The Safe Drinking Water Act is the principal federal law governing public water systems. [1] These systems provide drinking water through pipes or other constructed conveyances to at least 15 service connections, or serve an average of at least 25 people for at least 60 days a year. As of 2017 there are over 151,000 public water systems. [2]
The drinking water contaminants that can have chronic effects include chemicals (such as disinfection byproducts, solvents and pesticides), radionuclides (such as radium), and minerals (such as arsenic). Examples of these chronic effects include cancer, liver or kidney problems, or reproductive difficulties. [35]
Provides drinking water for 17 million people, including half of New York City via the Delaware Aqueduct. [142] The longest free-flowing (undammed) river in the Eastern United States. [143] Named the 5th most polluted river in the United States by eco-activism groups, primarily in the Philadelphia/Chester region. [144] [145]
A group of international researchers has discovered a previously unknown chemical compound in U.S. drinking water — and it could be toxic.. The compound — known as chloronitramide anion — is ...
About 40% of drinking water in America comes from groundwater sources. [15] When contaminants enter aquifers, the pollution spreads, eliminating the potential to use the aquifer for drinking water. Groundwater contamination is often the result of chemicals that seep through the soil and into the water supply, such as pesticides and fertilizers ...
Water pollution (or aquatic pollution) is the contamination of water bodies, with a negative impact on their uses. [1]: 6 It is usually a result of human activities. Water bodies include lakes, rivers, oceans, aquifers, reservoirs and groundwater. Water pollution results when contaminants mix with these water bodies. Contaminants can come from ...
The burden of polluted drinking water disproportionally effects under-represented and vulnerable populations. [11] Communities that lack these clean drinking-water services are at risk of contracting water-borne and pollution-related illnesses like Cholera, diarrhea, dysentery, hepatitis A, typhoid, and polio.
