SVE is an in-situ remediation technology designed to remediate soils impacted with VOC’s including gasoline range organics, and chlorinated hydrocarbons. This technology works by extracting a soil vapor from the subsurface at a high vacuum and remediate soil in the vadose zone.
Feasibility Study, Sugar Mill Wastewater Treatment, Nicaragua Sugar Estates Limited (Ingenio San Antonio), Central America
After the Nicaraguan government published new wastewater discharge regulations, a Nicaraguan Sugar Mill was required to select a new wastewater treatment plant. A feasibility study consisting of a wastewater characterization program and a feasibility study was conducted to identify the most cost-effective technology for wastewater treatment.
A chemical metering system used for chemical precipitation of phosphorous required upgrading to accommodate a higher wastewater flow and phosphorous loading. A new chemical metering system consisting of ferric chloride storage tanks, pumps were designed, specified and constructed.
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
Two neighboring sites owned by the client were impacted with a plume of gasoline released by leaking underground storage tanks. To abate the problem, the client installed two groundwater treatment systems and a soil vapor extraction system. All systems were failing to operate or operated with substantial down-time.

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 … Continue reading
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.

The site is an active oil and natural gas production property that currently re-injects approximately 135,000 barrels per day (BPD) of produced water. As a result of limited reinjection capacity, the facility was required to treat and discharge up to … Continue reading
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.
To improve the performance of an existing water treatment plant, a sludge dewatering and anaerobic digesting system was designed and constructed. Continue reading
