Telephone numbers for most local water providers are available on the Where You Live: Your Drinking Water Quality Reports Online Web site, available at http://cfpub.epa.gov/safewater/ccr. You can browse by choosing your state and then locating the water company on resulting state page by scrolling down or select Next or View All to see additional pages. Alternatively, you may also search directly by entering your city, town, county, ZIP code, or water system name. If you are not able to locate the phone number from EPA's Web site, you should check for the number on your water utility bill or look in your local phone book.
In addition, you can go to http://www.epa.gov/home/health-and-environmental-agencies-us-states-and-territories#CT for contact information by clicking on your State.
