Private water
What you need to know to keep your private water safe
Private water systems can expose people to a variety of contaminants that can cause poor health outcomes. While not mandated or regulated, private water owners can follow the same guidelines to protect their water source and eliminate health risks from contaminated water used in public water systems.
Water contaminants are grouped into six categories: microorganisms such as E. coli and Giardia; organic chemicals such as PFAS (poly- and perfluoroalkyl substances); radionuclides such as radon; inorganic chemicals such as lead; and disinfectants and disinfectant byproducts. When not properly managed, wastewater can also contaminate your private water supply.
Proper maintenance is essential to keep your water safe to drink.
