Frank Wear Site Cleanup Action
Hart Crowser developed cleanup action alternatives and construction for a site contaminated with chlorinated solvents, under our Washington State Department of Ecology on-call contract. The work was done under constraints such as access issues associated with an active facility and multiple property owners. The site hydrogeology is complex, with large groundwater level fluctuations and a seasonal change in groundwater flow. Our work included assessing site conditions, establishing remedial action objections and selecting remedial actions. The remedy selection included cost analysis and computer modeling of long-term alternative effectiveness. A groundwater treatment system designed by Hart Crowser has shown a substantial reduction in perchloroethylene (PCE) mass.
