Reactive Gas Process for In Situ Treatment of 1,2,3-Trichloropropane in Vadose Zone Soils

Abstract

The key objective of the project was to determine whether the application of gaseous NH3 to unsaturated soils can be effective for increasing soil pH and subsequently for treating TCP, 1,2-DCP, 1,3-DCP, DBCP and other priority contaminants subject to alkaline hydrolysis. A secondary objective was to determine if addition of NH3 to soils promotes a cometabolic polishing effect due to induction of the enzyme AMO within microorganisms present near the treatment zone. If this effect could be documented, it would represent a separate mechanism of contaminant destruction, and possibly a separate treatment approach using lower NH3 concentrations.
