Document, Report, or Work plan Review - other |
2014- Draft Multiple Compliance Restoration Program Sites RI Work Plan received March 1, 2014. In 2012, SER activities were preformed to evaluate the presence of contamination and if present, help to improve delineation of the extent of contamination. 9 soil and 3 groundwater samples were collected and analyzed for DRO, RRO, GRO, VOC, SVOCs, PCBs and metals. Methylene chloride was present in samples, but since it was also detected in calibrations blanks it was removed for COPC list. Arsenic exceeded screening levels for both soil and groundwater samples. Additional field work is expected in the 2014 field season. |
