Our project experience includes environmental engineering services for the aerospace industry which includes remediation of former aerospace sites that pre-date World War II (also called legacy sites), and several CERCLA sites located in Southern California.
When seven production wells operated by a Southern California water purveyor reported concentrations of hexavalent chromium and perchlorate above regulatory limits for drinking water, a multiagency effort was conducted to identify sources of chemicals of concern.
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.
Description of the Biological Reduction Process Biological treatment is used in a wide range of water and wastewater treatment applications for the removal of biodegradable constituents. The biological treatment process can also be modified and used to reduce nitrates, oxides … Continue reading
