What a violation is. Violations are issued for a public water system when there is a failure to meet certain state/region or federal drinking water regulations.

  • Monitoring — A MON violation is a violation of a monitoring requirement or a reporting requirement associated with the monitoring. A monitoring violation occurs when a public water system owner does not collect a required sample. A reporting violation occurs when a public water system owner does not report the result(s) to the state from a sample that was collected. When a public water system's owner does not collect a required sample, the violation is often referred to as a monitoring and reporting violation.
  • Reporting — A RPT violation occurs when public water system owners fail to report certain information. The RPT category does not include the failure to report analytical results, which falls under the MON category.
  • Public Notice — A PN violation occurs when a public water system owner does not notify the public about another violation in a timely or appropriate fashion.
  • Maximum Contaminant Level — An MCL violation means a contaminant has been detected above maximum contaminant level consistently in drinking water. MCL is the highest level of contamination that the U.S. Environmental Protection Agency (EPA) allows in drinking water. MCLs ensure that drinking water does not pose a short-term or long-term health risk.
  • Treatment Technique — A TT violation occurs when a public water system owner fails to apply a prescribed treatment technique by the allotted time. Actions that are classified as treatment techniques are broad. Examples of TT violations include: failure to employ a certified operator, inadequate removal of organic materials from raw water.
