The Virginia Well Owner Network and Household Water Quality Program
Private Water Supplies in Virginia • About 1.7 million Virginians rely on wells, springs or cisterns for their household water (USGS, 2010) • In the US, municipal water supplies are regulated by the EPA under the Safe Drinking Water Act, which mandates routine testing and appropriate treatment. • Homeowners relying on private water supplies: • Are responsible for all aspects of water system management • Often lack knowledge and resources to effectively manage • Usually don’t worry about maintenance until problems arise
Overview of private water supplies • Wells • Drilled or bored • Range from 20-1000+’ feet deep • Locate at least ~100’ from sources of contamination • Casing, grouting, sanitary well cap protect well from surface water contamination Well cap Casing Grout Photo credit: A Guide to Private Water Systems in Pennsylvania: A manual for Rural Homeowners on the Proper Construction and Maintenance of Private Wells, Springs and Cisterns; Rorrer Well Drilling, Inc.
Overview of private water supplies • Springs • Formed when side of a hill, valley bottom, or other excavation intersects groundwater • Highly susceptible to contamination • Cisterns • Collection and storage of rainwater, often from rooftop Photo credit: http://aquariuspump.com/springbox.aspx
