Draft Final Source Reports, 36 UNC, 36-3, and 36-17. Phase 2, Section 36, Task Number 1.

摘要

This report documents the Phase I contamination survey of site 36-17 which was used for disposal of solid wastes in pits and trenches. 99 samples from 46 borings were analyzed for volatile and semivolatile organics and metals with separate analyses for Hg, As, and DBCP. High levels of Cr, Cu, Zn, Dieldrin, Endrin, DIMP, Chlordan, DBCP, CPMS, and Aldrin were detected in the samples. Metal anomalies were also detected at the site. An extensive Phase II program consisting of 40 additional borings and more geophysical investigations is recommended to better locate the disposal trenches. The volume of contaminated material present is estimated at 2,603,000 cubic yards. Appendices contain Photographs and Phase I analytical data. -BKA.
