Construction Update

The Sherwin-Williams project team is implementing the EPA-selected remedies for the Former Manufacturing Plant, United States Avenue Burn Site, Residential Properties, and Route 561 Dump Site units located in Gibbsboro and Voorhees.

Former Manufacturing Plant (FMP)

Sherwin-Williams is performing pre-design investigation, remedial design and remediation activities to address soil and light non-aqueous phase liquid (LNAPL) contamination at the FMP. For more information on the FMP unit and the EPA-approved remedy, visit the FMP Soils page.

• Sherwin-Williams is preparing for the upcoming remediation of the FMP U.S. Avenue South subunit, located southwest of the 1 Foster Avenue warehouse building. Actual remediation is not expected to start until this summer – pending receipt of all permits – and will continue for approximately six (6) months.
• Remediation is complete, and restoration activities are underway on the Former Manufacturing Main Plant (Paint Works) area at the base of Silver Lake. The project includes the following activities:
  • Restoration of the culvert beneath Foster Avenue
  • Soil grading, site restoration, and paving activities.
  • Foster Avenue will remain closed to thru traffic through July 2025. Access will be maintained for businesses and the Police Station.
  • Continued closure of the Paint Works parking lot to public use
  • Continued closure of the wooden boardwalk at the base of the Silver Lake

Sanitary Sewer Extension

The Sherwin-Williams Company is installing sanitary sewers in the roadways adjacent to the Former Manufacturing Plant and will connect residential properties on United States Avenue currently unserved by sanitary sewers.

• The first phase of work is complete. The remaining phases of sewer work will require periodic lane closures. Traffic modifications will be clearly marked.
• Construction is expected to continue into this summer.
• Work will generally be performed on weekdays between 7:00 a.m. and 5:30 p.m.
• Air monitoring under an EPA-approved community air monitoring program will be in place during construction activities

Waterbodies Unit

Sherwin-Williams is performing pre-design investigation, remedial design and remediation activities to address contamination in Silver Lake, Bridgewood Lake, Kirkwood Lake and the Hilliards Creek floodplain. Periodic field activities may occur within the lakes as the pre-design and remedial design phases move forward.
