Do You Know Where Your Drinking Water Comes From?

Clean drinking water is one of the world's most precious resources. In the United States, clean drinking water is something that we don't think about enough. Usually, it's free of contaminants and isn't a source of illness. However, drinking water-related outbreaks do occur. In fact, their numbers are increasing, as CDC data for the latest reporting periods of 1999-2000 show*. In parts of the developing world, clean water has never been easy to come by. As a result, millions of people become ill every year and millions more die from parasites, bacteria, viruses, and other contaminants found in drinking water.

Take a moment to consider the following questions about drinking water:

1 Are you one of the 52% of Americans who depend on ground water for your drinking water, either from a public source or private well?

If you receive your drinking water from a private well, we suggest that every year you schedule a well checkup. Why is this important? Over half of the disease outbreaks linked to drinking water reported to CDC in 1999-2000 were ground water-related. Most occurred because the wells were either improperly built or maintained.

2 Does your water come from a public source such as ground water
(a well) or surface water (a river)?

If so, contact your water utility. Ask for a copy of their Consumer Confidence Report (CCR), sometimes also called a Water Quality Report. Water providers now must produce this report every year. It tells you what substances have been found in the water and whether or not it's safe to drink. Your cities Water Quality Report may be posted on the Environmental Protection Agency's website. See the EPA Consumer Confidents Reports page for details.
