| Abstract |
The Savanna Army Depot Activity (SVADA) site, an active military installation, is located 70 miles west of Rockford, Illinois, in a remote and sparsely populated area. From 1943 to 1969, ammunition washout operations were conducted in the northwestern portion of the facility. As a result, wastewater containing explosive compounds was produced, discharged to a drain trough, and piped to four unlined lagoons, referred to as the 'lower lagoons,' which drained into a ditch and onto the Mississippi River. Since 1979, the SVADA lagoon ares have been the subject of several U.S. Army investigations, which revealed significant contamination of the soil with high concentrations of the explosive trinitrotoluene (TNT) and other organic compounds. The soil is also a continued source of ground water contamination. The ROD addresses a final remedy for the Washout Lagoon Area Soil at SVADA as OU1. A future ROD will address the ground water in the vicinity of the lagoons. The primary contaminants of concern affecting the soil are organics, including TNT; nitrobenzene (NB); 2,4,6-TNT; 2,4-dinitrotoluene (DNT); 2-amino-4,6,DNT; 1,3,5-trinitrobenzene (TNB); and hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX). The selected remedial action for the site are included. |
