THE PUBLIC RECORD, MADE READABLE

What does the EPA record say about your water system?

Search 11,440 active community water systems. See compliance flags, source water, inspection history, and the exact rules or contaminants listed in EPA's public export.

Coverage: active community systems reporting 2,500+ people served · snapshot September 13, 2026

01 / READ THE RECORD

Five signals. Kept separate on purpose.

A monitoring violation is not the same thing as a health-based violation. Tap Water Ledger never collapses them into an invented score.

H

Health-based

EPA's export identifies a current violation associated with a health-based requirement.

M

Monitoring & reporting

Required sampling, reporting, or recordkeeping appears in the current record.

N

Public notice

A public-notification requirement is marked in the current export.

O

Other

A different current compliance category is present and remains visibly separate.

S

Serious violator

The current EPA serious-violator flag is shown exactly as its own signal.

03 / PROVENANCE

Every page leads back to the source.

The ledger is built from EPA's public SDWA system-search download. Each system report carries its federal PWSID, the export date, field-level explanations, and a link to the EPA Detailed Facility Report when supplied.
