Understanding and spotting possible pollution sources is important. It's the first step to safeguard drinking water for you and your family.

Some threats come from nature. Naturally occurring contaminants such as minerals can present a health risk. Other potential sources come from past or present human activity - things that we do, make, and use such as mining, farming and using chemicals. Some of these activities may result in the pollution of the water we drink.

Several sources of pollution are easy to spot by sight, taste, or smell. (See Quick Reference List.), however many serious problems can only be found by testing your water. Knowing the possible threats in your area will help you decide on the kind of tests you need.
