Site investigation revealed elevated levels of tetrachloroethene (PCE) in the subsurface soils to a depth of 10 feet. The soils consisted of a stiff silty clay and the PCE had impacted a total volume of 1,080 cubic yards. Due to a number of subsurface utilities present at the site and the shallow nature of the contaminants, our patented fluid-jetting system was utilized to advance the probe rod into the subsurface on a 3 foot injection matrix.

With the exception of sampling location GP-9, the site specific cleanup objective of 1 mg/ kg was achieved with a single treatment event within two months. The following table shows the analytical results in mg/kg.
