A chlorinated solvent plume is impacting soil, groundwater, and soil vapor in Seattle’s Georgetown neighborhood. Aspect is working on behalf of Art Brass Plating to investigate and cleanup the plume. Our work includes completing the RI, initiating a source control air sparging/soil vapor extraction system, and leading public participation over an approximate six block area. We also monitor and mitigate against vapor intrusion potential in more than 20 neighboring buildings to protect against exposure while groundwater remediation progresses. We negotiated an Agreed Order with Ecology that enables facility-specific investigation and coordinated data sharing with the area potentially liable parties (PLPs).
