Manufacturing Facility, Dallas, TX
Subsurface investigations at this manufacturing facility revealed chlorinated solvent contamination in the groundwater. The contaminant plume contained significant levels of dichloroethene (cis-DCE) and vinyl chloride (VC) from the natural attenuation of tetrachloroethene (PCE) and trichloroethene (TCE). Well MW-9 contained the most significant concentrations of PCE, cis-DCE, and VC. Wells MW-5 and MW-13 showed elevated concentrations of only cis-DCE and VC. Accelerated natural attenuation using Hydrogen Release Compound (HRC®) was implemented to rapidly reduce these contaminant concentrations to the cleanup goals.
