As with many countries, pollution in the United States is a concern for environmental organizations, government agencies and individuals.

The Act to Prevent Pollution from Ships is a United States law that implements the provisions of MARPOL and the annexes to which the United States is a party. The most recent U.S. action concerning MARPOL occurred in April 2006, when the U.S. Senate approved Annex VI, which regulates air pollution. Following that approval, in March 2007, the House of Representatives approved legislation to implement the standards in Annex VI, through regulations to be promulgated by Environmental Protection Agency in consultation with the U.S. Coast Guard.

Air quality laws govern the emission of air pollutants into the atmosphere. A specialized subset of air quality laws regulate the quality of air inside buildings. Air quality laws are often designed specifically to protect human health by limiting or eliminating airborne pollutant concentrations. Other initiatives are designed to address broader ecological problems, such as limitations on chemicals that affect the ozone layer, and emissions trading programs to address acid rain or climate change. Regulatory efforts include identifying and categorizing air pollutants, setting limits on acceptable emissions levels, and dictating necessary or appropriate mitigation technologies.

The Calumet River is a system of heavily industrialized rivers and canals in the region between the neighborhood of South Chicago in Chicago, Illinois, and the city of Gary, Indiana. Historically, the Little Calumet River and the Grand Calumet River were one, the former flowing west from Indiana into Illinois, then turning back east to its mouth at Lake Michigan at Marquette Park in Gary.

The Clean Boating Act of 2008 (CBA) is a United States law that requires recreational vessels to implement best management practices to control pollution discharges. The law exempts these vessels from requirements to obtain a discharge permit under the Clean Water Act.

The Grand Calumet River is a 13.0-mile-long (20.9 km) river that flows primarily into Lake Michigan. Originating in Miller Beach in Gary, it flows through the cities of Gary, East Chicago and Hammond, as well as Calumet City and Burnham on the Illinois side. The majority of the river's flow drains into Lake Michigan via the Indiana Harbor and Ship Canal, sending about 1,500 cubic feet (42 m3) per second of water into the lake. A smaller part of the flow, at the river's western end, enters the Calumet River and ultimately drains into the Illinois and ultimately the Mississippi River.

The Kerr-McGee Corporation, founded in 1929, was an American energy company involved in oil exploration, production of crude oil, natural gas, perchlorate and uranium mining and milling in various countries. On June 23, 2006, Anadarko Petroleum acquired Kerr-McGee in an all-cash transaction totaling $16.5 billion plus $2.6 billion in debt and all operations moved from their base in Oklahoma, United States.
Municipal solid waste (MSW) – more commonly known as trash or garbage – consists of everyday items people use and then throw away, such as product packaging, grass clippings, furniture, clothing, bottles, food scraps and papers. In 2010, Americans generated about 250 million short tons (230 Mt) of trash. In the United States, landfills are regulated by the Environmental Protection Agency (EPA) and the states' environmental agencies. Municipal solid waste landfills (MSWLF) are required to be designed to protect the environment from contaminants that may be present in the solid waste stream.

Lead abatement is an activity to reduce levels of lead, particularly in the home environment, generally to permanently eliminate lead-based paint hazards, in order to reduce or eliminate incidents of lead poisoning.

Love Canal is a neighborhood in Niagara Falls, New York, infamous as the location of a 70-acre landfill that became the site of an enormous environmental disaster in the 1970s. Decades of dumping toxic chemicals harmed the health of hundreds of residents; the area was cleaned up over the course of 21 years in a Superfund operation.

The Medical Waste Tracking Act of 1988 was a United States federal law concerning the illegal dumping of body tissues, blood wastes and other contaminated biological materials. It established heavy penalties for knowingly endangering life through noncompliance. The law expired in 1991.

A polychlorinated biphenyl (PCB) is an organic chlorine compound with the formula C12H10−xClx. Polychlorinated biphenyls were once widely deployed as dielectric and coolant fluids in electrical apparatus, carbonless copy paper and in heat transfer fluids.

Picher is a ghost town and former city in Ottawa County, Oklahoma, United States. This was a major national center of lead and zinc mining at the heart of the Tri-State Mining District.

Pollution in California relates to the degree of pollution in the air, water, and land of the state of California. Pollution is defined as the addition of any substance or any form of energy to the environment at a faster rate than it can be dispersed, diluted, decomposed, recycled, or stored in some harmless form. The combination of three main factors are the cause of notable unhealthy levels of air pollution in California: the activities of over 39 million people, a mountainous terrain that traps pollution, and a warm climate that helps form ozone and other pollutants. Eight of the ten cities in the US with the highest year-round concentration of particulate matter between 2013 and 2015 were in California, and seven out of the ten cities in the US with the worst ozone pollution were also in California. Studies show that pollutants prevalent in California are linked to several health issues, including asthma, lung cancer, birth complications, and premature death. In 2016, Bakersfield, California recorded the highest level of airborne pollutants of any city in the United States.

Pollution in Door County, Wisconsin relates to the degree of pollution in the air, water, and land in Door County, Wisconsin. Pollution is defined as the addition of any substance or any form of energy to the environment at a faster rate than it can be dispersed, diluted, decomposed, recycled, or stored in some harmless form.

The United States federal Superfund law is officially known as the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). The federal Superfund program, administered by the U.S. Environmental Protection Agency (EPA) is designed to investigate and clean up sites contaminated with hazardous substances. Sites managed under this program are referred to as "Superfund" sites. There are 40,000 federal Superfund sites across the country, and approximately 1,600 of those sites have been listed on the National Priorities List (NPL). Sites on the NPL are considered the most highly contaminated and undergo longer-term remedial investigation and remedial action (cleanups).

Toms River: A Story of Science and Salvation is a 2013 non-fiction book by the American author Dan Fagin. It is about the dumping of industrial pollution by chemical companies including Ciba-Geigy, in Toms River, New Jersey, beginning in 1952 through the 1980s, and the epidemiological investigations of a cancer cluster that subsequently emerged there. The book won the 2014 Pulitzer Prize for General Non-Fiction, the 2014 Helen Bernstein Book Award for Excellence in Journalism, and the 2014 National Academies Communication Award.

The Toxics Release Inventory (TRI) is a publicly available database containing information on toxic chemical releases and other waste management activities in the United States.

Wade Dump was a rubber recycling facility and illegal industrial waste storage and disposal facility in Chester, Pennsylvania. It was located at 1 Flower Street on the western bank of the Delaware River just north of the Commodore Barry Bridge. A toxic fire at the site in 1978 burned out of control for several days and resulted in 43 injured firefighters and criminal charges for the owner of the site. The first responders to the fire suffered long term health consequences and higher than normal cancer rates.
