Feasibility Study, Remediation of Oxygenate Impacted Groundwater, Retail Gas Station, California
A gas station located in Southern California had contaminated the groundwater with oxygenates. The client was in need to contain plume of MTBE and TBA, which was migrating to an environmentally sensitive area. A feasibility study evaluating nine remediation scenarios was conducted to identify the best remediation option. Continue reading

Treatment of Groundwater Impacted with 1,4-Dioxane, Westlake Village, California
The development plan for a former media manufacturing site impacted with volatile organic compounds (VOCs) and 1,4-Dioxane in groundwater included the construction of a large development in Westlake Village California. A feasibility study concluded that a pump-and treat system consisting of an advanced oxidation process combined with liquid phase activated carbon (LPGAC) was required. The follow-up work included preparing a detailed design, preparing NPDES permits for storm water discharge, process flow diagrams, layout diagrams, and process and instrumentation diagrams.

Bench Scale Testing of Advanced Oxidation for MTBE
The Merced County of Environmental Health office ordered a gas station located in Los Banos, California to mitigate a plume of MTBE. To mitigate the MTBE in groundwater, an advanced oxidation system was proposed for the site. A pilot test was performed to assess the impact of ozone on naturally occurring chromium in soil at the site.
