DEP Files Remediation Plan For Bishop Tube Site In Chester County

Update since 4/8/2022: 

DEP Files Remediation Plan for Bishop Tube Site in Chester County ( 

  • DEP has filed a Statement of Decision (SOD) and a Response to Public Comments (RTC) (see Part 1, Part 2 & Appendices) pursuant to the requirements of the Hazardous Sites Cleanup Act for the response at the Bishop Tube Site.  
  • DEP’s selected remedy includes In Situ, or ”in place,” Chemical Oxidation and/or In Situ Chemical Reduction (“ISCO/ISCR”), coupled with soil mixing to address impacted soils.  In Situ Chemical Reduction (“ISCR”)/In Situ Chemical Oxidation (“ISCO”) uses chemical reactions to destroy contaminants.  Contaminated groundwater in primary chlorinated solvent source areas will be addressed through in situ injection of ISCO, ISCR or bioremediation reagents.  Engineering controls, institutional controls (such as deed notices, prohibition of use of existing wells, or restrictions on installing new supply wells), and long-term monitoring will also be required.  The impacted domestic residential well will be connected to an existing drinking water line.  For more information on the remediation technologies please visit:
  • The Administrative Record is available electronically for review on DEP’s webpage for the Site: or by following this link directly: Bishop Tube Administrative Record.
  • DEP will host a public meeting about the implementation of the response action on a date to be determined in the coming months.
  • Additional information will be provided in future community updates.
