Water quality testing
All large public water utilities, including Clark, are required to do extensive testing of the water provided to customers. We test our water supply for the presence of more than 100 substances each year.
Our goal is to meet your need for a clean, plentiful supply of drinking water at a reasonable cost, while providing long-term management of our precious water resources.
In order to make sure tap water is safe to drink, the EPA regulates the amount of certain substances in public water systems. U.S. Food and Drug Administration regulations establish limits for contaminants in bottled water that must provide similar public health protection.
Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contaminants, but their presence does not necessarily indicate that water poses a health risk. More information about contaminants and potential health effects can be obtained by calling the EPA's Safe Drinking Water Hotline (800-426-4791).
