Perchlorate Groundwater Investigation, Barstow, California
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.
