The facility achieved a "Remedy Construction Complete" determination on September 29, 2015. The metal hydroxide sludge cell has been capped to mitigate the risk of human exposures to the hazardous material left in situ. Groundwater quality samples have been regularly collected by responsible parties to ensure that any impacts to groundwater remain at acceptable levels.
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.

For definitions of the terms used, hover over or click on the term.
This facility is a municipal landfill that formerly maintained a metal hydroxide sludge cell, which received material from local industries. The sludge cell received approximately 4 million pounds of sludge from lime treatment of spent pickle liquor and wastewater operations.
This approximately 101 acre facility is located in an industrial area of Wallingford, 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.
