler was removed from the rods. USGS personnel recorded descriptive (lithologic) logs in the field notebook (Appendix 1). Soil samples for chemical analysis con sisted of qualitative field screening followed by quan titative laboratory analyses. For the field screening, a portable organic vapor analyzer equipped with a flame ionization detector and a photoionization detector was used to analyze the borehole samples for volatile organic compounds (VOC's), progressing from one end of the core to the other. Sections of core identified as potentially contaminated by the analysis were pref erentially selected for the subsequent laboratory analy ses. Other samples were collected and sent to the laboratory on the basis of lithology. All borehole cut tings were drummed for later analysis and disposal by the Plant. All boreholes were grouted by injecting a bentonite/cement slurry until it overflowed at the sur face. Analyses for soil samples are listed in table 2. Analytical procedures used are outlined in the Surface-

water and Ground-water Monitoring Plan (Parnell, 1996). The results of the borehole screening are included on the boring logs in Appendix 1.

Monitoring Well Installation and Development

When a sufficient volume of ground water avail able to run selective chemical analysis was found dur ing soil-sampling drilling, a new monitoring well was installed within the significantly permeable zone. A total of four new monitoring wells were drilled for this study. Monitoring wells were constructed of 2-inch- I.D. polyvinyl chloride (PVC) Schedule 40 well casing and screens. The screens were flush threaded with a bottom plug. Slot size was 0.010 inch. Both 5-foot and 10-foot screen lengths were used, as determined by the borehole lithology. The screen was packed with a clean silica sand to 3 feet above the top of the screen. The final depth of the filter pack was sounded with a weighted metal tape. At least 2.5 feet of bentonite pel lets was placed on top of the filter pack. The annulus was grouted with a cement/bentonite grout to the frost line. The grout mix consisted of one 94-pound sack of Portland cement, 3 pounds of bentonite, and 6.5 gallons of potable water. Above-ground and below-ground monitoring (flush-mount) well completions were used. A 5-foot protective casing with a hinged lockable lid was used for above-ground completions, whereas a 10-inch flush-mount casing with a locking top was used for below-ground completions. A sloping con crete pad was constructed around each well to prevent surface-water intrusion. As-built well-construction diagrams showing the placement of the well screen, sand pack, bentonite seal, and grouting are compiled in Appendix 2. Construction details of existing wells are not presented in this report; for additional information, see U.S. Air Force Aeronautical Systems Center (1994).

All monitoring wells were developed by use of a precleaned disposable bailer and (or) a low-flow sub mersible pump. A minimum of 24 hours was allowed between well installation and well development. When the well was purged dry, the well was sampled upon recovery and within 24 hours. Specific conductance, pH, temperature, and turbidity were monitored during the development. Development continued until three consecutive readings of pH, specific conductance,

temperature, and turbidity stabilized. Field-measured characteristics were considered stable when pH's were within ± 0.1 unit, specific conductances were within± 10 |uS/cm, and temperatures were within + 0.5 C. Development time, volume of water produced, and field measurements were recorded in the field logbook. All water produced during development, and later dur ing decontamination activities, was contained at the field site. All equipment was thoroughly cleaned and decontaminated between locations to prevent cross- contamination, as outlined in the Surface-Water and Ground-Water Monitoring Plan (Parnell, 1996).

Ground-Water Sampling

Ground-water sampling locations were selected to determine the levels of anthropogenic and nonan- thropogenic chemical compounds in the vicinity of the selected Plant areas. A total of 10 monitoring wells were selected for this study. Six existing wells were inventoried and selected for sampling, and the four newly constructed monitoring wells also were selected.

Prior to purging and sampling, depth to water was measured to the nearest 0.01 foot. The volume of standing water in the well and in the sand pack below the grout seal were then calculated as one purge vol ume. Three purge volumes were removed in each well to replace the stagnant water with fresh water from the water-bearing formation. All monitoring wells were purged by use of a precleaned disposable bailer and (or) a low-flow submersible pump. If the well was purged dry, the well was sampled upon recovery and within 24 hours. A minimum of 10 well volumes of water, if possible, was removed from each well before sampling where turbidity was persistent (Ohio Environmental Protection Agency, 1995). The water samples were collected by filling the pre-preserved sample container either directly from the precleaned or dedicated bailer and (or) from a low-flow-rate dis charge tube from the submersible pump. After collec tion, the samples were chilled and shipped by overnight courier to the contract laboratory (Quanterra Environ mental Services, Denver, Colo.) for analysis. Analyses for ground-water samples are listed in table 2. Analyt ical procedures and standard operating procedures are outlined in the Surface-Water and Ground-Water Mon itoring Plan (Parnell, 1996).

Surface-Water and Streambed-Sediment Sampling

Surface-water and streambed-sediment sam pling locations were chosen to monitor flow onto and off of the Plant. The seven sampling sites are shown in figures 10 and 11 (at back of report). Mason's Run (fig. 10) is channeled with a concrete culvert through most of its extent within the Plant boundaries. It drains from the Port Columbus Airport, flows underground southward through the facility, and reemerges and exits the Plant entrance under Fifth Avenue. Turkey Run (fig. 11) is an intermittent stream that crosses the west ernmost segment of the Plant after passing through Port Columbus Airport. Approximately 375 feet of Turkey Run traverses the Plant property. An extensive onsite stormwater drainage system has been constructed throughout the plant property and drains into Mason's Run in the central part of the Plant, whereas some stormwater from the western part of the Plant drains into Turkey Run.

Surface-water and streambed-sediment samples were collected from the same sampling location, the surface-water sample being done first to minimize the collection of unnaturally suspended streambed sedi ments. Surface-water samples were collected as a grab sample from one point in the stream and put directly into the pre-preserved containers. Streambed-sediment samples were collected using a stainless steel scoop, transferred to a stainless steel bowl, and composited

Methods of Study 7

using the scoop. Sample jars were filled with the com posited material from the bowl. Samples for VOC analysis were not composited but were grabbed directly from the streambed. Field measurements of specific conductance, pH, temperature, and alkalinity were made directly from the surface-water body and are on file at the USGS office in Columbus, Ohio.

After collection, the surface-water and streambed-sediment samples were chilled and shipped by overnight courier to a contract laboratory for analysis. Analyses for surface-water and streambed-sediment samples are listed in table 2.

Quality-Assurance and Quality-Control Measures

Many measures were implemented by the USGS during data collection to ensure that the appropriate levels of quality assurance and quality control (QA/QC) were achieved. These measures served to ensure quality, precision, accuracy, completeness, and representativeness of the data generated during the study. The QA/QC measures were followed in accor dance with the Surface-Water and Ground-Water Monitoring Plan (Parnell, 1996). For all sampling types during the study, 100 percent of the analytical data gen erated by the laboratory were validated to determine completeness of the data-package deliverables and achievement of the specific data objectives. An inde pendent environmental firm was contracted by the USGS to perform the data validation; a summary of the data-validation process is presented in the Technical Memorandum for the Surface-Water and Ground- Water Monitoring Plan (Parnell, 1997). The results of samples analyses for soil, ground-water, surface-water, streambed sediment, and QA/QC samples are pre sented in Appendix 3.

GEOLOGY AND HYDROLOGY

The Plant lies within the Till Plains section of the Central Lowland Physiographic Province (Fenneman, 1938). Till Plains were formed through glaciation and burial of preglacial topography. Soils belonging to the Bennington-Pewamo Association are present at AFP 85 (U.S. Department of Agriculture, 1977). The soils range from a yellowish-brown silty loam to a gray clay loam and are generally wet to ponded, easily eroded, and poorly permeable.

Glacial till interbedded with glacial outwash is the predominant surficial material at AFP 85 (fig. 12, at back of report). The glacial outwash is composed of fine, well-sorted sand and gravel-sized material, whereas the glacial till is unstratified, poorly sorted material composed of a mixture of clay, sand, gravel, and various sizes of boulders (Battelle Denver Opera tions, 1989). Glacial tills and outwash deposits were cut by more recent outwash channels, resulting in com plex interbedding and lateral and vertical facies changes within relatively short distances. This glacial interfingered outwash and till results in laterally and horizontally discontinuous water-bearing zones beneath the Plant but does not form a continuous aqui fer (Battelle Denver Operations, 1989). Geologic logs of the boreholes indicate that the glacial till ranges in thickness from 10 to 85 feet and that average thickness is about 25 feet across the Plant. It has been reported that a major tributary to the main buried channel of a preglacial river flowed beneath what is now the south ern boundary of AFP 85 (Battelle Denver Operations, 1989). Drill logs (USB04 and USB20) in this area, however, indicate that the lithology is clay with some gravel arid cobbles to the top of the shale bedrock, not indicative of a buried channel. The preglacial river noted in the same report was reported to cut a channel approximately 200 feet below land surface. Logs of the new borings in this area (USB04 and USB 15), how ever, indicate that the depth to the shale bedrock was 83 feet and 95 feet, respectively.

Three major aquifer systems are present in Fran klin County: Devonian limestone aquifers, Mississip- pian sandstone aquifers, and glacial aquifers. Thin, discontinuous, glacial water-bearing units underlie AFP 85, as described above. Well yields in the glacial system are as much as 2 gallons per minute from the two water-bearing zones underlying the Plant (U.S. Air Force Aeronautical Systems Center, 1994).

Isolated water-bearing zones also lie within till as a discontinuous basal deposit of coarse sand and gravel just above the shale bedrock. This discontinuous unit is of varied thickness, according to information in drilling logs. Beneath the glacial till at AFP 85 lies the Ohio Shale, which is generally considered to be a poorly permeable unit. This black to dark-brown, sandy, fissile shale has a high organic content.

The gross lithologies recorded for previous wells and borings at the Plant are similar to those found in the new borings, but proportions of clays, sands, and grav els differ greatly from area to area. Figure 13 (at back


of report) shows a cross section of monitoring wells across the Plant and its variability in geology. The vari ability in lithologies and the discontinuity between sand and gravel lenses makes mapping of any specific unit extremely difficult. Because of this heterogeneity of the unconsolidated deposits, no attempt was made to interpolate the stratigraphy between the wells and bor ings.

Infiltration from creeks and streams may recharge the water-bearing units; however, much of the surface water is collected and diverted by tile drainage into concrete channels in and around the Plant.

Selected Metals and Trace Elements

Soils contaminated by metals and trace elements are common at many industrial sites in Ohio. The pres ence of trace elements, however, does not necessarily indicate contamination because all soils contain at least some trace concentrations. Contamination by metals and trace elements are commonly determined by com paring background concentrations from nearby loca tions to site-specific locations. Background metals concentrations for soils in Ohio were compiled by Cox-Colvin & Associates (1995); arsenic, barium, chromium, lead, and mercury are listed as common industrial background metals in Franklin County. These metals were also common to AFP 85.

Of the 23 analytes, 11 were detected in all soil sampled: aluminium, barium, calcium, cobalt, chro mium, copper, iron, magnesium, manganese, vana dium, and zinc. Other metals beryllium, potassium, molybdenum, nickel, and lead were found in more than 70 percent of the samples. Silver, sodium, thal lium, antimony, and selenium were below the detection limit in all soil samples. A list of validated selected metals and trace elements found in soil are given in Appendix 3.

ground-water samples and nine QA/QC samples were collected. Ground water is not a source of potable drinking water for the Plant.


Only one VOC was detected in all water from the 10 wells sampled: benzene, at 1.9 mg/L in USW02.

Semi volatile Organic Compounds

Only one SVOC was detected in all ground- water samples from the 10 well: bis(2-ethylhexyl)phthalate, at 31 mg/L in PG-201.


Only two unqualified pesticides were detected in all ground-water samples: delta BHC, at 0.088 mg/L in PG201, and heptachlor expoxide, at 0.070 mg/L in USW02. All PCB concentrations were below the detection limit.


Of the 23 analytes, 3 were detected in all wells sampled calcium, magnesium, and manganese. Beryllium, silver, cobalt, copper, nickel, antimony, selenium, vanadium, and thallium concentrations were below the detection limit. Cadmium (0.0083 mg/L) at PG201 and chromium (1.4 mg/L) at USW16 exceeded the Maximum Contaminant Levels of 0.0050 mg/L and 0.100 mg/L, respectively. A list of validated selected metals and trace elements in ground water is given in Appendix 3.

CONCLUSIONS

The Surface-Water and Ground-Water Monitor ing Plan for AFP 85 was designed to characterize any ground-water, surface-water, and soil contamination that may exist at AFP 85. The investigation activities done by the USGS included the collection of data dur ing drilling and during sampling of ground water, sur face water, and streambed sediments.

This report presents data on the selected inor ganic and organic constituents in soil, ground water, surface water, and streambed sediments at AFP 85. The methods of data collection and analysis are also included. The analytical results of the soil, ground water, surface water, and streambed sediments could aid Aeronautical Systems Center, Environmental Man agement Directorate, Restoration Division, and its gov erning regulatory agencies in determining the potential pathways for contaminant migration into the underly ing water-bearing zones or nearby surface waters and will provide background information for future reme diation studies.

The unconsolidated glacial till deposits at the Plant consist of poorly sorted outwash; very fine to coarse sand and gravel is intermingled with poorly per meable clay and cobbled till. Because of this heteroge neity of the unconsolidated deposits, no attempt was made to interpolate the stratigraphy between the wells and borings.
