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 and restoration are 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 for the next few months.
- Restoration of the boardwalk at the base of Silver Lake is nearly complete.
- Excavation activities at the FMP 7 Foster Avenue subunit are complete and restoration is underway.
- A soil vapor extraction system has been installed in the 1 Foster Avenue parking lot and will be operated and maintained through October 2026.
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.
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.
- Sherwin-Williams is implementing an extensive pre-design soil sampling project along the Hilliards Creek corridor between West Clementon Road and Hilliards Road beginning August 10 and continuing through early 2027.
- The project team will be conducting a Cultural Resource Survey along the Hilliards Creek corridor from Hilliards Road to Kirkwood Lake the week of August 17, 2026.
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.
