At thousands of sites worldwide, chlorinated solvent spills have contaminated groundwater, forming plumes migrating offsite to impact adjacent properties, threaten drinking water wells, enter streams, or cast-off toxic vapors intruding neighborhood homes. These sites range from dry cleaners and industrial manufacturers to landfills and Superfund sites.
The treatment objective at sites impacted with chlorinated volatile organic compounds (CVOCs) often involves stopping or preventing a CVOC plume from moving offsite. However, there are limited practical, cost-effective remedies that have achieved this goal over the long term.
