What to Do After Reading Your Utility's Water Records
After reviewing a utility's records on Water Utility Report, the most useful next step is to check which record types are present, verify the official source, and decide whether household-specific testing makes sense.
What this page helps with
- Understanding the order in which to review official records
- Knowing what to verify directly with your utility
- Deciding whether a third-party water test is relevant
- Saving your utility to get future record updates
- Understanding what these records do and do not tell you
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
- Violation history reported to EPA through the Safe Drinking Water Information System (SDWIS)
- PFAS and other contaminant sampling records from UCMR 5 and other monitoring programs
- Consumer Confidence Report links where available in EPA-tracked databases
- Public water system identification numbers (PWSID) and service area information
What official records may not show
- Federal records may lag weeks to months behind current local conditions
- Local utility notices, boil-water advisories, and press releases are not part of federal SDWIS records
- Missing or incomplete records do not confirm a contaminant is absent
- Utility-level records reflect sampling at official monitoring points, not at every household tap
- Private wells are not covered by public utility records
Recommended order of review
- 1Confirm the utility name and PWSID match your actual water provider.
- 2Check source links — verify whether a Consumer Confidence Report or official data source is linked.
- 3Review PFAS and UCMR 5 sampling records if present. Note that detections are not automatically violations.
- 4Review the violation history. Note whether violations are health-based or monitoring/reporting in nature.
- 5Read the 'What this does not mean' section on any record type you are unsure about.
- 6Check your utility's own website or Consumer Confidence Report for context on treatment and compliance plans.
- 7Consider independent testing if your concern is household-specific — for example, if you have an older home with lead plumbing.
- 8Save this utility to receive notifications when official records change.
How to confirm you have the right utility
Water Utility Report pages are organized by PWSID — the public water system identifier assigned by EPA. If you are unsure which utility serves your address, use the address or ZIP search. Some addresses are served by a sub-utility or a reseller that has its own PWSID, so the utility name on your bill and the PWSID in federal records may differ slightly.
When records look confusing or incomplete
Official federal records are updated on reporting cycles that can vary from monthly to annually. A gap in records is not evidence of a problem — it may reflect a reporting lag, a system that is not required to monitor for a specific contaminant, or data that has not yet been synced to the federal database. For the most current picture, contact your utility directly or check your state drinking water agency's records.

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
How do I know which water utility serves my address?
Use the address or ZIP search on Water Utility Report. If you are unsure, your water bill should include the utility name and often the PWSID. Your state drinking water agency also maintains a directory of public water systems by service area.
What is a PWSID?
A PWSID (Public Water System Identifier) is a unique code assigned by EPA to every public water system in the United States. It is the primary identifier used in federal databases including SDWIS. Water Utility Report pages are organized by PWSID.
Should I test my water even if the utility has no violations?
Utility-level records reflect compliance monitoring at official sampling points. They do not describe conditions at every tap in the service area. If you have an older home with lead plumbing or a service line of unknown material, household testing can provide information that utility records cannot. Contact a state-certified laboratory for guidance.
How often are Water Utility Report records updated?
Water Utility Report syncs with federal databases including EPA SDWIS and UCMR 5. Update frequency varies by record type — violation records are updated as utilities report to EPA, which occurs on state-specific schedules. PFAS sampling records from UCMR 5 are updated as EPA publishes new data.
What does 'no records found' mean?
It means no records of that type appeared in the federal datasets Water Utility Report aggregates for this system. It does not mean the contaminant is absent. The system may not have been required to monitor, the data may not yet be in federal databases, or local records may differ. Check with your utility or state agency.
Where can I find my utility's Consumer Confidence Report?
Water Utility Report displays CCR links where they appear in EPA-tracked databases. If no link is shown, check your utility's website directly. Many utilities post their CCR as a PDF on their official site. See the help article on missing CCRs for more steps.
