After a product pipeline was discovered to have impacted soils and groundwater Chevron Corporation relied on us to construct and operate a groundwater treatment system in Tracy, California. The system operated for 24 hour-a-day, and we remained onsite to provide day and night service. The system included thirty groundwater extraction wells with submersible electric pumps, conveyance piping, ten 20,000-gallon steel tanks, diesel transfer pumps, a 200-kilowatt generator, four 20,000 pound carbon vessels, and secondary containment berms. As part of the project, our staff received additional safety training to comply with Chevron standards. Water was treated and discharged according to cleanup standards and the pipeline was successfully repaired.
