Phase I Environmental Site Assessment in Sayreville, NJ

Industrial and Commercial Heritage

Sayreville grew out of the Raritan River clay belt. James R. Sayre Jr. and Peter Fisher founded the Sayre and Fisher Brick Company on Main Street in the 1850s, and it became one of the largest brickmakers in the world, rising from 54 million bricks a year in 1878 to 178 million in 1913 and 6.2 billion cumulative by its 1950 centennial; the clay industry ran until 1970. DuPont began making gunpowder off Deerfield Road in 1898 and later added paint and photo products at the Parlin works on Cheesequake Road, with Hercules operating alongside it. The T. A. Gillespie shell loading plant in the Morgan section blew up in October 1918, killing dozens, damaging hundreds of buildings, forcing martial law, and scattering ordnance that still surfaces. National Lead ran a 418-acre pigment and paint complex on the river, and the Raritan River Railroad served Sayre and Fisher and the other plants by spur. That is an unusually heavy industrial inheritance for a borough of this size, and it shapes almost every Phase I ESA scope written here.

Current Environmental Profile

NJDEP Site Remediation Program records list 49 active known contaminated sites in Sayreville Borough, 21 of them carrying an ongoing Classification Exception Area for groundwater, including nine Category 2 and two Category 3 cases. Two federal Superfund sites sit inside the borough, the Horseshoe Road Superfund Site and the adjoining Atlantic Resources Corporation property at 120 Horseshoe Road, both with active CEAs. The contaminant profile runs heavier than a typical suburban market: heavy metals, PCBs, and radiological material from pigment manufacturing at the former National Lead property; explosives and propellant residues plus unexploded ordnance in the Morgan and Gillespie areas; chlorinated solvents from the DuPont, Hercules, Quigley, and Celotex operations; petroleum from the Route 9 and Route 35 service station corridor, which accounts for 37 of the 49 listings; and documented public-supply impacts at the Sayreville Water Department wellfield and the Scott Avenue groundwater case. Raritan River and Raritan Bay sediment quality and dredge material handling at the Disch Confined Disposal Facility are recurring considerations.

Real Estate and Development Market

Sayreville holds the largest brownfield redevelopment project in New Jersey history. Riverton, on the 418-acre former National Lead property, moved through a remediation effort of more than 120 million dollars over roughly 15 years, including 20 million dollars in Hazardous Discharge Site Remediation Fund grants that leveraged about 100 million in private capital, and it carries a 400 million dollar NJEDA Aspire award toward a 2.5 billion dollar build-out of roughly 6.5 million square feet, about 2,000 residential units, 1.3 million square feet of retail and entertainment, and 2 million square feet of office and commercial space. The property is part of the Sayreville Waterfront Brownfield Development Area. Smaller pipelines of work run through Sayreville Economic Redevelopment Agency parcels on Chevalier Avenue, Fulton's Landing on Main Street, and the River Road power generation corridor, and transaction volume spills into South Amboy, Old Bridge, East Brunswick, South River, Perth Amboy, and Woodbridge.

Local Regulators, Authorities, and Stakeholders

The NJDEP Central Regional Office in Trenton provides Site Remediation Program oversight for Middlesex County. Routine touchpoints during Phase II and remedial action work include the Sayreville Economic Redevelopment Agency, the Middlesex County Utilities Authority, the Middlesex County Office of Planning, the Freehold Soil Conservation District, and the borough engineer. Sites on the Raritan River, the South River, Cheesequake Creek, or the Raritan Bay shoreline typically require coordination with the NJDEP Division of Land Resource Protection on waterfront development, flood hazard, and CAFRA permitting, and with the Division of Water Quality. Work in the Morgan and Gillespie areas can also involve the US Army Corps of Engineers on munitions response, and redevelopment approvals run through the Sayreville planning board and zoning board of adjustment.

Why This Local Context Matters for Your Project

Local industrial history, the current contaminant profile, regulator office assignments, and real estate transaction velocity all feed directly into Phase I scoping decisions and downstream remediation planning. Sayreville is the kind of market where a generic database review is not enough: RCC crews know which parcels sit on former clay pits and brickyard fill, where the ordnance and propellant history changes a sampling plan, and how Central Regional Office reviewers and Middlesex County agencies actually run a file.
