Water quality can vary greatly from city to city but the majority of U.S. cities have some sort of pollution in their drinking water. City water must be filtered by the city to take out contaminants such as motor oil, sewage, acid from rainwater, as well as more dangerous toxins like bromate, total trihalomethanes, chlorine, antimony, cadmium, copper, fluoride, atrazine, chlordane, picloram, styrene, alpha particles and uranium. However, even after the city filters out these harmful contaminants some may continue to exist in low levels.

Water quality in the United States has a great deal of variation. The Environmental Protection Agency (EPA) establishes and enforces water quality standards for the entire nation. However the EPA does not test the water in every state and city. The EPA holds the individual states responsible for water quality testing. States must keep detailed records, which the EPA uses to ensure compliance with federal law. Private water suppliers must follow the same procedures.
