Recently Awarded: Two New Projects

Sierra West recently won a contract with the Bureau of Reclamation (Bureau) to address petroleum hydrocarbon impacts to soil and groundwater along the shore of Lake Berryessa, California. Sierra West and the Bureau are working with the Central Valley Regional Water Quality Control Board to conduct bench-scale laboratory tests to understand the degradation rates in groundwater under limited oxygen conditions. The results will be used to implement a field pilot test using air injection/pneumatic fracturing and soil vapor extraction. Completing the work will provide a foundation for a full-scale final remedy for the Site.

Sierra West also received authorization to assist a local water agency with their water treatment needs. Recently lowered hexavalent chromium water quality standards have rendered many water supply sources out of compliance. Sierra West will evaluate well improvements and water treatment technologies to meet the new drinking water standards. In addition, Sierra West will assist with grant funding opportunities.
