Additional Resources
If you are a private well owner, you are responsible for the quality of your drinking water and maintaining your well system. Regular water testing and well inspection are imperative in order to keep your water well operating properly and to ensure there are no contaminants so you always have a safe supply of drinking water. At a minimum, your well water should be tested every year for bacteria, the most common water quality problem. Other tests may be required or recommended, depending on where you live and what is located near your water well system.
For additional water well testing recommendations, if you have any questions on water well testing, or if you have any questions once you receive your water well test results, contact the wellcare® Hotline by calling 888-395-1033, send us an email at info@wellcarehotline.org, or chat with us live, or contact your local Health Department or Cooperative Extension Office.
