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.

This excessive use of river water distresses ecosystems and communities, and drives scores of species of fish closer to extinction during times of drought. [50] A 2023 study found that a vegan diet reduced water usage by 54%. [33] A study in 2019 focused on linkages between water usage and animal agricultural practices in China. [51]
Bad management practices include poorly managed animal feeding operations, overgrazing, plowing, fertilizer, and improper, excessive, or badly timed use of pesticides. Pollutants from agriculture greatly affect water quality and can be found in lakes, rivers, wetlands, estuaries, and groundwater.
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 ...
Water pollution may affect either surface water or groundwater. This form of pollution can lead to many problems. One is the degradation of aquatic ecosystems. Another is spreading water-borne diseases when people use polluted water for drinking or irrigation. [3]
Here, more than 1 in 3 Diné, as Navajo people call themselves, must haul water to their homes, often across long distances. The Diné use the least amount of water per person of anyone in the U.S ...
A popular swimming area for families on the banks of the River Thames has been rated as having "poor" water quality. Wallingford Beach in Oxfordshire was made a designated bathing water site in ...
Following findings that the parasite Giardia lamblia, which causes giardiasis, was putatively carried by beavers, the term "beaver fever" was coined by the American press in the 1970s. Further research has shown that many animals and birds carry this parasite, and the major source of water contamination is by humans.
