Water supply to rural residences and agricultural operations without rural or public water systems is usually obtained from a private well or surface water supply. In Kansas, more than 73,000 individuals rely on private wells for a water supply. When public and rural water systems that use well water are added to the private well numbers, 34.6% of the Kansas population relies on groundwater for their water supply.
Municipal and rural water systems must maintain water quality standards specified by local, state, or federal requirements; however, owners of private wells are responsible for the water quality of their wells. Permanent contamination of groundwater can decrease property values, affect human and animal health, and involve legal liability.
Testing water from private wells has shown that some wells do not meet the safe drinking water standards used for public water systems. The primary reasons for this reduction in water quality from private wells include:
Following the guidelines for recommended separation distance and direction from potential contamination sources when locating a well can help protect private well water quality. When private wells are appropriately sited and constructed, routine maintenance is required to ensure wells continue to be safe. Wells that do not receive regular maintenance are more likely to produce unsafe water.
Detailed information about properly constructing a well in a safe location and maintenance guidelines for existing wells can be found in two recently updated publications from K-State Research and Extension.
