Perchlorate Groundwater Investigation, Barstow, California
A Southern California regulatory agency suspected that illegal disposal of perchlorate had impacted the soil and groundwater of a residential property located in Barstow, California. A groundwater investigation project was conducted at a suspected source of perchlorate site, and extended 1.5 miles offsite. The groundwater investigation project fully delineated the extension of perchlorate impacted groundwater and identified remediation alternatives.

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.
