The groundwater beneath an eight-acre shopping center exhibited chlorinated solvent impacts from four different source areas of varying ages.
To sort out the complexities of multiple sources with multiple responsible parties, Aspect hydrogeologists distinguished the relative solvent contribution from each historical source and developed a site conceptual model that was used to reach an equitable cost-sharing agreement. At the same time, our remediation engineers pilot tested an in situ chemical oxidation system for groundwater treatment without disruption to the active retail facility.
The final remediation system treats all source areas through one air sparge and soil vapor extraction (AS/SVE) system consisting of 16 soil-vapor extraction wells and 47 air-sparging wells spread over an acre of the property.
