EPA in Indiana

Amphenol/Franklin Power Products in Franklin, Ind.

On this page:


Background

Franklin Power Products, Inc. and Amphenol Corp. conducted an environmental investigation and cleanup at their former Franklin, Ind. industrial facility under two Administrative Consent Orders issued by EPA’s RCRA Corrective Action program in 1990 and 1998.

EPA determined that a former owner and operator, Bendix Corp., released volatile organic compounds and other chemicals into the environment, including into on-site sewers which transported the contamination outside the property boundaries to the neighborhood south of the facility, prior to 1983.

The EPA’s orders required Franklin Power Products and Amphenol to investigate the releases of VOCs, including known carcinogens, to determine what was released and where it may have travelled, and to determine the potential health risks and environmental effects of the contamination. A sewer line found to be contaminated was replaced and contaminated soil was removed from a source area on-site. EPA also required the companies to construct and operate clean-up measures, including a groundwater pump-and-treat system, which has been in operation since 1995. EPA continues to oversee performance of this cleanup.

A non-NPL State of Indiana led Superfund site, Webb Well Field, is located about ¾-mile from the Amphenol site. Both sites are in Johnson County. The former municipal water well field was found to be contaminated with volatile organics and the contaminated wells were taken off-line by 2007; the final well was decommissioned in 2013. In 2007, Amphenol investigated possible contaminated groundwater migration of VOCs from its site to the Webb Well Field. Amphenol provided a groundwater particle tracking study to EPA to demonstrate that the VOC contamination found in the two impacted supply wells did not come from its facility.

Update

EPA will join Indiana Department of Environmental Management, Indiana Department of Public Health and the federal Agency for Toxic Substances and Disease Registry at an Aug. 3 public meeting in Franklin, Ind. The meeting will start at 6 p.m. in the high school.

Recently, Edison Wetlands Association and the “If It Was Your Child” organization raised concerns to EPA and IDEM about volatile organic compounds seeping into homes near the Amphenol/Franklin Power Products and Webb Well Field sites in Franklin. EPA will require that Amphenol Corp. investigate groundwater conditions and complete a comprehensive investigation of “vapor Intrusion” in the residential area near the site. EPA will oversee the investigation. EPA is coordinating closely with the State of Indiana and federal Agency for Toxic Substances and Disease Registry and will follow up with the community as more information becomes available.

Edison Wetlands Association also raised concerns about the potential for intrusion of radon gas at homes in Franklin. Radon is naturally occurring. Exposure to radon can result in adverse health effects. Residents can hire an Indiana-licensed professional to test their homes for radon and install a mitigation system if needed.

Air Sampling Update

  • Under supervision by EPA and IDEM, Amphenol collected 8-hour ambient (outdoor) air samples from six locations around the boundary of its site on July 26. A laboratory analyzed the samples and an independent data validation company has checked the results.  These samples were analyzed for the nine volatile organic compound (VOC) chemicals associated with the historic releases from the former Amphenol site.  Results at the fence line indicated that outdoor air concentrations of VOCs are below EPA’s health-based screening levels for residential exposure.
  • The emissions pipe at the groundwater recovery air stripping system was also sampled. Emissions were measured at a rate of approximately 8 pounds total VOCs per year. To put this in perspective, IDEM would issue an air permit for this system only if the air emissions reached at least 2,000 pounds per year.
  • On August 3, Amphenol installed a filter (vapor carbon system) on the emissions pipe to virtually eliminate its VOC emissions.
