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.

Closure Plans for Contaminated Sites and Regulatory Closure Negotiations
Closure plans are prepared to supplement work plans for contaminated sites when a property owner is interested in obtaining No Further Action letters from the lead regulatory agency. Closure plans provide a description of administrative and technical requirements and factors supporting closure, including cleanup goals based on indoor vapor intrusion pathways and groundwater intrusion pathways. Communicating closure strategy is effective for early regulatory approval.
