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) Soils Unit
Sherwin-Williams is implementing the EPA-approved pre-design investigation to address soil and light non-aqueous phase liquid (LNAPL) contamination at the FMP. For more information on the FMP unit and remedy, visit the FMP Soils page.
The pre-design LNAPL field investigation and a soil vapor extraction (SVE) pilot study began in February 2022 and is now substantially complete. Over the next year, bench-scale laboratory testing of various bioremediation nutrient alternatives will be performed. The information gathered during the field investigation, as well as the bench-scale testing results, will be analyzed and incorporated into the final design of the LNAPL remediation program.
Additional pre-design investigations related to historic soil contamination in the FMP areas began in March 2022 and will continue over the next several months.
Additional information and updates will be posted as the field work progresses.
United States Avenue Burn Site Unit
Remediation and restoration activities related to the United States Avenue Burn Site in Gibbsboro are expected to begin in late Summer 2022. USEPA is currently reviewing design documents and Sherwin-Williams is preparing for construction activities to begin this year.
Residential Properties Unit Update
Remediation and restoration activities are complete on all properties scheduled to be addressed under the Residential Properties unit.
Periodic inspection and maintenance of newly planted vegetation in regulated areas on completed properties will be performed over the next five years as required under the New Jersey DEP land use permits.
Route 561 Dump Site Unit
Remediation and restoration activities on all properties associated with the Route 561 Dump Site unit are complete. The staging area at 60 Berlin Road will continue to be used to store materials and equipment in preparation for remediation on the United States Avenue Burn Site in 2022.
Periodic inspection and maintenance of newly planted vegetation in regulated areas will be performed over the next five years as required under the New Jersey DEP land use permit. Groundwater associated with this unit will be monitored for the next several years.
