Bishop Tube Development Proposal

The Bishop Tube Site is a former metals processing plant located in East Whiteland Township, PA.  The site is bordered by Little Valley Creek, a tributary to the exceptional value Valley Creek.   Portions of the site are wooded.  As a result of the historic uses at the site it has been designated as a Brownfields site. medium_thumb_IMG_0416_1024.jpg

Groundwater, soil and surface water at the Site are contaminated with TCE, which is classified as a probable human carcinogen by the EPA, and related products.  TCE is chlorinated solvent and one of the problematic volatile organic compounds (VOCs) identified at the site, first in 1987.  Chlorinated solvents are dense non-aqueous phase liquids, or DNAPLs.  They are denser than water and have a low solubility.  However, they are sufficiently soluble to cause a problem in both ground and surface water.  The EPA maximum contaminant level (MCL) for TCE is 0.005 mg/l, with a zero desirable concentration (, visited 2/18/17).  EPA lists it as a discharge from metal degreasing sites or other factories and that it causes liver problems and an increased risk of cancer (Id.).  Related compounds could include 1,1,1-trichloroethane and 1,1,2-trichloroethane (Id.).

Constitution Drive Partners, the current owner, is proposing a residential development (townhomes and apartments) at the site of the former Bishop Tube complex.  

The Delaware Riverkeeper Network is concerned that residential development of this site, as is being pursued and proposed, is highly inappropriate, will result in ongoing environmental and water contamination, and support continuing exposure pathways for community members.
