What a Health-Based Violation Record Means
A health-based violation record in official databases means a utility was officially found to have exceeded a regulatory Maximum Contaminant Level (MCL) or treatment technique requirement during the recorded period.
What this page helps with
- Understanding what a health-based violation record officially indicates
- Knowing the difference between an active and a resolved violation
- Finding official source records for the violation
- Knowing what questions to ask your utility or state agency
- Understanding what Water Utility Report does and does not determine from these records
Important: Water Utility Report summarizes official records and source data. It does not determine whether water is safe to drink. For current safety guidance, check your utility, state drinking water agency, local health department, or a certified laboratory.
What official records can show
- The contaminant and MCL associated with the violation, as officially classified by EPA or the state
- The period during which the violation was recorded
- Whether the violation is listed as resolved or unresolved in federal records
- Public notification records if the utility was required to notify customers
What official records may not show
- The current status of the violation if it was recently resolved but not yet updated in federal records
- What remediation or corrective actions the utility has taken since the violation was recorded
- Whether the violation affected your specific address or service area within the system
- Local state agency actions, enforcement orders, or compliance schedules that may not be in federal databases
What a health-based violation record officially indicates
A health-based violation means EPA or a state drinking water agency officially determined that a measured contaminant level exceeded a regulatory Maximum Contaminant Level (MCL) or a treatment technique requirement. These records are entered into EPA's Safe Drinking Water Information System (SDWIS) following the state's review and enforcement process.
Active vs. resolved violations
Health-based violations can be listed as open (active) or resolved in federal records. A resolved violation means the utility returned to compliance as confirmed by the state agency. However, federal records may lag behind state records — a violation may have been resolved in state systems before the update appears in EPA databases.
What to check officially
- Check the official source record linked from the utility's page for the specific contaminant and MCL involved.
- Search your state drinking water agency's records — they are typically more current than federal records.
- Contact your utility to ask about the current compliance status and any remediation actions underway.
- Check whether a public notification was issued — utilities are required to notify customers of certain violation types.
Water Utility Report displays health-based violation records as officially classified in federal databases. It does not independently verify current compliance status, and it does not determine whether water is safe to drink. Always verify current status with your utility or state drinking water agency.
What to ask your utility
If you see a health-based violation record for your utility, reasonable questions to ask include: Is this violation currently active or resolved? What was the contaminant and level involved? What corrective actions have been taken? Has a public notification been issued? What is the current compliance plan?
What to check next
What this does not mean
- This page does not determine whether water is safe or unsafe to drink.
- A detection record does not automatically mean a violation.
- A missing record does not prove a contaminant is absent.
- Federal datasets may lag behind current local conditions.
- Household plumbing, private wells, and point-of-use conditions may differ from utility-level records.
Frequently Asked Questions
Does a health-based violation mean I should not use my tap water?
Water Utility Report does not make that determination. If you have an active health-based violation and want current guidance, contact your utility, local health department, or state drinking water agency. They can advise on whether any protective measures apply to your situation.
How current are the violation records on Water Utility Report?
Water Utility Report syncs with EPA's SDWIS database, which is updated as states report violations to EPA. There can be a lag between a state-level determination and its appearance in federal records. For the most current status, check your state drinking water agency's records directly.
Can a violation appear in records but already be resolved?
Yes. Violations that have been resolved may still appear in historical records. The violation record will note whether it is open or resolved based on the most recent federal database update. If you believe a record is outdated, you can check with your state agency or use the 'Report a data issue' link on the utility page.
What is a Maximum Contaminant Level (MCL)?
An MCL is an enforceable limit set by EPA under the Safe Drinking Water Act. It is the highest level of a contaminant allowed in public drinking water. MCLs are set based on health effects research and treatment feasibility.
Are all health-based violations the same severity?
No. Health-based violations cover a range of contaminants and MCLs, which have different underlying risk profiles. Not all exceedances represent the same conditions. The specific contaminant, level, duration, and the utility's response are all relevant to context — which is why checking official source records and contacting the utility is important.
What is a public notification requirement?
Under EPA's Public Notification Rule, utilities must notify customers of certain violations, including health-based violations, within specified timeframes. The notification form and timeline depend on the type and severity of the violation.
