    Listing:
    On September 11, 2010 DEP facilitated the future
    Remedial Response action(s) as defined in HSCA by placing the Site to Pennsylvania’s Priority List of Hazardous Sites for Remedial Response (“PAPL”)


    Remedial Response Action

    • The Site consists of areas of groundwater, soil, and surface water contamination. Groundwater contamination at the Site affects certain properties located along South Malin Road, Lancaster Avenue (US Rt. 30), Conestoga Road (PA Rt. 401), Morehall Road (PA Rt. 29), and Village Way.

    • The known sources of the contaminated groundwater and surface water and areas of contaminated soil are located on the former Bishop Tube property ("Source Property"), currently owned by CDP.

    • DEP's responsibility under the Hazardous Sites Cleanup Act ("HSCA") is to select a remedy that is protective of human health and the environment and complies with all statutory and regulatory requirements.

    • In September 2022, DEP selected a remedial response action to address soil, groundwater, surface water, and a residential drinking water supply.
    • DEP plans to remediate the Site to a combination of residential Act 2 standards, based on the anticipated end use of the Source Property. DEP divided the Site into three operable units ("OUs"). The selected remedy includes
      • Operable Unit 1 (OU1) - In Situ Chemical Oxidation and/or In Situ Chemical Reduction (PDF) ("ISCO/ISCR"), coupled with soil mixing to address unsaturated and saturated soils impacted by Site contaminants of concern ("COCs");
      • Operable Unit 2 (OU2) - In situ injection of ISCO, ISCR or bioremediation amendments in the two primary chlorinated solvent source areas to address contaminated groundwater with engineering, and/or institutional controls, and long-term monitoring; and
      • Operable Unit 3 (OU3) connection of the residence with an impacted domestic well to the existing public water line.
    • The total estimated present value cost of the final remedial response action is $8.1M.


    Administrative Record


    What's Next

    • Planning for additional pre-design investigation activities.


    Pre-Design Investigations

    • August 24, 2021 - Soil Investigation for Certain Inorganic Constituents and Groundwater Investigation for VOCs and Certain Inorganic Constituents (PDF) Submitted by Roux Associates, Inc. on behalf of Johnson Matthey, Inc. and Whittaker to report results of soil sampling completed in May 2021 and groundwater sampling performed in June 2021. (This document was included in Part II of the Administrative Record for the Site but was not considered during preparation of the AOA.) Soil sampling was conducted to follow up prior detections of inorganic parameters and groundwater sampling was performed to evaluate VOC concentrations across the site area.

    • January 28, 2022 - Recent Regulatory Updates and Laboratory Data Package Correction (PDF) - Submitted by Roux Associates, Inc. on behalf of Johnson Matthey Inc. and Whittaker to acknowledge updates to Pennsylvania Code, Title 25, Chapters 93 and 250 and to provide updated laboratory analytical data for a soil sample collected in May 2021. The update resulted from an internal audit performed by Roux’s analytical subcontractor.

    • April 1, 2022 - PFAS Sampling Results (PDF) – Sampling of per- and polyfluoroalkyl substances (“PFAS”) conducted by Roux Associates, Inc. on behalf of Johnson Matthey Inc. and Whittaker.
