Abstract:

The North Central Study Area NCSA report integrates the study area history, geology, and hydrology with the results of soil, surface water, ground water, air, biota, and structures investigations to define the nature and extent of contamination of the central and northern areas of RMA. The NCSA includes the disposal basins, interconnecting ditches and adjoining sites, the sewer systems, and the north and northwest boundary contaminant systems. The chemical sampling program included analysis of 2,186 samples from 965 bores and monitoring of over 230 wells and 8 surface water locations. The most widely distributed contaminant group is organochlorine pesticides. The volume of potentially contaminated soil is estimated to be 9.2 million cubic yards.
