“…These wells and the neutronaccess borehole are either in or near Fortymile Wash. Depth-to-water measurements were made in three other wells near Fortymile Wash, 5-12, J-13, and JF-3, during water years 1993-94 but are reported in other publications (Hale and Westenburg, 1995).…”

Squires and Young (1984), Pabst and others (1993), and Kane and others (1994) investigated streamflow in Fortymile Wash. Streamflow and precipitation data for the Fortymile Wash area collected during water years 1991-93 are included in a statewide report (Emett and others, 1994).…”

“…Groundwater impact is unlikely because the depth to groundwater is extensive (approximately 1,000 ft at the nearest well [Hale and Westenburg, 1995]) and the environmental conditions at the site (i.e., arid climate, high evaporation) are not conducive to downward migration of COPCs.…”

Approved for public release; further distribution is authorized.Printed on Re cycle P ap er • Contaminants of potential concern, if present, are associated with sanitary effluent and/or with the unintentional release of contaminants from the Test Cell 'C' Facility buildings that were serviced by the sewage lagoons.• Contamination within the sewage lagoons, if present, will be confined within the boundaries of the sewage lagoons.• Radionuclides, although not anticipated, may be present due to activities related to the Nuclear Rocket Development Station program and with use of the Radiological Safety trailer at the Test Cell 'C' Facility.• Contaminants of potential concern at the sewage lagoons are limited vertically to less than 3 feet and laterally within the bermed area.• Extent of contamination in the swale, if any, is unknown. Potential exists for down-gradient migration. • Groundwater impacts are not anticipated because the water level of the nearest well is approximately 1,000 feet.• Exposure pathways are ingestion, inhalation, and dermal contact.A more detailed conceptual site model is presented in Section 3.0 and Section A.2.0 of Appendix A of this Corrective Action Investigation Plan. The conceptual model serves as the basis for the sampling strategy.The technical approach for investigating this Corrective Action Unit consists of the following activities:• Collect surface and subsurface samples using a direct-push method.• Conduct field screening to direct sampling activities and provide a qualitative assessment of conditions.• Collect samples from step-out locations, as necessary, to define the extent of the contaminants of potential concern, if present.• Conduct laboratory analysis of selected environmental samples.• If necessary, conduct a Stage II field investigation using drilling to investigate the vertical and/or lateral extent of contaminants of potential concern that may exist beyond the reach of the direct-push method. Test Cell 'C' (TCC) Facility and were used for the discharge of sanitary effluent from the TCC facility. For purposes of this discussion, this site will be referred to as either CAU 232 or the sewage lagoons. PurposeThis CAIP presents a plan to investigate CAU 232. The purpose of the corrective action investigation is as follows:• Identify the presence and nature of contaminants of potential concern (COPCs).• Determine the vertical and lateral extent of COPCs.• Provide sufficient information and data to determine the need for corrective actions. Develop and evaluate appropriate corrective actions for the sewage lagoons. This CAIP was developed using the U.S. Environmental Protection Agency's (EPA) Data Quality Objectives (DQOs) (EPA, 1994) process to clearly define the goals and set the DQOs for collecting environmental data and to design a data collection program that will satisfy these goals. A DQO scoping meeting was held prior to preparation of this plan; a brief summary of the DQO process is presented in Section 3.4. ScopeThe scope of this CAIP is to resolve the problem ...
