Remedial Design and Pilot Testing, Costa Mesa, CA

Accord Engineering was retained by an oil refining company to conduct a feasibility study and prepare a remedial action plan for an active gas station site. The soil and groundwater was contaminated with petroleum hydrocarbon fuels. The following tasks were accomplished:



  • Remedial design and reporting
  • Field pilot testing
  • Groundwater monitoring well installation
  • Data collection and evaluation

In order to minimize the impact to business operations, our engineer conducted a 48-hour, dual-phase-extraction pilot test using a truck-mounted extraction and thermal oxidation system. Three groundwater wells were installed as testing wells and future monitoring wells. The test was successfully completed. Testing data were evaluated and a conceptual remedial design was prepared in the remedial action plan.
