The Raritan River is the twelfth most polluted river in the US
The Raritan River, the longest river solely within New Jersey, is the twelfth most polluted river in the US. It flows through 49 municipalities, including an industrial corridor known as Central New Jersey's "Chemical Belt". The river also passes through many of New Jersey's 18,500 contaminated industrial sites, with over 200 contaminated sites adjacent to or draining into the lower Raritan River. These include abandoned industrial sites, Superfund sites, old landfills, dredge dumping grounds, and old army arsenals.
The American Cyanamid Company, which produced fertilisers, cyanide, and other chemical products, is one of the major contributors to the river's pollution. For decades, the company released chemical waste directly into the river, causing significant harm to the natural resources in the sediments and surface waters of the Raritan River and its tributaries. Other sources of pollution include sewage treatment plants, which contribute to "nutrient" pollution such as nitrogen and phosphorus, and non-point source pollution from land runoff, precipitation, and atmospheric deposition.
The Raritan River Project, founded by the Edison Wetlands Association (EWA) in 1995, aims to protect human health, quality of life, and the environment from threats such as pollution, overdevelopment, and lack of public access to waterways. The project focuses on identifying and reducing sources of contamination, stopping ongoing pollution, cleaning up existing contamination, and restoring the watershed. Restoration efforts for the river include the removal of the Weston Mill Dam, which will help restore passage for migratory fish and improve water quality and habitat.
Despite these efforts, the Raritan River continues to face challenges. Residents remain exposed to toxic waste through recreational use of the river and consumption of contaminated fish, despite warnings about potential health hazards. The river's water quality has received a grade of C-, indicating that there is much room for improvement. While some parameters, such as temperature, oxygen, and pH levels, receive high grades, others, such as stream habitat, nutrients, and other pollutants, receive failing grades. Protecting the river and improving its water quality require a collective effort from government entities, commercial organisations, and individuals.

The river flows through New Jersey's Chemical Belt, with over 200 contaminated sites
The Raritan River is the longest river solely within New Jersey, flowing through 49 municipalities. One of these areas is an industrial corridor known as Central New Jersey's "Chemical Belt". The river flows through or adjacent to over 200 contaminated sites, including abandoned industrial sites, Superfund sites, old landfills, dredge dumping areas, and old army arsenals.
The river's contamination is largely due to industrial waste, with factories dumping toxic chemicals, dyes, and waste into the water for decades without regulation. The American Cyanamid Company, for example, produced fertilizers, cyanide, and other chemical products, releasing their waste directly into the river. Other sources of pollution include irresponsible management of hazardous materials, fertilizers, pesticides, failing septic systems, and non-point source pollution, which comes from everyday community members.
The Raritan River Project, founded by the Edison Wetlands Association (EWA) in 1995, aims to protect human health, quality of life, and the environment from these threats. Despite warnings, residents continue to be exposed to toxic waste through recreational use of the river and by eating contaminated fish.
Restoration efforts are underway, with a focus on removing the Weston Mill Dam to improve water quality and habitat, as well as cleaning up Superfund sites. The watershed received a C- grade, indicating that there is much room for improvement in terms of stream habitat, nutrients, and other pollutants. The goal is to strive for an A or B grade to ensure clean and safe water for the 1.8 million people in New Jersey who rely on the Raritan River for drinking water.

The American Cyanamid Company released chemical waste into the river for decades
The Raritan River is the longest river solely within New Jersey, flowing through 49 municipalities. It is also the twelfth most polluted river in the US. The river flows through many of New Jersey's 18,500 contaminated industrial sites. Over 200 contaminated sites are adjacent to or drain into the lower Raritan River, including abandoned industrial sites, Superfund sites, old landfills, and old army arsenals.
The American Cyanamid Company, which began operations in the early 1900s, is one of the major contributors to the pollution of the Raritan River. The company started by developing an effective fertilizer ingredient, a compound of nitrogen, lime, and carbide called cyanamid. By the early 1920s, the company expanded its product line to include cyanide for gold and silver extraction and hydrocyanic acid for rubber production. Over the next few decades, the company added chemicals, plastics, dyes, and resins to their line of products. They also provided valuable medical products during World War II.
However, the diversification of their product line also led to an increase in chemical waste. Starting in the 1920s, the company began releasing chemical waste directly into the Raritan River. This practice continued for decades, with waste being buried on-site or stored in unlined "impoundments" or reservoirs. By the time waste treatment began in 1940, it is estimated that 800,000 tons of chemical wastes had already been discharged into the river.
The pollution caused by the American Cyanamid Company and other industrial sites has had significant negative impacts on the Raritan River and its ecosystems. The river has been contaminated with volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), polychlorinated biphenyls (PCBs), pesticides, and metals. These chemicals pose serious health hazards to humans, wildlife, and fish populations.
Efforts are now being made to remediate the contaminated sites and restore the watershed. The Environmental Protection Agency (EPA) designated the area as a Superfund site in 1983, and direct discharge into the river ended in 1985. The final restoration plan and environmental assessment for the site were released in 2016, and it included the removal of the Weston Mill Dam to restore the natural flow of the river and improve water quality. The cleanup and restoration projects are expected to play a crucial role in restoring the health of the Raritan River and mitigating the impacts of pollution.

The river's water quality has deteriorated over time, with higher concentrations of most constituents
The Raritan River is the longest river solely within New Jersey, flowing through 49 municipalities. The river has long been polluted by industrial waste, with chemical manufacturing, coal tar distillation, and other manufacturing practices causing issues for the river's health. The American Cyanamid Company, for example, released chemical waste directly into the river for decades.
The river's water quality has indeed deteriorated over time, with higher concentrations of most constituents below Manville than those observed upstream. This is due to detrimental human activities, with the river flowing through an urban and industrial complex. Data collected between the late 1920s and early 1970s shows a general deterioration in water quality with time in the river below Manville, with dissolved-oxygen and biochemical-oxygen-demand data indicating a decline.
Comparing data from different periods, it is evident that the maximum concentration of dissolved solids observed during the study period increased from 464 to 1,520 mg/L, while orthophosphate levels rose from 0.93 to 2.3. These increases in pollutant concentrations are indicative of the river's deteriorating health.
The Raritan River Project, founded by the Edison Wetlands Association (EWA) in 1995, aims to protect human health, quality of life, and the environment from threats such as pollution. The project recognizes the river's pollution issues and works towards identifying and reducing contamination sources. Restoration efforts are also underway, with a focus on removing the Weston Mill Dam to improve water quality and habitat for migratory fish.
The river's health is crucial as it serves as the source of drinking water for 1.8 million people in New Jersey. While some parameters, such as temperature, oxygen, and pH levels, receive high grades, others, such as stream habitat, nutrients, and pollutants, require significant improvement.

Efforts are being made to restore the river and its watershed, including removing the Weston Mill Dam
The Raritan River in New Jersey has been long polluted by industrial waste. Over 200 contaminated sites, including abandoned industrial sites, Superfund sites, old landfills, and old army arsenals, are adjacent to or drain into the river. The Edison Wetlands Association (EWA) founded the Raritan River Project in 1995 to protect human health, quality of life, and the environment from these threats. The mission of the Raritan River Project is to clean up and protect the lower reaches of the Raritan River by identifying and reducing sources of contamination.
Efforts are being made to restore the river and its watershed. The Watershed Organization has been a partner in the Raritan Basin Fish Passage Initiative, and since 2011, three dams have been removed from the Raritan River, restoring over a dozen miles of migratory fish habitat. The removal of these dams has also helped to prevent flooding and improve water quality. The Weston Mill Dam, located about 1.5 miles upstream of the confluence of the Millstone and Raritan Rivers, is one of the dams that has been removed as part of this initiative. The original dam, which was built around 1700 to power a mill, blocked migratory fish such as American shad, striped bass, and herring from swimming upriver to reproduce. The concrete replacement constructed in the 1930s was obsolete and dangerous for recreational users of the river. By removing the dam, the river can return to its natural free-flowing state, improving water quality and reducing pollution. The project was funded by the National Oceanic and Atmospheric Administration, the U.S. Department of the Interior, and the New Jersey Department of Environmental Protection, with implementation by Wyeth Holdings LLC.
Another effort to restore the river includes the cleanup of the American Cyanamid Superfund Site, a 575-acre site located along the Raritan River. For many years, the American Cyanamid Company used the site for chemical manufacturing and coal tar distillation, releasing harmful chemical wastes into the river and its tributaries. A final restoration plan and environmental assessment have been released, and the site's cleanup will be an important part of restoring the Raritan River.
In addition to these site-specific efforts, there is a broader focus on protecting the watershed through responsible management of hazardous materials, fertilizers, pesticides, and septic systems. The Raritan Headwaters organization has identified key areas of improvement, including protecting forests and riparian buffers, controlling stormwater, implementing best management practices on farms, and increasing community resilience. These collective efforts aim to restore the health of the Raritan River and ensure safe and sustainable water resources for the people and ecosystems that depend on it.
