EPA RCRA ID: CTD001168533
The Resource Conservation and Recovery Act (RCRA) is the public law that creates the framework for the proper management of hazardous and non-hazardous solid waste. Corrective action is a requirement under RCRA that facilities that treat, store or dispose of hazardous wastes, or did so in the past, investigate and clean up hazardous releases into soil, groundwater, surface water and air. For more information, and for more information on RCRA-specific terms used on this page, please visit EPA’s umbrella RCRA web page or EPA’s RCRA Corrective Action page.

This facility achieved a "Remedy Construction Complete" determination on September 30, 2019. Many areas of contaminated soil have been excavated and disposed of off site. A subsurface barrier wall was installed to prevent the migration of contaminated groundwater from beneath the site into nearby water bodies. A pump and treat system was installed to further address contamination in groundwater. Other areas of contamination were treated via in-situ thermal remediation. Contaminated sediments in adjacent water bodies were removed, and certain areas containing contaminated sludge, as well as additional soils, were capped in situ.
Cleanup Actions or environmental indicators characterizing the entire facility are shown below. This listing, and all the data on this page, come from EPA’s RCRAInfo and are refreshed nightly to this page. For this table, a blank in the Status column could mean the action either has not occurred or has not been reported in RCRAInfo.

Industrial operations at this facility began with the manufacture of electrical components in the 1930s, and industrial chemicals following Word War II. The Upjohn Company acquired the property in 1962 and, until 1993, continued the manufacture of specialty chemicals used in dyes and pigments; photographic chemicals; sunscreen agents; additives for soaps, perfumes and cosmetics; agricultural herbicides; pharmaceuticals; and photo-inhibitors. On-site operations included chemical mixing, treatment, and manufacturing, which generated wastes including spent solvents and unused commercial chemicals. Wastes were formerly managed in several RCRA units on site, including a waste container storage area, a storage tank, a waste pile system, and a surface impoundment.
This approximately 80 acre facility is located in an industrial area of North Haven, CT. According to the US Geological Survey's National Hydrography Dataset, this facility is located in the Quinnipiac River watershed and the nearest fresh surface water body is located on or immediately adjacent to the property. Geology in this area has been observed to be dominated by arkose and conglomerate formations.
Institutional and Engineering Controls help ensure human exposure and groundwater migration are under control at a cleanup facility. Where control types have been reported by states and EPA in EPA’s RCRAInfo, they are shown below. Not all control types are needed at all facilities, and some facilities do not require any controls. Where there are blanks, the control types may not be needed, may not be in place, or may not be reported in RCRAInfo.
