Over 43 million people nationwide depend on private wells for drinking water. Kansas follows that trend, with more than 151,000 people sourcing drinking water from domestic private wells, according to the Kansas Geological Survey. Most citizens tout their well water as fresher and cleaner than chemically treated water from municipal water systems.

However, thinking your well water tastes better is very different than knowing your water is safe for consumption, according to Stacie Minson, an extension watershed specialist with the Kansas Center for Agricultural Resources and the Environment (KCARE) at Kansas State University.
