The Iceland Coin Laundry Superfund Site (site) consists of the former Iceland Coin Laundry and Dry Cleaning facility (former facility), located at 1888 Delsea Drive in the City of Vineland, Cumberland County, New Jersey, and an area of contaminated ground water migrating to the south/southwest of the former facility. The contaminated ground water plume encompasses South Delsea Drive, Dirk Drive, Garrison Road, Lois Lane, South Orchard Road, West Elmer Road, and West Korff Drive.
The former facility operated from approximately 1953 to at least 1971. Limited information is available regarding waste disposal areas and systems. Four coin-operated dry cleaning units of eight pound-capacity were present at the laundromat, each using four gallons of tetrachloroethene (PCE). It is not known how often the PCE was refilled.
Two 14-foot deep seepage pits/cesspools with a 40-foot drain field between the pits were used beginning in 1962. According to the former owner, the cesspools were located in the front of the building. Septic system design drawings from 1963 indicated effluent from 10 washers discharged to a septic tank, and then continued to flow through a 100-foot field drain, and terminated at a 4-foot diameter receptor vessel. The facility was connected to the sanitary sewer in 1986.
From September 1987 to October 1990, ground water samples were collected on three occasions by the Vineland City Health Department (VCHD) from a well located at 1276 Garrison Road. Analytical results from these samples indicated the presence of volatile organic compounds (VOCs) above state and federal maximum contaminant levels (MCLs).
Between December 1990 and September 1991, the VCHD collected drinking water well samples from 55 residences in the area. Analytical results from these sampling activities indicated the presence of VOCs, primarily PCE, trichloroethylene (TCE) and 1,2 dichloroethylene (DCE), at concentrations above MCLs in 21 of the 55 residential samples. These 21 wells were estimated to serve approximately 44 people. Potable municipal wells which draws from the same aquifer system are located within 4 miles of the site, and serve approximately 28,770 people.
Site Responsibility: This site is being addressed through Federal and State actions.
What Has Been Done to Clean Up the Site?
The site is being addressed in two stages, immediate actions and long-term remedial phases focusing on cleanup of the site.
Immediate Actions: In November 1991, the NJDEP installed point of entry treatment (POET) units at the 21 affected residences as a temporary remedial measure. From April 1993 to July 1994 the VCHD extended the public water supply mains to the affected area. Service connections from the new mains to the residences were completed in early 1996. Subsequently, EPA identified and connected an additional four residences in 2012.
Long-term Response: The NJDEP conducted an expanded site investigation at the former facility. This investigation included subsurface soil and groundwater sampling.
EPA conducted an RI/FS at the site that found PCE and TCE in the ground water extending approximately 4,700 feet to the southwest. The central core of the plume was approximately 2,000 feet from the facility, sixty feet beneath the surface and contained PCE at a maximum level of 290 parts per billion (ppb). TCE was found at a maximum level of 17 ppb. The results of the investigation were used to evaluate a number of alternatives, including the more traditional and slower cleanup method in which ground water is pumped out and put through a treatment plant before re-injecting it into the ground. Subsequently, EPA conducted a treatability study where additives were injected into the ground water to break down hazardous chemicals into a form that are not harmful to people or the environment. This method removes the threat from remaining VOCs in the ground water. The results of the treatability study were used to design and implement a full scale treatment (bioremediation) barrier system. The bio-barrier and subsequent hot spot treatment injection activities are being monitored through periodic sampling events. Results are documented in performance reports.In 2002, EPA began conducting a Remedial Investigation and Feasibility Study (RI/FS) for the site. Following the completion of the RI/FS, EPA issued a Record of Decision (ROD) in September 2006. In-situ biological treatment was selected to remediate the PCE-contaminated groundwater plume. As part of the remedial design, EPA installed injection and monitoring wells, performed multiple rounds of bio-injection and when necessary, performed bioaugmentation between December 2006 and July 2007. The remedial design and well network installation was completed in September 2007. These results were used to develop a full scale bioremediation treatment method.
Between July and October 2011, EPA installed monitoring, extraction and injection wells on private properties along the intersection of Garrison Road and South Orchard Street to conduct bio-injection activities. Prior to amendment injection, a baseline sampling event to capture the current conditions of the contaminated groundwater was performed. This was followed by amendment solution (emulsified oil) injection into the subsurface to create a barrier wall that would reduce the tetrachloroethylene (PCE) contaminated groundwater plume as it migrated through the barrier. This bioremediation barrier was fully implemented by December 2011. Subsequently, additional amendment injection to treat hot spot areas was conducted during the summer of 2015. Periodic annual sampling has shown that the mass of the plume has decreased.
Six rounds of post injection sampling have been completed between April 2012 and November 2016.
Performance evaluation reports were submitted for each sampling event. A seventh round of bio-injection treatment sampling is scheduled for October/November 2017.
In August 2016, EPA submitted the Classification Exemption Area (CEA) application to the New Jersey Department of Environmental Protection (NJDEP) for approval. A CEA restricts the installation of potable and irrigation wells within a designated contaminated groundwater plume area.
A vapor intrusion assessment was conducted at the former Iceland Coin Laundry and Dry Cleaning facility building in the winter 2008, 2009, 2011, 2013 and 2014. No impact to the indoor air was identified. The next sampling event scheduled for 2018.
What Is the Current Site Status?
EPA continues to monitor the ground water plume following the recent bio-injection activities. Annual sampling is scheduled for the foreseeable future, and if necessary, additional bio- injection activities will be conducted.
Sampling and Monitoring
EPA will continue to perform annual performance monitoring of the groundwater plume.
