Current Site Status
Construction of the remedy was completed in 1998. The U.S. Environmental Protection Agency (EPA) is overseeing the long-term maintenance of the site, including ongoing monitoring of groundwater. The site security system, the cap and the storm water management system are inspected quarterly. An annual inspection report is submitted to the EPA including photos and copies of the inspection reports.
In September 2011, EPA completed a Five-Year Review of the cleanup remedy at the Site. EPA is required to conduct this review to ensure that the remedy remains protective of human health and the environment. As required, a similar review will be conducted every five years. The review is the third such review at the Site. A copy of the final 5-Year Review Report, dated September 23,2011 is available on the Internet.
The assessment, by the 2011 five-year review, found that the Site remedy was constructed in accordance with the requirements of the Operable Unit (OU1) Record of Decision (ROD) and is functioning as designed. Stream corridor monitoring was conducted in compliance with the OU2 ROD. Treatment successfully reduced the levels of VOCs in the soil. The cap is effectively preventing direct contact with the contaminated soil that remains on-site. The cap is also preventing infiltration of rain water and therefore, is preventing future release of site-related contaminants to shallow groundwater. Capping, site restoration and revegetation are preventing the migration of contaminated soil to the on-site tributaries of Rapp Creek. The groundwater monitoring and the stream corridor monitoring confirm that the remedy objectives are being achieved.
The Five-Year Review noted that Institutional Controls were put in place to ensure that future uses do not adversely impact the effectiveness of the remedy. The Report did not find any issues, nor did it had any recommendations.
In 2012, RSC requested a reduction in the sampling frequency for groundwater at the Site. After another round of sampling in 2013 and the analysis of the previous 20 years of groundwater sampling, EPA has determined that it is safe to reduce the groundwater sampling frequency to once every five years. The groundwater sampling shall be done the year before the Five Year Review report is due in order to be available for the determination of the protectiveness statement of the report. Yearly Site inspection and sampling for surface water as well as for sediment will continue. No issues have been found during the sampling events. EPA is working toward issuing a Final Close-Out Report (FCOR).
Site DescriptionBACKGROUND: The 113-acre Revere Chemical Co. facility, located near Routes 611 and 412 in Pennsylvania, was an acid, metal, and plating waste processing operation also suspected of accepting organic solvent waste. While the plant operated, wastes containing chromic acid, copper sulfate, and other heavy metals, as well as sulfuric acid and ammonia, were stored on site in unlined earthen lagoons. A U.S. District Court ordered the facility to close in 1969 for causing contamination of a tributary of Rapp Creek. The company abandoned full and empty drums, waste-filled lagoons, and piles of solid waste. In 1970, the Pennsylvania Department of Health treated and removed 3 million gallons of liquid wastes. In the mid-80's about 520 people lived within a mile of the site, with the closest home being less than 1/4 mile away. Today there are at least 650 private wells within three miles of the site. The area surrounding the site includes recreational streams, forests, fields, and State game lands. The Delaware River is seven miles from the site and is a water supply source for Philadelphia.
Site ResponsibilityThis site is being addressed through a combination of federal, state, and potentially responsible parties' actions.
NPL Listing HistoryOur country's most serious, uncontrolled, or abandoned hazardous waste sites can be cleaned using federal money. To be eligible for federal cleanup money, a site must be put on the National Priorities List. This site was proposed to the list on September 18, 1985 and formally added to the list July 22, 1987.
Threats and ContaminantsSoils on the site were contaminated with benzoic acid, and heavy metals and volatile organic compounds (VOCs), the chemical components of solvents, and polycyclic aromatic hydrocarbons (PAHs), the by-products of petroleum. The surface water and sediments contain some of the metals detected in site soil contaminants. Potential health threats include accidental ingestion, dermal contact with contaminated soils, and inhalation of dust from contaminated soils. The shallow groundwater has been found to contain VOCs.
Contaminant descriptions and risk factors are available from the Agency for Toxic Substances and Disease Registry, an arm of the CDC.
In 1970-71, the Pennsylvania Department of Health consolidated drummed materials in the lagoons, treated them with lime, pumped out approximately 3,000,000 gallons of waste, and then removed them. About 1,000 empty drums were crushed and buried on site. In 1984, an EPA emergency team removed 22 drums of waste chromic acid and excavated 30 cubic yards of sludge containing copper and chromium. All materials were sent to an EPA-approved hazardous waste facility. In 1991 EPA ordered a group of those determined to be potentially responsible for the contamination known as potentially responsible parties (PRPs), to remove the crushed drums which were excavated during remedial investigation field work, and also required soil erosion and sedimentation control at the site.
A group of the PRPs, known as the Revere Steering Committee, is addressing contamination. The committee is comprised of the following companies: AT&T Corporation, Inc. (currently Lucent Technologies), AT&T Global Information Solutions, Inc. (currently NCR Corporation), Carpenter Technology Corporation, General Electric Company, GTE Operations Support Incorporated (as successor to the interests of GTE Products Corporation), International Business Machines Corporation, Square D Company (on behalf of Yates Industries), and Unisys Corporation.
Removal of solid waste & debris, and additional drum removal was completed in the Spring of 1996.
Remedial action work plans for the vacuum extraction and the pre-construction activities for the cap were submitted in April 1997. Field work for the vacuum extraction of the contaminated soil was completed in July 1997. The remedial action report was approved in September 1997. Phase I of the cap work was completed in September 1997. Phase II began in April 1998. All on-site construction was completed in October 1998 and was documented by the signing of the Preliminary Closeout Report on November 2, 1998. In December 2003, ownership of the property was transferred to Nockamixon Township. Institutional Controls in the form of a Declaration of Covenants, Conditions and Restrictions were recorded at the Bucks County Recorder of Deeds by the Township in April 2004. The Institutional Controls were updated with an Environmental Covenant that was recorded at the Bucks County Recorder in April of 2010.
