Site Closure Plan and Closure Strategy and Regulatory Support, Former Aerospace Site, Southern California
A soil vapor extraction system located at former aerospace site in Southern California had operated for a number of years. The client requested a strategy to obtain regulatory site closure. In response, a site closure plan was prepared outlining a schedule and a list of technical and administrative requirements to support site closure. The closure plan also listed methods and procedures to demonstrate that site-specific cleanup concentrations were protective of human health and groundwater.

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.

Biological Wastewater Treatment and Operations Training in Argentina
A wastewater treatment process at a potato processing plant located in Argentina was experiencing continuous upsets with their activated sludge treatment system. A hands-on training program was implemented to teach operators to monitor and control the two existing biological treatment processes consisting of a low rate anaerobic wastewater treatment pre-treatment and an activated sludge treatment system.

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.
