POSTER PRESENTATION

Regulatory Directed CVOC Vapor Intrusion/Mitigation and Remedial Approach Site

In 2009, the Michigan's DEQ began state-funded activities at an industrial plating facility in southwest Michigan to determine the nature and extent of contamination emanating from an area of the facility where degreasing agents were used. CVOC's impacted groundwater was identified in a ¼ mile long shallow plume ranging from 2-5 feet in depth migrating from the site and through a residential area. Further investigation of the residences identified contaminated groundwater within many of the basements sumps, posing a potential VI threat.? REMEDY ADDRESSING DIRECT CONTACT AND VAPOR INTRUSION - The basement sumps were capped and vented and a contaminant vapor intrusion protection coating (Retro-Coat™) was applied to the floor and walls of the residential. GW REMEDIATION - For the groundwater plume, a multi-phase injection approach including electron donor, bioaugmentation and liquid activated carbon (LAC) substrates was implemented. Biobarriers were used for future migration of residual CVOCs.
