The Virginia Household Water Quality Program provides practical information to homeowners about maintaining and protecting private water systems such as wells, spring and cisterns. In the U.S. regular testing and treatment of public water supplies is required, but private water system owners must take care of this themselves. Drinking water clinics are offered through local Extension offices in 50-60 counties per year, providing affordable water testing, interpretation of test results and information about maintenance of private water systems and dealing with water problems.  To find a clinic near you, click HERE.
