Abstract : This final report documents the Phase I contamination survey of Site 30-1, used from 1945 to 1951 as an impact area for 4.2 inch mortars. 66 Samples from 29 orings were analyzed for volatile and semivolatile organs and metals with separate analyses for AS and HG. CU, PB, and ZN were detected above indicator ranges; however, these elevated metal values are associated with Bedrock which consists of volcaniclastic material. No target organic compounds were detected. Metal anomalies were found at the site. A Phase II program consisting of 5 additional borings is recommended to investigate three areas which have not been fully investigated. The volume of potentially contaminated material present is estimated at 70,000 bank cubic yards. Appendices: Chemical Names, Phase I Chemical Data, Comments and Responses.
