Abstract : This final report documents the phase I contamination survey of site 3-4, a possible DBCP spill area in the railroad yards. 91 samples from 26 borings were analyzed for voltatile and semivolatile organics and metals with separate analyses for AS, HG, and C6H6, CCL4, TCLEE, CD, ZN, AS, and HG were detected within or above their indicator ranges; however, the CD, ZN, AS, and HG concentrations appeared to be consistent with naturally occurring levels. DBCP was not detected in these samples, but it was found in a petrex soil gas investigation. A phase II program consisting soil present is estimated at 5,000 cubic yards. Appendices: chemical names, phase I chemical data, comments and responses, a letter technical plan date September, 1987.
