Abstract : This final report documents the Phase I contamination survey of Site 36-3, a series of trenches and pits believed to have been used for disposal of insecticides. Sixteen samples from 8 borings were analyzed for volatile and semivolatile organics and metals with separate analyses for Hg, As, and DBCP. Predominant contaminants are Hg, ALDRN, and DLDRN; however, As, Cd, Pb, ENDRN, ISODR, CPMS, CPMSO, CPMSO2, DBCP, C6H6, CH2Cl2, DCPD, CHCl3, BCHPD, TCLEE, and MeC6Hs were also detected above their respective indicator ranges. Metal anomalies may also be present at the site. A Phase II program consisting of 28 additional borings is recommended to define the outer extent of soil contamination and confirm the accuracy of the geophysical investigation in identifying the disposal trenches. The volume of contaminated soil present is estimated at 73,000 bank cubic yards. Appendices: Chemical names, Phase I chemical data, comments and responses. -BKA
