NPL Site Narrative for Pike and Mulberry Streets PCE Plume
PIKE AND MULBERRY STREETS PCE PLUME
The Pike and Mulberry Streets PCE Plume is located in Martinsville, Indiana.
The Pike and Mulberry Streets PCE Plume was discovered from investigations conducted at the nearby Master Wear facility, a former drycleaner that released chlorinated solvents to the soil and ground water during its operations from 1986 to 1991. Potentially responsible parties for the Master Wear facility have conducted a removal action at the site with the EPA's oversight. Tetrachloroethylene (PCE) has been found in the city's drinking water supply and levels have continued to increase. The Master Wear facility is a possible contributor to the plume and there appear to be other possible sources of PCE contamination in the Martinsville area that may be contributing to the plume contamination.
The ground water plume consists of the chlorinated solvents PCE, trichloroethene (TCE) and cis-1,2-dichloroethene (cis-1,2-DCE).
Potential Impacts on Surrounding Community/Environment:
The ground water plume has contaminated one of the Martinsville municipal drinking water wells. This well, serving about 5,000 people, was found to contain elevated levels of PCE above the EPA's Safe Drinking Water Act Maximum Contaminant Level (MCL). The water from the municipal wells is currently the sole source of drinking water for the residents of Martinsville. While Martinsville operates an activated carbon filtration system to remove PCE from its water, PCE remains in one of Martinsville's municipal wells and in several monitoring wells, posing a potential risk to the community.
Response Activities (to date):
A potentially responsible party (PRP) removal action, conducted under the EPA's oversight, was initiated in August 2004 and completed in December 2008 at the Master Wear facility to address contaminated soil. Although the Superfund removal action objectives were met, PCE levels exceed the MCL and are increasing in ground water. Due to the presence of PCE in the wellfield, the city of Martinsville installed an activated carbon filtration system in June 2005 to remove PCE from its drinking water.
Need for NPL Listing:
The risk to the community remains high due to rising levels of PCE in one of the Martinsville municipal wells and in several monitoring wells. NPL listing would allow for investigation of the nature and extent of the contamination of the possible sources, and enable the EPA to determine cleanup alternatives for the contaminated areas. Other federal and state cleanup programs were evaluated, but are not viable at this time. The EPA received a letter of support for placing the site on the NPL from the state of Indiana.
[The description of the site (release) is based on information available at the time the site was evaluated with the HRS. The description may change as additional information is gathered on the sources and extent of contamination. See 56 FR 5600, February 11, 1991, or subsequent FR notices.]
