 Web-Based Well Water Interpretation Tool

The Residential Water and Sewage Program at ODH has worked with OSU Extension and the Ohio Environmental Protection Agency on the development of a new Web-based water quality interpretation tool for private well owners. The purpose of the tool is to help private well owners who have their water sampled from their well to understand the lab results and what actions they should take if necessary. Water sample results from a lab sheet are entered into the tool and with one click, well owners are provided with the standard for the parameter of interest, the natural range in ground water in Ohio for comparison, recommendations on actions, health effects and treatment options if applicable.

The tool is part of this website hosted at OSU Extension and developed by Extension and state of Ohio agencies to provide information to well owners:
