Advisories and Violations

Public Drinking Water Use Advisories

Ohio EPA will no longer host and update the advisory tracker. Ohio EPA is committed to transparency and open communication regarding all public records for public water systems (PWSs). To find out more about a PWS's maximum contaminant level (MCL) violations, enforcement actions associated with the MCL violations, and public notices (PNs), please see the eDocument system (eDoc). A short eDoc Training Video shows how to efficiently search eDoc.

To promote transparency, Ohio EPA also has developed a way to access publicly available drinking water data from the agency through the Drinking Water Viewer application. A user guide for the Drinking Water Viewer has also been created.

For community water systems (e.g., cities, villages, mobile home parks, nursing homes), information about source water, vulnerabilities, contaminants detected in water, violations of federal rule(s), and other important drinking water information, can be found in the annual Consumer Confidence Report. This report can be obtained using eDoc or by contacting the PWS. 

Access to drinking water information for public water systems across the state are available at the Data Reporting - Data Received page. You can download sample results and Monthly Operating Reports (MORs) in an Excel format. 

Apparent Monitoring Violations

Ohio’s public water systems are required to monitor for a variety of contaminants on a regular basis, according to the system's monitoring schedule. When a public water system fails to monitor as required, Ohio EPA issues them a monitoring violation. Before issuing a violation to the system, Ohio EPA publishes a list of apparent monitoring violations, to give the system or the laboratory a final opportunity to submit sample results.

To view the list of systems that are on the current apparent violation list for missed monitoring, please click on the link below. This list contains the systems that do not have results submitted to Ohio EPA for the specified monitoring time period. Laboratories that have any of the missing results should submit the results to this office electronically as soon as possible in order to remove a system from the apparent violation list and prevent the system from receiving a violation letter. If you have any questions about this information, please contact the staff member indicated or call 614.644.2752.

Current Apparent Monitoring Violations for Chemical Contaminants

Ensure confidence in the quality of your water and save money by sampling on time. It costs an average of $25 for each total coliform sample and $20 for each nitrate sample. Failing to sample for total coliform or nitrate will cost you $150 or more in penalties for each monitoring violation. Save a Dime.
