How NL Industries and 20 Corporate Co-Conspirators Poisoned a New Jersey Shoreline with Lead for Decades
For nearly half a century, battery manufacturers and metal smelters dumped lead-laced furnace slag onto a recreational shoreline bordering Raritan Bay. Wetlands were destroyed. Wildlife was poisoned. Residents were fenced away from their own beach.
NL Industries operated a lead smelting facility in Perth Amboy, New Jersey from 1928 to 1975, generating enormous quantities of toxic furnace slag and battery waste. Rather than disposing of this lead-contaminated material responsibly, NL hired a trucking company to dump it on the shore of Raritan Bay in Old Bridge Township and Sayreville. More than 20 battery manufacturers and metal companies sent their hazardous waste to NL’s facility, which compounded the contamination. The site now contains approximately 11,000 cubic yards of slag and battery casings, plus 80,000 cubic yards of lead-contaminated soil and sediment. The federal government has already spent over $32 million cleaning up this corporate mess, and the bill keeps growing. A residential neighborhood sits directly adjacent to a poisoned shoreline that residents were fenced off from in 2009 because public health officials confirmed it was simply too dangerous to swim, fish, or sunbathe there.
This is not an accident. This is a half-century of calculated decisions to treat a public shoreline as a private dumping ground. Demand full accountability for every corporation on this list.
| 01 | NL Industries purchased the United Lead Co. in 1928 and ran a secondary lead smelting operation in Perth Amboy, New Jersey, continuously until 1975, generating decades of toxic industrial waste. | high |
| 02 | NL’s smelting operations processed scrap batteries, scrap metal, lead oxides, and battery plates, producing furnace slag loaded with lead, chromium, antimony, and arsenic. | high |
| 03 | NL hired Liberty Trucking to dispose of its toxic waste. That waste was transported to a recreational shoreline area in Old Bridge Township and dumped directly onto land adjacent to Raritan Bay. | high |
| 04 | Around 1967, lead furnace slag and battery casings were dumped on the federally authorized Western Jetty at Cheesequake Creek Inlet, contaminating a public navigation structure and the surrounding waterfront. | high |
| 05 | More than 20 battery manufacturers and metal companies arranged to send their own hazardous waste to NL’s Perth Amboy facility. That waste was also ultimately dumped at the Raritan Bay site. | high |
| 06 | The site sits directly adjacent to residential properties. The contaminated shoreline, wetlands, seawall, and jetty were used by the community for recreation until federal authorities confirmed the area was a public health hazard. | high |
| 07 | Old Bridge Township purchased the contaminated seawall property in 1983 with documented knowledge that lead waste had been deposited there, yet the contamination was not addressed for decades. | med |
| 01 | The New Jersey Department of Health and the Agency for Toxic Substances and Disease Registry confirmed that the seawall, adjacent beach, and western jetty constitute a public health hazard due to elevated lead levels. | high |
| 02 | In 2009, EPA installed permanent fences around the beach, jetty, and wetlands and posted signs prohibiting swimming, fishing, and sunbathing at a recreational shoreline that a community depended on. | high |
| 03 | Lead, chromium, antimony, arsenic, and copper were identified in soils along the seawall, in sediments, and in surface water. These are not trace amounts; they are elevated above remediation thresholds. | high |
| 04 | Battery casings and furnace slag have produced confirmed adverse ecological effects on aquatic, terrestrial, and avian species. The contamination reached the bay itself, affecting the broader ecosystem. | high |
| 05 | Contamination in 2007 and 2008 sampling confirmed lead and heavy metal poisoning in soil, sediment, and surface water across multiple sectors of the site, years before any meaningful cleanup began. | med |
| 01 | The contaminated site sits in the Laurence Harbor section of Old Bridge Township, bordered by residential properties on three sides. Families living next to this site had no meaningful warning for decades. | high |
| 02 | The Margaret’s Creek Sector, a 47-acre wetland at the eastern end of the site, was contaminated with battery casings and furnace slag. Wetlands provide ecological services that cannot simply be replaced. | high |
| 03 | Residents and visitors were warned against swimming, fishing, and sunbathing at a shoreline on Raritan Bay that existed as a recreational resource for the Laurence Harbor community. | med |
| 04 | The site has been on the federal National Priorities List (Superfund) since November 4, 2009, marking it as one of the most contaminated sites in the United States requiring priority federal cleanup. | med |
| 05 | Natural resources including land, fish, wildlife, surface water, and groundwater in and around Raritan Bay have been injured, destroyed, or lost as a direct result of these companies’ disposal decisions. | high |
| 01 | NL Industries operated its Perth Amboy lead smelter and arranged toxic waste disposal for nearly five decades before regulators took meaningful action. The federal lawsuit was not filed until September 2024. | high |
| 02 | Old Bridge Township purchased the contaminated seawall property in 1983 with knowledge of lead waste deposits. The municipality is now listed as a defendant alongside the corporations responsible for the contamination. | high |
| 03 | EPA did not send NL Industries a formal liability notice until February 2012, and did not file suit until September 2024. In the intervening years, the federal government spent over $32 million in taxpayer money on cleanup. | high |
| 04 | Multiple successor corporations are named as defendants because the original polluting companies were acquired, restructured, or renamed. This corporate complexity delayed accountability for decades. | med |
| 05 | The remedial investigation did not begin until September 2010, more than 35 years after NL’s smelting operations ended. The Seawall Sector cleanup design was not even initiated until May 2017. | med |
| 01 | As of May 31, 2023, the United States government had incurred $32,268,119 in unreimbursed cleanup costs at this site. Not one dollar of this cost was borne by the companies that created the problem before the lawsuit. | high |
| 02 | EPA expects to incur additional future response costs at the site. The Seawall Sector cleanup has not been completed as of the filing date, meaning taxpayers will continue to fund the cleanup. | high |
| 03 | New Jersey state agencies have also incurred independent cleanup and natural resource damage assessment costs that are being claimed against defendants under the New Jersey Spill Act. | med |
| 04 | The destruction of natural resources in Raritan Bay represents a loss of ecological services, including fisheries and coastal habitat, that benefits the public. These losses have not been fully quantified. | med |
| 01 | The lawsuit names 21 corporate defendants plus Old Bridge Township. The involvement of so many companies, many operating through successor entities, illustrates how corporate restructuring shields polluters from accountability. | high |
| 02 | NL Industries received EPA’s first demand for cost reimbursement in February 2012. The company apparently refused to pay, requiring a federal lawsuit filed more than 12 years later to force accountability. | high |
| 03 | Several named defendants are successors in interest to the original polluting companies, including Rio Tinto entities (successor to Capper Pass and Son), Clarios (successor to Globe-Union), and EnerSys (successor to Electric Storage Battery Co.). Each corporate transaction created another layer of distance from liability. | med |
| 04 | The complaint seeks joint and several liability under CERCLA, meaning each defendant can be held responsible for the full cost of cleanup regardless of their individual contribution to the contamination. This is the only tool available to address decades of shared corporate misconduct. | med |
Timeline of Events
Direct Quotes from the Legal Record
“[The agencies] concluded that, due to the elevated lead levels, a public health hazard exists at the Seawall in Laurence Harbor, the beach adjacent to and west of the Seawall, and the Western Jetty at the Cheesequake Creek Inlet, including the waterfront area immediately west of the inlet.”
💡 This is the official government finding that the community’s beach was too dangerous to use. It took decades of contamination and active investigation to reach this conclusion.
“The ROD indicated that there were approximately 11,000 cubic yards of slag and other source material at the Site, and 80,000 cubic yards of additional contaminated soils and sediments that contain lead above cleanup levels.”
💡 The sheer volume of toxic material documents that this was not incidental pollution but decades of systematic dumping.
“At the time of its purchase in 1983, Old Bridge had knowledge that lead waste had been deposited at the property on which the Seawall was located.”
💡 Old Bridge Township is not an innocent victim here. The municipality purchased contaminated land with eyes open and allowed the situation to fester for decades.
“The presence of slag and battery casings have produced adverse ecological effects to natural resources such as aquatic, terrestrial and avian species. The continued presence of contaminated soil, sediment, and surface water pose further risk to natural resources and their services.”
💡 Fish, birds, and aquatic life have been harmed. The damage is ongoing. This was not a one-time spill but a perpetual source of poisoning.
“NL hired Liberty Trucking Co. (‘Liberty Trucking’) of Fords, New Jersey, to dispose of waste from NL’s Perth Amboy lead smelting operations, including furnace slag and battery casings.”
💡 NL did not accidentally pollute. It made a deliberate corporate decision to hire a company to take away its toxic waste. Where that waste went was the predictable result of that decision.
“NJDEP brings this action and has standing to sue to protect the sovereign and quasi-sovereign interests of the State, including public resources and the environment, in its parens patriae authority as sovereign and protector of its citizens and territory.”
💡 New Jersey is suing on behalf of its people. The communities who swam, fished, and sunbathed on this shoreline are the ones whose interests are being represented in court.
“As of May 31, 2023, the United States had incurred approximately $32,268,119 in unreimbursed response costs at the Site. EPA expects to incur future response costs at the Site as well.”
💡 Taxpayers have already paid over $32 million for a mess created by private corporations prioritizing cheap disposal over public safety. That bill will keep growing.
