Water & Health

What's in your water?

Drinking water often comes with contaminants such as micro-organisms, disinfection byproducts, disinfectants, inorganic chemicals and organic chemicals. The Environmental Protection Agency (EPA) tightly regulates municipal water systems and requires them to publish information on the contaminants in the tap water they deliver to their customers. You can check on the quality of your local drinking water at epa.gov/safewater/dwinfo/index.html.
