Current Site Status
Construction at the Bendix Superfund Site was completed in 1996. Presently, contaminated groundwater continues to be collected and treated at the Site. There is also regular monitoring of the surface water, groundwater, and residential wells that will continue for many years.
EPA completed a five-year review of the Site to ensure that the clean-up remains protective of human health and the environment. As part of this review, EPA inspected the Site in May 2007. EPA also reviewed the groundwater monitoring data. EPA issued a five-year review report on September 28, 2007. EPA recommended that additional evaluations and appropriate follow-up actions be implemented on the groundwater remedy, vapor intrusion, and institutional controls. To follow-up on the five-year review, EPA in June 2008 issued an Explanation of Signifant Differences (ESD) to establish institutional controls for the site.
Site Description
The Bendix Superfund Site is located in South Montrose just east of Route 29 in Bridgewater Township, Pennsylvania. The Bendix Site consists of a 60-acre property including a closed manufacturing building and office, a parking lot, two treatment buildings, and grounds that are fenced. The Site lies between the Meshoppen Creek to the east and the Wyalusing Creek to the west. Residents in South Montrose rely on groundwater for their drinking water.
The Site was used to manufacture aircraft instruments from 1952 until 1996. From 1952 until 1958, industrial solvent wastes were disposed in a lagoon and also in a series of trenches. In addition, from the 1950s to 1978, a pit was used for the disposal of water-soluble cutting oil and oil-contaminated water from air compressors. These liquids were eventually drained from the basin, backfilled and seeded. Investigations from 1984 through 1987 showed contamination of soils from the disposal practices. The contaminants leached into the underlying groundwater.
Site Responsibility
Cleanup of this site is the responsibility of Federal and State governments, the site owner and parties potentially responsible for the site contamination.NPL Listing History
Our 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 on July 22, 1987.Threats and Contaminants
Volatile organic compounds (VOCs), primarily trichloroethene (TCE), have been identified in the groundwater, surface water, and soils at the site. Low levels of VOCs have also been detected in off-site private wells and, as a result, these wells have treatment. The groundwater on-site can pose a threat to human health if consumed.Contaminant descriptions and associated risk factors are available at: (ATSDR web site) http://www.atsdrcdc.gov/hazdat.htm
Cleanup Progress
All construction at the Site was completed in 1996. Design of the cleanup project began in 1990. Construction of the groundwater interceptor trench began in late 1991 and was completed in 1992. Groundwater collected in the trench is sent to the filter house for treatment by two activated carbon filters. Construction of a monitoring well system was completed in late 1994. Cleanup of contaminated soils was completed in the fall of 1995. Additional monitoring wells were completed in 1996. At present, all remedial construction is completed and contaminated groundwater continues to be collected and treated. Construction of the remedial activities was completed in 1996.
Homeowners near the Site with private wells are monitored twice a year and some properties have filters.
In 1998, levels of TCE above state standards were detected at a surface water discharge point. As a result, a new sump was built to collect groundwater on the eastern side of the Site. This groundwater is then pumped to the filter house for treatment. Construction of the new sump started in the winter of 1999 and was completed in the spring of 2000. EPA and PADEP conducted inspections during the construction. After the construction was completed, EPA and the PRPs collected water quality samples to evaluate the effectiveness of the new sump.
