Client Testimonial: Washington Superfund
Site
“Due to a combination of subsurface
conditions and the limitations of pump and treat technology,
our Washington Superfund client needed an in situ remedy
to address recalcitrant Cr(VI) and TCE contamination in
groundwater. Concentrations of Cr(VI) and TCE in the hot
spot area were approximately 200 ppb and 8 ppb respectively.
EA evaluated a number of products capable of addressing
these commingled contaminants, and chose Adventus Group’s
EHC-M because it supports both chemical and biological
reduction processes, resulting in greater longevity over
other products due to the ZVI component. EHC-M was applied
using direct push injection at depths of 80 to 90 feet
below the surface and, within 3 months of the application,
Cr(VI) and TCE concentrations were below detection limits.”
