Grid and Barrier Treatment Reduces Chlorinated Solvent Contamination

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.
