Water Quality Standards

The EPA has limited the levels of over 90 contaminates that can negatively affect an individual’s health and are either found or likely to be found in water. (http://water.epa.gov/lawsregs/rulesregs/regulatingcontaminants/basicinformation.cfm )

The EPA approved standards for drinking water:

The EPA approved standards for recreational water:

We have different quality standards for recreational and drinking water because it costs more money to meet the standards for water to be considered drinking water as apposed to recreational water, so they have different standards to save money on water that won't be used for drinking.

    What is an example of the difference between a recreational water use standard and a drinking water standard?

      A few examples of the over 90 contaminants that the EPA limits are; Lead, Fluoride, Dalapon, Atrazine, and Endrin.
      A list of these contaminants can be found at http://water.epa.gov/drink/contaminants/index.cfm
