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 the following lists 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 lists for missed monitoring, please click on the links below. These lists contain 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 (preferred method) or by paper as soon as possible in order to remove a system from the apparent violation lists 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.
