The clearest, best tasting water may contain bacteria, nitrates, and nitrites that go undetected until it is too late. A survey coordinated by the Centers for Disease Control and Prevention (CDC) estimates 41% of wells may be contaminated with coliform bacteria. Whether you are on a public or private water supply, the only way to be sure your water is safe is to test it yourself.

Now available is an EPA-based way to check the safety of your water. PurTestTM - Bacteria, Nitrate, Nitrite allows you to easily and accurately test your own water for dangerous contaminants. No laboratories or special equipment required - the tests are quickly and easily performed right at home. A color change from purple to yellow indicates the presence of harmful coliform bacteria. (Contains 1 test)

A "color comparison" test strip for nitrate/nitrites indicates if these are present, and the approximate level. (Contains 2 tests)
