Common Concerns

What Are People Checking?

These contaminants appear most frequently in U.S. public water systems and generate the most consumer questions.

high risk level

PFAS

Synthetic Chemicals

PFAS are a group of thousands of man-made chemicals that have been used in industrial and consumer products since the 1940s. They do not break down in the environment or the human body, earning the name 'forever chemicals.' In April 2024, the EPA set the first-ever federal limits for six PFAS compounds in drinking water.

high risk level

Lead

Heavy Metals

Lead enters drinking water primarily through corrosion of lead service lines and lead-containing plumbing fixtures — not typically from the water source itself. There is no safe level of lead exposure for children. The EPA's 2024 Lead and Copper Rule Improvements require utilities to replace all lead service lines within 10 years.

Lead records and treatment options
moderate risk level

Nitrates

Agricultural Chemicals

Nitrates are colorless, odorless compounds that occur naturally in soil but reach dangerous levels in water primarily from agricultural fertilizer runoff and septic system leakage. They pose an acute, potentially fatal risk to infants under 6 months and are increasingly linked to cancer risk even at levels below the EPA's 10 mg/L limit. An estimated 62 million Americans drink water with nitrate levels above 3 mg/L.

DBPs

Disinfection Byproducts

Disinfection byproducts form when chlorine or other disinfectants react with naturally occurring organic matter in source water. The two main regulated groups are total trihalomethanes (TTHMs) and haloacetic acids (HAA5). They are an unavoidable tradeoff of water disinfection — the risk of not disinfecting far outweighs the risk of DBPs, but minimizing exposure is prudent.

Government Data Watchlist

PFAS in Your Drinking Water

Track official EPA UCMR 5 PFAS monitoring records for public water systems nationwide. Every record is sourced from government data — no risk scores, no estimates, no guesswork.

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.

Matched treatment guidance, official report links, certified labs, and clear next steps.

Treatment Guidance

Find the Right Filter

Not all filters solve all problems. Matched treatment guides tell you exactly what each technology removes.

Under-sink / countertop

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:

PFAS / PFOA / PFOS — 90–99% removalLead — 95–99% removalArsenic — 90–95% removal
Point-of-use or whole-home

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:

Chlorine and chloramine — virtually complete removalTaste and odor compounds — highly effectiveDisinfection byproducts
Whole-home

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.

Addresses:

Scale buildup in pipes, water heaters, and appliancesSoap and shampoo lathering — softened water requires significantly less soapSpots on dishes, glassware, and shower doors

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.
