Water Quality

The average American consumes 1 to 2 liters of drinking water per day. Virtually all drinking water in the United States comes from fresh surface waters and ground water aquifers. 

Surface waters and aquifers can be contaminated by various chemicals, microbes, and radionuclides. Disinfection of drinking water has dramatically reduced the prevalence of waterborne diseases (such as typhoid, cholera, and hepatitis) in the United States. Other processes may also be used to treat drinking water depending on the characteristics of and contaminants in the source water.

Common sources of drinking water contaminants include:

  • Industry and agriculture
  • Human and animal waste
  • Treatment and distribution
  • Natural sources

If drinking water contains unsafe levels of contaminants, it can cause health effects, such as gastrointestinal illnesses, nervous system or reproductive effects, and chronic diseases such as cancer.
