Americans aged 21 and older, on average, drink 1,043 mL (36.7 imp fl oz; 35.3 US fl oz) of drinking water a day, and 95% drink less than 2,958 mL (104.1 imp fl oz; 100.0 US fl oz) [of what?] per day. Exercise and heat exposure cause loss of water and therefore may induce thirst and greater water intake. [6]
The most common standards used to monitor and assess water quality convey the health of ecosystems, safety of human contact, extent of water pollution and condition of drinking water. Water quality has a significant impact on water supply and oftentimes determines supply options.
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.
People can experience acute health effects from almost any contaminant if they are exposed to extraordinarily high levels (as in the case of a spill). In drinking water, microbes, such as bacteria and viruses, are the contaminants with the greatest chance of reaching levels high enough to cause acute health effects.

Long-term effects of alcohol include changes in the metabolism of the liver and brain, several types of cancer and alcohol use disorder. [1] Alcohol intoxication affects the brain, causing slurred ...
The environmental impact of reservoirs comes under ever-increasing scrutiny as the global demand for water and energy increases and the number and size of reservoirs increases. Dams and reservoirs can be used to supply drinking water , generate hydroelectric power , increase the water supply for irrigation , provide recreational opportunities ...
Most water is purified and disinfected for human consumption ( drinking water ), but water purification may also be carried out for a variety of other purposes, including medical, pharmacological, chemical, and industrial applications. The history of water purification includes a wide variety of methods.
