Since nitrate-N does not smell, taste, or have any color, the only way to know for certain if it is present in your private well is to have it tested by a state-certified water laboratory. Professionals recommend that your water be tested at least annually for nitrate-N and bacteria.
Periodically the Portage County Water Resource Specialist will conduct Nitrate Screening Events throughout the County. These screening events are opportunities for residents to bring in a water sample and have it screened free of charge for nitrates. The screening, while not a certified lab test, will offer residents an idea of what the nitrate-N concentration is in their drinking water.
