California Regional Water Quality Control Board, Lahontan Region, 37 pp, 2018

In late 2010, perchlorate groundwater pollution was detected in a water supply well for the City of Barstow and Marine Corps Logistics Base Nebo. The perchlorate issue arose from illegal disposal of excess perchlorate salts by a defunct pyrotechnical company. Water Board staff recently obtained a $2.67 million grant to address cleanup at the perchlorate source area. The Water Board proposes to construct a pilot-scale soil flushing unit and up to three groundwater extraction wells in a system to capture, treat, and apply treated water to the perchlorate source area and flush perchlorate to groundwater for subsequent capture. Once the pilot-scale treatability study is complete, the Water Board will seek additional funding from the State Water Board for a long-term cleanup project to address the perchlorate source area as well as perchlorate groundwater pollution downgradient of its present location. The perchlorate plume (~2 miles long by 1000 ft wide) is adjacent to and likely commingled with a nitrate plume (~1.75 miles long by 2000 ft wide). To address nitrate and perchlorate in groundwater, the City of Barstow and its contractor applied for and received a $1.7 million dollar grant from the California Energy Commission to install a biofiltration system for contaminant removal. https://www.waterboards.ca.gov/lahontan/board_info/agenda/2018/jan/item_6_barstow.pdf
