The Kansas Department of Health and Environment discontinued coliform testing of private well samples on August 1, 1989. Assuring the safety of private drinking water supplies really requires an assessment of the well location and construction as well as a site assessment for potential contaminants. For example, a poorly constructed well could be free of contaminants one day and then become highly contaminated the next after a heavy rainstorm washes contaminants into the well. A single sample is not a true indicator of the overall safety or purity of the water.
