River known for its pollution in northeastern New Jersey, United States

Berry's Creek (sometimes referred to as Berrys Creek or Berry Creek) is a tributary of the Hackensack River in the New Jersey Meadowlands in Bergen County, New Jersey. The creek watershed contains a diverse array of wetlands, marshes, and wildlife. The creek runs through a densely populated region and has been subject to extensive industrial pollution during the 19th and 20th centuries. Several companies discharged toxic chemicals into the creek in the 20th century, and these chemicals have remained in the sediment. The creek has the highest concentrations of methyl mercury of any fresh water sediment in the world. Portions of the creek watershed are Superfund sites and cleanup projects began in the late 20th century.

The creek is named for Major John Berry, an early British settler and Deputy Governor of New Jersey. Settlement of New Jersey by European colonists began in the 17th century. Increasing settlements in the early 19th century were accompanied by human alterations to the land in the Hackensack meadowlands, such as clearing forests; building roads, railroads and ditches; and filling wetlands. The Second Industrial Revolution led to construction of heavy manufacturing, storage tanks, and chemical processing plants in the area during the late 19th & early 20th centuries. Upland areas in the Berry's Creek watershed were developed by 1900. In the 1930s municipal sewage discharges began to contribute significant amount of pollutants to the creek and the Hackensack River. (All sewage pipes to the creek were removed by the 1990s.) Urbanization in the region intensified after World War II, with the expansion of roads and highways, including the New Jersey Turnpike (1952), as well as the Meadowlands Sports Complex (1970s). Tide gates were installed in the 1960s to control flooding, and these installations altered the water levels and flows, which consequently altered the ecosystem. The filling of wetlands during the 20th century amounted to a 63% loss of wetlands in the watershed.

The Berry's Creek watershed is , which includes of tidal waterways and marshes and of highly developed upland areas. Within the watershed are many commercial and light industrial sites, portions of the sports complex, several closed landfills, and many roads and highways.

Berry’s Creek was subject to extensive industrial pollution during the 19th and 20th centuries.

F. W. Berk and Company, a chemical processing firm in Wood Ridge and Carlstadt, discharged untreated waste, including mercury, into the creek between 1929 and 1960. In 1960 Berk sold its property to Wood Ridge Chemical Corporation, a subsidiary of Velsicol Chemical Corporation, and the waste discharges continued. In the 1960s the New Jersey Department of Health conducted tests of the plant effluent, although the principal focus at that time was conventional pollutants, for which there were well established analytical testing methods. (Some wastewater samples were analyzed for mercury, however the results were negative due to the insensitivity of the test method employed.) In 1968 the plant was sold to Ventron, which continued operations, although the company also began to study the environmental impacts of its discharges. In 1970 the newly established U. S. Environmental Protection Agency (EPA) also began tests of the plant wastewater, and found there were daily discharges of two to four pounds of mercury into Berry's Creek. Neither the state nor EPA filed formal charges against the plant at that time. Plant operations ended in 1974, when Ventron sold the property to Robert M. Wolf, a real estate developer. In 1976, the New Jersey Department of Environmental Protection (NJDEP; successor to the Dept. of Health) filed a lawsuit against Ventron and other parties for violating the recently enacted New Jersey Water Quality Improvement Act of 1971. The state enacted a new chemical spill law in 1977, the Spill Compensation and Control Act, and additional charges under this law were added to the lawsuit. In 1983 the New Jersey Supreme Court held that Ventron and Velsicol were jointly liable for the environmental damage. The creek has been measured as having the highest concentration of methyl mercury of any fresh water sediment in the world. Between 1 and 2 g of mercury per kg of sediment were detected in samples. A total of discharge of 268 tons of mercury contaminated toxic waste were discharged into the creek between 1943 and 1974. Wolf had demolished the former Ventron plant in 1974, but the residual pollution remained in the creek, rendering the site still unsustainable.

The federal "Superfund" law was enacted by Congress in 1980 to provide for cleanup of hazardous waste sites, and was based on New Jersey’s 1977 spill cleanup law. and the Universal Oil Products site in East Rutherford—as Superfund sites. EPA and NJDEP began detailed assessment and initial cleanup activities on these sites in the 1980s. Contaminated soil was removed and replaced at several properties in 1990, as an interim measure. but completion is projected to continue during the first quarter 21st century.

Through the early 1900s, the predominant plants in the watershed were freshwater species such as cattails and Atlantic white cedar. The plant composition began to change after construction of the Oradell Dam on the Hackensack River in 1921. The dam was built at the head of tide, which increased the salinity of Berry's Creek, and since then the marsh vegetation in has been composed predominately of Phragmites (Phragmites australis). NJDEP has issued advisories warning against harvesting or eating blue crabs from Berry's Creek, the entire Hackensack River watershed and Newark Bay.
