A Phase II, Stage I Field investigation and evaluation was conducted. Twelve sites of potential environmental concern, grouped into six waste management zones, were evaluated. A total of 34 monitoring wells were installed and groundwater samples were obtained from each well. Soil samples were obtained for chemical analyses from 13 borings. Samples of storm sewer waters, surface water and bottom sediments were obtained. All chemical analyses were accomplished in accordance with standard USEPA analytical methods. Based on the sampling and analyses performed, levels of contamination were found in soils, sediments, surface water or groundwater at all 12 sites. Based on these findings, follow-up investigations have been recommended for further groundwater study, either through continued monitoring of existing wells or through expansion of the monitoring network, at all 12 sites.

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.

There may be nearly 300,000 waste sites in the United States where ground water and soil are contaminated. Yet recent studies question whether existing technologies can restore contaminated ground water to drinking water standards, which is the goal for most sites and the result expected by the public. How can the nation balance public health, technological realities, and cost when addressing ground water cleanup? This new volume offers specific conclusions, outlines research needs, and recommends policies that are technologically sound while still protecting health and the environment. Authored by the top experts from industry and academia, this volume: Examines how the physical, chemical, and biological characteristics of the subsurface environment, as well as the properties of contaminants, complicate the cleanup task. Reviews the limitations of widely used conventional pump-and-treat cleanup systems, including detailed case studies. Evaluates a range of innovative cleanup technologies and the barriers to their full implementation. Presents specific recommendations for policies and practices in evaluating contamination sites, in choosing remediation technologies, and in setting appropriate cleanup goals.
