- Evaluation and cleanup of the site is divided into three separate areas, or Operable Units: OU1 for contaminated ground water, OU2 for sources and contaminated soil, and OU3 for the intrusion of organic vapors from contaminated ground water (otherwise known as “vapor intrusion”) into the residence on the Boarhead Corporation property.
- Cleanup of OU1 is performed through an on-site ground water extraction system, comprised of a trench and extraction wells. A network of monitoring wells monitors performance of the system. Operation of the system is on-going.
- Cleanup of OU2 is complete. All known sources of ground water contamination, including drums, containers, and soil containing hazardous substances, have been removed.
- OU3 was recently created to address high concentrations of volatile organic compound (VOC) vapors, such as trichloroethene, or TCE, in the indoor air of the on-site residence. Cleanup work for OU3 is on-going and currently under evaluation. Concentrations of TCE have been reduced to levels that are protective in the short-term for the current population. Additional actions may be required to ensure long-term protectiveness to all populations, pending the outcome of the evaluation.
- Vapor intrusion for certain properties nearby the area of contaminated ground water at the site is evaluated annually as part of OU1 activities. No impacts to indoor air in any off-site residences has been observed to date or is anticipated to occur in the future.
- OU1 is currently being optimized to improve performance of the ground water extraction system. As part of optimization activities, Pond 11, the 4-acre pond on the Boarhead Corporation property, was permanently drawn down in summer 2014. Next steps are anticipated to include restoration to a wooded wetland habitat and expansion of the ground water extraction system into the former pond area.
- The cleanup of OU1 and OU2 is performed by groups of potentially responsible parties (PRPs) under consent decrees. Work related to OU3 is performed by EPA and the property owner.
- The most recent review of the remedial action, known as the Five-Year Review, was completed in September 2012. The review found that the remedial action for OU2 was protective of human health and the environment, but that the remedial action for OU1 was not due to the indoor air conditions at the on-site residence. Subsequently, OU3 was created to address this discrete portion of the site.
- The Boarhead Farms site is located on approximately 120 acres at 1310 Lonely Cottage Road in Bridgeton Township, Bucks County, Pennsylvania.
- In 1969, Mr. Manfred DeRewal, Sr. incorporated the Boarhead Corporation and purchased the two parcels that currently comprise the Site.
- Mr. DeRewal also oversaw operations at the Revere Chemical site, located about 4 miles from Boarhead Farms, from 1965 until 1969, when the Commonwealth of Pennsylvania ordered closure due to numerous pollution violations. In subsequent legal proceedings, Mr. DeRewal claimed that he moved 260,000 gallons of “liquid waste” from the Revere Chemical site to an unspecified location between July 17, 1970 and August 4, 1970.
- In the early 1970s, Pennsylvania State Police began receiving complaints of dead fish, dead plant life, and foaming in a stream adjacent to the Boarhead Farms site, allegedly due to acid dumped into the stream from tanker trucks.
- The Bucks County Department of Health reported a bulldozer at the Site burying drums during a subsequent investigation, in addition to observing pungent odors, empty tanker trucks, and approximately 40 drums containing unspecified solvents.
- Other inspections conducted in the early 1970s documented the improper storage of chemicals throughout the Boarhead Farms site, including leaks in 55-gallon drums, pools of chemicals along the access road, and uncontrolled wastes in containers.
- Known releases of chemicals from tanker trucks transported to the Site include 3,000 gallons of ferrous chloride in 1973, and 4,000 gallons of ammonia and 2,700 gallons of sulfuric acid in 1976.
- Other chemicals known to be brought to the Site by the Boarhead Corporation include copper ammonium sulfate, arsenic pentoxide, copper naphtholate, and unspecified solvents and pesticides.
- In October 1976, the Court of Common Pleas of Bucks County issued an order to Mr. DeRewal and Boarhead Corporation requiring the removal of chemicals from the Site and prohibiting chemicals from entering in amounts greater than necessary for normal household use.
- In 1984, EPA began conducting multimedia sampling as part of Site Inspection and subsequent Hazard Ranking System (HRS) activities.
- The Site was added to the National Priorities List (NPL) on March 31, 1989.
NPL Listing History
- EPA initiated a Remedial Investigation and Feasibility Study (RI/FS) in 1989 to delineate the nature and extent of contamination and develop and evaluate cleanup alternatives.
- Four removal actions were conducted by EPA in the 1990's to address the most serious threats.
- Over 2,500 drums and numerous tanker trucks were removed from the Site as part of the first two removal actions.
- Construction of the ground water collection and treatment system, installation of extraction wells and the interceptor trench, and installation of residential well treatment filters was conducted during the third removal action.
- General Ceramics, Inc. agreed to conduct the fourth removal action under EPA oversight to identify, excavate, and remove drums and soils contaminated with radioactive waste.
- EPA completed the RI/FS in 1997, and in 1998, presented the preferred cleanup alternative to the public for review and comment in the Proposed Plan.
- In November 1998, EPA issued a Record of Decision (ROD) which specified the technical details of the preferred cleanup alternative. The selected remedy included excavation and removal of remaining buried containers, aeration and treatment of contaminated soil “hot spots,” on-going ground water extraction and treatment, installation of additional monitoring wells, continued point-of-use treatment of residential wells, and studies to determine the applicability of phytoremediation.
- From July 2001 through May 2002, the OU1 PRPs conducted upgrades to the ground water extraction and treatment system outlined in the ROD, including air stripping for VOCs and precipitation for inorganic elements (metals). The system continues to collect and treat contaminated ground water.
- From April through September 2003, the OU2 PRPs conducted excavation and removal of drums and contaminated soils. A Preliminary Closeout Report (PCOR) indicating that the construction phase of the OU-2 remedy was complete was issued in November 2003.
- On April 15, 2009, EPA issued an Explanation of Significant Differences (ESD) lowering the cleanup goal for arsenic in ground water from 50 to 10 micrograms per liter (µg/L) and establishing a cleanup goal of 2 µg/L for vinyl chloride in ground water.
- Hazardous substances detected at the Site and subject to cleanup standards include numerous VOCs and metals.
- Ground water is the principal source of potable water in the vicinity of the Site. Treatment units employing granular activated carbon are present and maintained on all residential potable wells potentially at risk.
- Contaminant descriptions and associated risk factors are available at: (ATSDR web site).
