Please make a note.

Precision Plating Corporation is one of several tenants in a small industrial complex, known as the Hillside Industrial Park. Precision Plating Corp. has been chrome plating various metal parts and fixtures on this 3-acre site since 1970. The chrome plating process includes alkaline cleaning, chemical etching, rinsing, buffing, and polishing. Wastes generated during this process include rinse waters containing heavy metals, batch wastes of alkaline cleaner, and spent plating and etching acids. Before 1983, rinse waters were discharged to a storm drain outside the building. Process plating acids and chrome plating wastes were stored in drums and in a 500-gallon tank. In 1979, Vernon's Health Department found the well serving the Hillside Industrial Park to be contaminated with hexavalent and trivalent chromium. The rupturing of drums and a storage tank by a snow plow was the alleged cause of contamination. The company, and later EPA, confirmed that the groundwater underlying the site had become contaminated. The Site is bounded by a private residence to the north, a trailer park to the south, a large apartment complex to the east, and private residences and commercial establishments to the west. An estimated 10,800 people obtain drinking water from public and private wells located within 3 miles of the site. Surface waters in the area are used for recreational fishing. The site is located within 1 mile of a freshwater wetland.

Threats and Contaminants
[Back to Top]

Site groundwater and soil is contaminated primarily with hexavalent and trivalent chromium as a result historical waste discharges and a 1979 500 gallon tank spill of chromium contamination. A subsequent excavation of contaminated soil and leachfields reduced the direct contact exposure risk. While drinking water wells at an adjacent mobile home park have been connected to the municipal water supply, current sampling data indicate that other nearby private well supplies downgradient of the site have been impacted by waste disposal activites at the industrial complex. The site is located within 1 mile of a freshwater wetland.

Cleanup Approach
[Back to Top]

This site is being addressed in two stages: initial actions and a long-term remedial phase focusing on cleanup of the entire site.

Response Action Status
[Back to Top]

Initial Action Precision Plating complied with orders issued by the State in 1986 by installing five shallow monitoring wells, sampling surface water, removing 20 cubic yards of contaminated soil, and providing alternate drinking water supplies to a mobile home park to the south.

Entire Site The site was placed on the NPL in 1989 and an investigation into the nature and extent of contamination at the site began in October 2002 and was conducted under the authority of the CT DEP (currently the CTDEEP). An EPA Remedial Investigation/Feasibility Study (RI/FS) into current site conditions began in 2012 and is ongoing. While this site is currently a Federal lead site, EPA is working closely with the State of Connecticut on all aspects of the project.

Enforcement HighlightsIn 1986, the State issued orders requiring the installation of monitoring wells, the sampling of surface water, removing of contaminated soil, and providing alternate water to nearby affected residents. In 1998 EPA and CTDEP signed an Enforcement Agreement formally assigning the cleanup of the site to the State. In 2000, CTDEP issued a Consent Order to the property owner to investigate and remediate contamination at the site. A work plan for site characterization was approved by CTDEP in October 2002 and proceeded until 2011 when it was determined that this project would be transferred to EPA to complete the site characterization.

Environmental Progress
[Back to Top]

Immediate risks have been minimized by excavation and off-site disposal of contaminated soils to reduce the risk of direct exposure. Exposure risks to contaminated groundwater
have partially addressed by providing an alternate drinking water supply to nearby residents. However, not all private wells impacted by contaminated groundwater are connected to the municipal water supply.

Current Site Status
[Back to Top]

The RI/FS is ongoing in 2015. New groundwater monitoring wells were installed in the vicinity of the site and the first round of groundwater sampling was completed in the Spring of 2015. EPA's residential potable water sampling program has been in place since 2012. However, CTDEEP had a private well monitoring program in place prior to that. Data indicates that there are groundwater exposure risks. Site contamination will be addressed through a future EPA cleanup action.
