The Louisiana Army Ammunition Plant (LAAP) is listed on the National Priorities List. The site is a 15,000-acre Federal facility located in Shreveport (Webster Parish), Louisiana. On-site ground water beneath 16 unlined surface impoundments near the southern boundary is contaminated. Access to LAAP is restricted and under 24-hour security. Contaminants include 2,4,6-trinitrotoluene (TNT), cyclonite (RDX), trinitrobenzene (TNB), and homocyclonite (HMX). Preliminary on-site sampling results have identified TNT (493,133 ppm in sediment/subsoil, 483,556 ppm in sludge, 1,033 ppm in surface soil, 7 ppm in surface water, and 18 ppm in ground water), RDX (60,224 ppm in sediment/subsoil, 602 ppm in surface soil, 60,224 ppm in sludge, and 14 ppm in ground water), TNB (2 ppm in surface water and 8 ppm in ground water), and HMX (4 ppm in ground water). Based on available information, 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.
