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 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.

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.
Three sites were investigated at Elelson AFB during the Phse II, Stage 2 field evaluation of the IRP. The sites were the sewage treatment plant spill ponds and treated effluent leaching ponds (Site 32) and two base landfills (Sites 2 and 1). A geophysical survey was performed in the vicinity of the sludge treatment plant to help define areas of high electromagnetic conductivity (i.e., potential contamination) and aid in the placement of monitor wells. Eight monitor wells were installed during Stage 2. Ground water samples from Stage 1 and Stage 2 wells were analyzed for purgeable lead, arsenic, cadmium, chromium, mercury and silver. Soil samples from the vicinity of one of the landfills (Site 1) were tested for the presence of pesticides. Trace quantities of purgeable halocarbons and petroleum hydrocarbons were detected in the wells from all three sites. Drinking water standards for total trihalomethanes were not exceeded for any of these samples. Arsenic and cadmium were detected in wells at concentrations were elevated in the vicinity of the sewage treatment plant. Only one well, in close proximity to the sewage sludge drying beds, was found to have nitrate, nitrite concentrations above the Primary Drinking Water Standard. A well downgradient from this site had nitrate, nitrite levels below the same standard. Soils at Site 1 contain trace quantities of DDE, DDD, and DDT. No pesticides were detected in groundwater from the monitor well at this site.
