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.

  • Remediation activities are nearly complete at the FMP U.S. Avenue South subunit, and restoration activities are underway.
  • Remediation and restoration activities are substantially complete on the Former Manufacturing Main Plant (Paint Works) area at the base of Silver Lake.
    • A portion of the 2/4 Foster Avenue parking lot will continue to be used for soil management activities.
    • The boardwalk at the base of Silver Lake will be restored this spring.
  • Remediation activities at the FMP 7 Foster Avenue subunit are expected to begin the week of May 4, 2026.
  • A soil vapor extraction system has been installed in the 1 Foster Avenue parking lot and will operate for up to six months.

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 Sherwin-Williams team is implementing the final construction activities in the sewer expansion project.  This will require periodic lane and road closures and associated detours of Foster Avenue, as well as U.S. Avenue between Berlin Road and Egg Harbor Road. The detours will only be in effect during working hours.

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.

  • The remediation of Silver Lake is complete. The first phase of fish restocking will take place April 28, 2026, with additional fish stocking over the next year.
  • The Paint Works parking lot will be closed to public use until further notice.
  • Repairs and restoration to the wooden boardwalk will be completed before opening the area to the public.

Additional Field Activities

From time to time, the Sherwin-Williams team performs various field activities within each of the project units.

  • Sherwin-Williams performs periodic inspection and maintenance of newly planted vegetation in regulated areas for a minimum of five years following remediation and restoration as required under the applicable New Jersey DEP land use permits.
  • Groundwater sampling is performed on a periodic basis throughout the project area as required under applicable EPA work plans.

Contaminated soils are excavated, stabilized as needed, and trucked off-site to an EPA-approved landfill.

Excavation areas are backfilled and returned to pre-construction topography.
