About This Data
Common Questions
How do I find my water utility?
Enter your ZIP code in the search box. WaterUtilityReport matches your ZIP to your public water system using EPA service area data, then shows detected contaminants, open violations, and PFAS records for that system.
Where does this water quality data come from?
All data comes from official U.S. government sources: EPA SDWIS for violations and utility records, EPA ECHO for compliance history, and EPA UCMR 5 for PFAS monitoring results. No proprietary scoring or estimates are used.
Can I check PFAS records by city or utility?
Yes. The PFAS Watchlist shows official EPA UCMR 5 monitoring results for public water systems nationwide. Search by utility name, PWSID, or browse by state. Results show detected compounds, concentrations, and sample dates.
How often is this data updated?
Violation and utility data from EPA SDWIS is ingested on a rolling basis. PFAS monitoring records reflect the UCMR 5 dataset covering the 2023–2025 monitoring period. Each report page shows a last-updated date and links to the original government source.

Treatment Guidance
A Practical Guide, Not a Product Grid
Not all filters solve all problems. These guides are educational — they describe what each technology addresses, not a recommendation to buy anything specific.
Photograph needed:
An accurate under-sink reverse-osmosis system or comparable treatment hardware, shown plainly without branding unless licensed.
Reverse Osmosis
Reverse osmosis (RO) is the most comprehensive point-of-use water treatment technology available for residential use. It removes 90–99% of dissolved contaminants including PFAS, lead, arsenic, nitrates, and disinfection byproducts by forcing water through a semi-permeable membrane with pores of approximately 0.0001 microns.
Addresses:
Activated Carbon
Activated carbon is the most widely used residential water treatment technology. It removes chlorine, taste and odor compounds, disinfection byproducts, many volatile organic compounds (VOCs), and — with NSF/ANSI 53 certification — lead and some PFAS. It is available as pitcher filters, under-sink units, and whole-house systems.
Addresses:
Water Softener
A salt-based water softener is the standard whole-home solution for hard water. It uses ion exchange to replace dissolved calcium and magnesium — the minerals responsible for scale, soap scum, and appliance damage — with sodium ions. Softeners protect plumbing and appliances but do not address health-based contaminants.

Built on Official Data
What We Use and What We Won't
Water Utility Report is built entirely on official U.S. government datasets and public regulatory records. We do not scrape competitor databases, republish third-party certification data without authorization, or publish content that hasn't been reviewed for accuracy.
Every data point preserves its source provenance, ingestion date, and confidence level. We separate what the data says from what it means — and we tell you which is which.
Utility identification, service area, and violation history
State-reported on rolling schedules — a gap can reflect reporting lag, not a clean record
Annual utility-published CCR data where available
Not every utility publishes a CCR in a format that can be linked directly
PFAS monitoring records for the 2023–2025 sampling period
Monitoring records only — a detection is not a compliance determination
Supporting sampling data where terms allow public use
Coverage varies by state and monitoring program
