Remediation of TNT & DNT in Homogenized Soil by using Daramend® Reagent

Daramend® Reagent was applied at pilot scale to approximately 100 tons of soil from the site, which was formerly used as a high explosives salvage and melt-out area from World War I through the 1920s.

Type of Site

Former Raritan Arsenal


Edison, New Jersey

Contaminants Treated



Homogenized soil from the site contained approximately 600 mg/kg of TNT/DNT. The solution soil excavated from the site was placed and treated in an Engineered Biotreatment Cell (EBC) constructed in a small building on the former arsenal property.


The pilot was scheduled to run for about 75 days but the demonstration ended early due to the rapid rate of treatment. After 56 days, the demonstration ended since the concentration of TNT was reduced to <5 mg/kg and amino-DNT was reduced to <3 mg/kg, which achieved the proposed remedial goals for the site.
