Abstract
The Sewer Systems Medium Group consists of nine exceedance sites that are located throughout RMA. The sewer lines in these sites conveyed chemical, sanitary, and process water wastes. Release of contaminants at these sites was caused by spillage or leakage from broken pipes or faulty joints and manholes in the sewer lines. It has been inferred that some of the soils along the piping runs is contaminated, but the actual areas of contamination have not been well documented due to the difficulties in identifying points of leakage without excavating the entire piping runs. The contaminated soils are typically at depths greater than 6 ft below the surface (based on the depth of the sewer piping). These nine sites are subdivided by type and contamination pattern into two subgroups, the Sanitary/Process Water Sewers Subgroup (Figure 13.0-1) and the Chemical Sewers Subgroup (Figure 13.0-2). p49
