Site Status
- The fourth Five-year Review of the Bendix Site was completed in August 2012. This review determined that the remedy is protective in the short-term but several issues must be addressed in order for the Site to be protective in the long-term.
- Issues identified in the 2012 Five-Year Review included 1) remaining sources of Site contaminants in soil and groundwater, 2) potential gaps in the on-site groundwater containment system, and 3) lack of cleanup criteria for several Site contaminants. EPA and the Pennsylvania Department of Environmental Protection are working with the responsible party for the Site to address these issues.
- A Supplemental Site Investigation (SSI) was started 2009 to identify remaining sources of groundwater contamination. A second phase of the SSI was conducted in 2011 and a third phase is planned in 2013 to address remaining data gaps.
- As a result of the investigation, several pilot studies were conducted during the summer of 2011 to evaluate various cleanup technologies. Study results will be used to select additional cleanup actions.
- A vapor intrusion (contaminants seeping into indoor air from soil and/or groundwater) study was conducted in several nearby homes in the spring of 2009, and the final report was completed in May 2011.
- The investigation concluded that a few site-related contaminants may be migrating into one or more nearby residences. However, there are also likely sources right within the homes contributing to most, if not all, of volatile chemicals picked up by the sampling.
- Evaluations of all the homes indicated that vapor intrusion does not present any unacceptable health risks to residents.
- A vapor intrusion study was also conducted in 2008 in the on-site building, and it was found that indoor air contaminants posed an unacceptable health risk to the workers in that building.
- As a result, the offices of two maintenance staff were moved to a new temporary building and the contaminated building is no longer being used.
Background
- The 60-acre Bendix site is located in South Montrose just east of Route 29 in Bridgewater Township.
- The site consists of a closed manufacturing building and office, a parking lot, two treatment buildings and fenced grounds.
- The site was used to manufacture aircraft instruments from 1952 to 1996, when industrial solvent waste was disposed of in a lagoon and a series of trenches.
- In addition, from the 1950s to 1978, oil-contaminated water was also disposed of in a pit, but these liquids were eventually drained and the pit was backfilled and seeded.
- Investigations from 1984 to 1987 showed soil and groundwater contamination.
Cleanup History
NPL Listing History
| Status: | Listed: 1987 |
| Deleted: |
- The groundwater treatment system was completed in 1992.
- The monitoring well system was completed in 1994.
- Cleanup of contaminated soils was completed in 1995.
- Additional monitoring wells were completed in 1996.
- A new sump was built to collect groundwater on the eastern side of the site in 1999.
- Monitoring of surface water, groundwater and residential wells is ongoing, as is groundwater treatment.
- The 2007 Five-Year Review of the site, which was done to ensure that all the cleanup actions continued to protect the community, recommended that additional evaluations be done of the groundwater remedy, vapor intrusion, and institutional controls.
- As a result, 1) the vapor intrusion study was done in the on-site building and in residential homes; 2) institutional controls were put in place restricting use of the site; and 3) the supplemental site investigations were done to trace ongoing sources of groundwater contamination.
Contaminants and Risks
- Volatile organic compounds (VOCs), especially trichloroethene (TCE), which are the major components of solvents, have been found in the groundwater, surface water and sols at the site.
- Low levels of VOCs have been detected in off-site private wells, and as a result, these wells have treatment systems to remove the contaminants.
- The groundwater on-site, if consumed, could pose a health risk.
- Contaminant descriptions and associated risk factors are available from the Agency for Toxic Substances and Disease Registry, the environmental arm of the CDC.
