Private Well Water Testing Program


Access to a quality water source is vital to human development and maintaining a healthy lifestyle. Some water quality issues are easy to detect, while others are colorless, orderless and detectable only by lab analysis. To be sure your water is safe, it should be sampled and tested for contaminants periodically. Newly constructed wells are tested for bacteria and 17 inorganic parameters as a part of the well permit. Franklin County Environmental Health Services offers well water sampling and testing for existing wells to the citizens in the county. If you are experiencing water quality issues with your well water, or have safe drinking water concerns, contact Environmental Health Services to speak with a specialist.

Please refer to the department fee schedule for the cost associated with each sample.

Bacteria can be introduced into a water system anytime repairs, maintanence, or damage occurs. If a sample indicates the presence of bacteria in a water system, chlorination is recommended.
