The White Swan Cleaners/Sun Cleaners Area Groundwater Contamination site (aka Magnolia Avenue Groundwater Contamination site) is an area of groundwater contaminated with dry cleaning chemicals and/or their breakdown products, perchloroethylene (PCE), trichloroethene (TCE) and cis-1, 2-dichloroethylene (cis-1,2-DCE) in portions of three municipalities: Wall Township, Manasquan Borough, and Sea Girt Borough, New Jersey. The shallow, unconfined Kirkwood aquifer was contaminated by two different dry cleaning facilities, the former White Swan Laundry and Cleaners located at 1322 Sea Girt Avenue and the former Sun Cleaners, located at 2213 Route 35 (aka 201 Manasquan Circle) in Wall Township. The Sun Cleaners property is located approximately 0.3 miles southwest of the White Swan property. The two dry cleaners contributed the same volatile organic contaminants to the shallow, permeable, sandy aquifer. The plumes have commingled and are heading east towards the Atlantic Ocean. The facilities operated from approximately 1960 to 1991. Other potential sources of contamination may be identified during the Remedial Investigation, which began in the winter of 2007. In 1995 and 1996 Phase I and II site assessments conducted at the Sun Cleaners location discovered PCE contamination at levels up to 7,400 milligrams per kilogram, (mg/kg) in the subsurface soils and PCE up to 200,000 micrograms per liter (ug/L) in the groundwater. In August of 1997, a resident on Magnolia Avenue in Wall Township informed the Monmouth County Health Department (MCHD) that groundwater samples from his shallow irrigation well had PCE at levels up to 1,546 parts per billion (ppb). MCHD responded by resampling his well, along with 6 others and found PCE at levels up to 595 ppb. The New Jersey Department of Environmental Protection (NJDEP) determined the Sea Girt municipal wells were at risk and sampled them on a monthly basis beginning in August 1999. In September 1999 PCE was detected in one of them at a level of 0.54 ppb. In 1999 NJDEP and MCHD initiated a groundwater investigation to identify the responsible parties. They identified White Swan Laundry and Cleaners as another potential source and they also delineated a groundwater contaminant plume 2.0 miles long and one mile wide that extended to the east. NJDEP sampled the indoor air of residential and commercial buildings in the vicinity of the White Swan site and found PCE and TCE at levels above the health based risk level. The case was referred to EPA in December 2001. EPA and NJDEP investigated hundreds of homes in the downgradient area and identified 28 homes that required “radon-like” air ventilation systems to effectively remove the contamination from the buildings. In April 2003, NJDEP produced a report showing widespread PCE and TCE contamination from Manasquan Circle (route 35) east to the Atlantic Ocean. PCE was also found in the surface water stream east of the circle at levels of 996 ppb which was coming from the underlying shallow aquifer.
