The purpose of this task is to undertake a field investigation at Sheppard AFB TX to determine the presence or absence of contamination within the specified areas of investigation; if contamination exists, determine the potential for migration of those contaminans in the various environmental media; identify additional investigations necessary to determine the magnitude, extent, direction and rate of migration of discovered contaminants; and identify potential environmental consequences and health risks of migrating pollutants. The Phase I IRP Report incorporates the background and description of the sites for this task.
The Phase II (Records Search) Installation Restoration Program study at Sheppard AFB initially identified twenty-three individual sites of potential environmental concern. Of these twenty-three, eleven sites were identified as possibly containing hazardous waste. These sites were evaluated using the USAF Hazard Assessment Rating Methodology (HARM). Based upon the HARM scores, four of the eleven sites were identified for Phase II investigations. This investigation (Phase II stage 1) was conducted between October 1984 and February 1985, and included geophysical surveys, the installation and sampling of nine ground-water monitoring wells, coring and sampling of shallow soils at two of the four sites, and sampling and analysis of surface water from seven locations near the waste sites. Keywords: Installation restoration, Groundwater sampling, Surfacewater sampling, Soil sampling, Remedial action, Hazardous waste, Geophysical surveys, Monitoring wells.
Volume 2, which consists of appendices, includes the following: Sample locations; Well logs; Field data; Sampling and analysis instructions; Chain-of-custody forms; Analytical results; Dover AFB waste management summary tables; and Calculations.
The overall objective of the Installation Restoration Program (IRP) Phase II investigation is to assess potential contamination at past hazardous waste disposal and spill sites on Air Force installations. A series of staged field investigations may be required to meet this objective. The intention of this staged investigation is to undertake a field and laboratory study at Air Force plant 59, Johnson City NY: (1) to confirm the presence or absence of contamination with in the specified areas of investigation; (2) if possible, to determine the extent and degree of contamination and the potential for migration of those contaminants in the various environmental media; (3) to identify public health and environmental hazards of migrating pollutants based on State or Federal standards for those contaminants; and (4) to delineate additional investigations required beyond this stage to reach the Phase II objectives. The Phase I IRP Report (mailed under separate cover) incorporate the background and description of the sites/zones for this task. Keywords: Hazardous materials wastes, Environmental protection.

Ecology and Environment, Inc., was retained by the USAFOEHL/TS to provide technical and analytical services in support of the Air Force Installation Restoration Program (IRP). These services were applied to the Phase II, stage 1, investigation at Air Force Plant 3, Tulsa Oklahoma. The investigation included records searches, geophysical studies, and sampling of surface and subsurface soils and groundwater. Samples were analyzed for various parameters including volatile organics, oil and grease, TOX, TOC, phenols, PCBs, and titanium. Results of the investigation indicated that past waste handling and disposal practices had caused various degrees of soil and groundwater contamination at six of the seven sites. Follow-up (Stages 2) work has been recommended at five sites to better define the extent of contamination. One site was judged to require no follow-up action, and one site is recommended for Phase IV (remedial action) work.
A Phase II, Stage I site investigation has been performed at the USAF Plant No. 59 (AFP 59) in Johnson City, New York. AFP 59 is located in an industrial area adjacent to the Susquehanna River. The site overlies the Clinton Street-Ballpark Valley aquifer which consists of glacial valley fill sediments of clay, silt, sand and gravel. This aquifer is a major source of groundwater in the area and has been designated a sole source aquifer. As part of the field investigation a total of three shallow monitoring wells were installed to depths of 26-29 feet. Three shallow test borings (10 feet) were also drilled near the plating operations. Fifteen (15) subsurface soil samples plus QA/QC samples were submitted for laboratory analysis. The solid samples showed trace levels of EP Toxicity metals which were below EP Toxicity maximum contaminant levels. Groundwater samples were collected from the 3 wells installed during the investigation and from one production well at the site. Two metals (cadmium and lead) and two organics (trichloroethane and trans-1,2-dichloroethene) were detected in samples at levels equal to or in excess of current relevant criteria, standards or guidance values. Analytical results indicate some correlation with chemicals reportedly stored and used in industrial processes at AFP 59 in the past. The distribution of similar contaminants in groundwater and soil were inconsistent throughout the site. A major receptor near AFP 59 is the impact this contamination may have on municipal water supply wells within 1000 feet southwest of the site. (aw).
The overall objective of the Phase II investigation is to define the magnitude, extent, direction, and rate of movement of identified contaminants in the ground water. A series of staged field investigations may be required to meet this objective. The contractor shall recommend any additional investigations required beyond this stage including an estimate of costs. The purpose of this task is to undertake a field investigation at Beale AFB Ca: (1) to determine the presence or absence of environmental contamination within the specified areas of investigation; (2) if contamination exists, to determine the potential for migration of these contaminants in the various environmental media; and (3) to identify potential environmental consequences and health risks of migrating pollutants based on applicable local, state and/or federal standards.
An Installation Restoration Program (IRP) Phase II, Stage 1 investigation was conducted at USAF Plant 42 in Palmdale, California, to confirm the presence or absence of contamination at 23 sites. Contamination was suspected at the sites as a result of past spills, leaks, or waste disposal practices. A field investigation program was conducted, consisting of soil boring and sampling, groundwater sampling, and chemical analysis of environmental samples (water and soils) for suspected contaminants. No significant contaminants were found at 17 of the sites. Fuel contamination (petroleum hydrocarbons or oil & grease) was detected at 5 sites, 3 of which also had volatile organics present. Remedial action was recommended for 2 sites because of the location and amount of contaminants detected.
Methyl ethyl ketone analysis was performed by Radian chromatography laboratory. The results of the analysis are in a memo included in this volume. All other samples for chemical analysis were submitted to Radian Analytical Services Laboratory. The samples were logged in, and the data reported in batches . Each batch submitted was assigned a RAS work order number. Volume 2, Volume 3, and Volume 4, Appendix A-1 contain the analytical data reports for the various batches of samples. The bulk of data necessitated the results be bound in three volumes. Volumes 2, Volume 3, and Volume 4, Appendix A-1 contain Tables A.1-1, A.1-3, and A.1-5, respectively, which are a sequential listing of the reports contained in that volume by batch number and Tables A.1-2, A.1-4, and A.1-6, respectively, which are a sample log and cross-reference table. These tables serve as a sample log and cross-reference well numbers, OEHL numbers and the RAS work order numbers under which the results are located. Pages in Appendix A are numbered by the volume number followed by the page number of that volume. For example, Page 2 001 is the first chemistry data page of Volume 2.
