The Grants Chlorinated Solvents site is located in Grants, Cibola County, New Mexico. The site consists of a 20-acre, 100-foot-deep groundwater plume that extends about 1,000 feet from the source. An operating dry cleaning facility, no longer a source is the primary source of contamination. The primary chemicals contaminating groundwater include tetrachloroethylene (PCE) and its degradation products. Following remedy construction, operation and maintenance activities and groundwater monitoring are ongoing.

What Is Being Done to Clean Up the Site?

The site is being addressed through federal, state and potentially responsible party (PRP) actions.

EPA has conducted five-year reviews at the site. These reviews ensure that the remedies put in place protect public health and the environment, and function as intended by site decision documents. The most recent review concluded that response actions at the site are in accordance with the remedy selected by EPA and that the remedy continues to be protective of human health and the environment.

What Is the Current Site Status?

The site’s long-term remedy, selected in 2006, included vapor intrusion mitigation, thermal and chemical dechlorination technologies to address shallow and deep groundwater contamination, and institutional controls. EPA updated the remedy in 2011 to eliminate thermal treatment at the secondary source area due to low contaminant levels and to expand thermal treatment downgradient of the primary source into the shallow plume core. Enhanced reductive dechlorination also replaced the deep thermal treatment (from 40 to 80 feet below ground surface) in the primary source area. Remedy construction finished in September 2012. The thermal remedy treated about 33,000 cubic yards of contaminated soil. Operation and maintenance activities and groundwater monitoring are ongoing.

EPA’s Involvement at the Site

The Holiday Cleaners facility at 705 First Street is the primary source for the chlorinated solvent contamination at the site. Holiday Cleaners has operated as a dry cleaning business since 1969 under various owners. Most of the releases of chlorinated solvents occurred prior to 1988 when new equipment was installed. According to the current owner, releases at this source area are attributed to leaks from the old cleaning equipment and from delivery and overfill spills of the storage container in the rear of the building. The old equipment was removed from service and upgraded. The PCE storage tank is no longer in use.

An abandoned dry cleaner facility at 605 First Street is a secondary source of chlorinated solvents. A dry cleaning facility operated at this location from 1976 to 1977.
