Topsoil runoff from farm, central Iowa (2011). Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and manufacturing industries—although laws and regulations introduced in the late 20th century have improved water quality in many water bodies.

The National Environmental Education Act of 1990 is an act of the United States Congress to promote environmental education. [1]In this act, Congress found that "threats to human health and environmental quality are increasingly complex, involving a wide range of conventional and toxic pollutants in the air and water and on the land" and that "there is growing evidence of international ...
[229] [230] The new regulations benefit energy companies by making it more difficult for states to block projects such as oil pipelines by using the Clean Water Act. Currently under Section 401 of the Clean Water Act, states can reject any project if they believe it could impact the state's water.
The water gap is an enduring legacy of manifest destiny; the infrastructure, and legislation, that came with it still largely define how water is used. In the American West, irrigated agriculture ...
The Clean Water Act has made great strides in reducing point source water pollution, but this effect is overshadowed by the fact that nonpoint source pollution, which is not subject to regulation under the Act, has correspondingly increased. [41] One of the solutions to address this imbalance is point/nonpoint source trading of pollutants.
Water scarcity poses a threat to ecosystems and biodiversity, primarily through its impact on aquatic habitats, rivers, wetlands, and lakes. [3] Decreased water flows and the drying of water bodies disrupt the delicate balance of ecosystems, affecting a range of species including fish, amphibians, and water-dependent plants, experience habitat loss and fragmentation, affecting their ...
Despite improvements in water quality regulations, disparities in access to clean drinking water persist in marginalized communities. A 2017 study by the Natural Resources Defense Council (NRDC) highlighted that rural areas and low-income neighborhoods are disproportionately affected by water contamination, often due to aging infrastructure and ...
Levels of air and water pollutants that are measured and controlled have dropped substantially in recent decades, far more than CO2 emissions. However, this improvement should be interpreted with caution for several reasons. For one, while U.S. industries create thousands of chemicals, the Safe Drinking Water Act only covers around 95 of them.
