Project Description

Project management included design and installation of chemical oxidation (CO) and soil vapor extraction (SVE) systems to reduce soil and groundwater contaminants to concentrations below risk-based concentrations (RBCs) for applicable receptors and exposure pathways. The project is ongoing and has been implemented in two (2) phases. Phase I targeted remediation of gasoline-range total petroleum hydrocarbons (TPH) in soil and groundwater beneath, and adjacent to, the footprint of the on-site building.

Project Description

The project site is a retail service station facility located in Veneta, Oregon. Below-ground releases of gasoline at the subject property dating back to 1979 resulted in on-site and off-site soil and groundwater impact beneath a broad area.

In 1991, two (2) independently operated groundwater pump-and-treat systems were installed to process groundwater impacted by the release and control plume migration.
