Eight percent of the community water systems—large municipal water systems—provide water to 82 percent of the US population. [2] The Safe Drinking Water Act requires the US EPA to set standards for drinking water quality in public water systems (entities that provide water for human consumption to at least 25 people for at least 60 days a ...
[82] [83] The United States Geological Survey reported that at least 45% of drinking water in the United States contains per- and polyfluoroalkyl substances (PFAS), commonly referred to as "forever chemicals." [84] [85] Many solutions to water pollution in the United States can be implemented to curtail water pollution.
Climate change has led to the United States warming by 2.6 °F (1.4 °C) since 1970. [18] The climate of the United States is shifting in ways that are widespread and varied between regions. [19] [20] From 2010 to 2019, the United States experienced its hottest decade on record. [21]
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 industry, although laws and regulations introduced in the late 20th century have improved water quality in many water bodies.

It depends on activity, age, health, and environment. In the United States, the Adequate Intake for total water, based on median intakes, is 4.0 litres (141 imp fl oz; 135 US fl oz) per day for males older than 18, and 3.0 litres (106 imp fl oz; 101 US fl oz) per day for females over 18; it assumes about 80% from drink and 20% from food.

Water cycle showing human influences and major pools (storages) and fluxes. [19] The water cycle describes the processes that drive the movement of water throughout the hydrosphere. However, much more water is "in storage" (or in "pools") for long periods of time than is actually moving through the cycle.
In the United States, a nationwide compilation of these metered quantities by the United States Geological Survey (USGS) shows average domestic water deliveries (for both indoor and outdoor purposes) by public water suppliers to single-family and multifamily dwellings were about 89 gallons (337 liters) per person per day in 2010 [4] and 83 ...
