Situation
The test site is an inactive and unoccupied government-owned Operations Support Command site that was previously active from 1941 to 1992. The selected test area was approximately 45′ x 20′ in size. Based on an initial sample, primary explosives of concern (and associated baseline levels of contamination) were: TNT (383 mg/kg), RDX (380 mg/kg) and HMX (185 mg/kg). Discrete sampling (EPA Method 8330A) was utilized at target hot spots with visible evidence of explosive compounds on soil surface. The average concentration of primary explosive compounds were TNT (3,347 mg/kg), RDX (5,977 mg/kg), and HMX (640 mg/kg). Other explosive compounds were detected in the soils at much lower concentrations.
Solution
MuniRem® Environmental conducted a baseline characterization of the contaminated soil to determine the type and concentration of explosives present. MuniRem® activators and main reagent were tilled into the explosive contaminated soil. Water was then added to initiate the rapid explosive degradation reaction by MuniRem® reagent. The efficacy of the treatment was monitored 24 hours following application and was confirmed two weeks thereafter.
