Health assessment for Milan Army Ammunition Plant, Milan, Carrol and Gibson Counties, Tennessee, Region 4. CERCLIS No. TND210020582. Preliminary report

Technical Report · Mon Apr 10 00:00:00 EDT 1989

OSTI ID:7244807

The Milan Army Ammunition Plant Site (MAAP) is located in Milan (Carrol and Gibson Counties), Tennessee. MAAP produces munitions for the U.S. Army. From 1942 to 1978 wastewater from a munition demilitarization process line was discharged into 11 unlined settling ponds. These ponds were dredged in 1971 with the soils placed near the side of the ponds. A multilayer cap was placed on top of the ponds and the dredged soils (1984). Access to the site is restricted. Removal actions have not occurred. Preliminary on-site groundwater sampling results have identified cyclonite (RDX), homocyclonite (HMX), 2,4,6-trinitrotoluene, 2,6-dinitrotoluene, 2,4-dinitrotoluene, 1,3,5-trinitrobenzene. In addition, cadmium, chromium, and lead were detected in on-site groundwater. Off-site surface water sampling results identified RDX and HMX. The site is considered to be of potential public health concern because of the risk to human health caused by the possibility of human exposure to hazardous substances. Direct contact and ingestion with groundwater from on-site wells, off-site soils and bioaccumulation of site-related contaminants in fish, waterfowl, and crops with uptake from irrigation, and subsequent ingestion by area residents are possible human exposure pathways.
