The EPA reports that it has finalized its cleanup plan for the White Swan Cleaners/Sun Cleaners Superfund Site in Wall Township, Manasquan Borough, and Sea Girt, New Jersey.
Extensive contamination of soil and groundwater exists due to dry-cleaning activities that took place between 1960 and 1991. Soil and ground water is contaminated with volatile organic compounds, such as PCE and TCE. Vapors have intruded into 34 residential and commercial buildings in the area. In order to deal with these vapor intrusions, the EPA has implemented mitigation systems in these buildings to vent the vapors, and monitors buildings in the area on an ongoing basis for unacceptable levels of TCE or PCE vapors.
Cleanup of the site is expected to cost about $19 million. Roughly 5,000 cubic yards of soil will be excavated, disposed of properly, and replaced with clean fill. A soil vapor extraction treatment system will also be used, as will air sparging, and groundwater treatment processes.
More information about the site and the cleanup processes is available in the EPA News Release.
