Official EPA data, translated
Check the federal drinking water record for the system serving your home.
Enter your address or search by system name, city, or ZIP to see the federal violation record for the public water system that serves you.
21 million Americans are on systems with health-based drinking water violations.
Tap Truth is built for households, renters, homebuyers, and advocates who want to see the official record without reading raw regulatory tables.
Start here
Find your water system in under a minute.
Use your address when you want the fastest answer. Use search when a metro utility, PO Box ZIP, or apartment address is harder to match.
Built from EPA ECHO SDWA downloads.
Tap Truth covers regulated public water systems, not private wells. Works best for addresses outside major metropolitan areas served by large municipal systems.
Finding the utility behind an address
Match a home address to the most likely public water system serving that location.
Reading the federal record in plain English
See health-based violations, monitoring issues, and lead service-line inventory without sorting through EPA codes.
Checking before you move, rent, or recommend
A clean, public-facing way to share the tool itself with neighbors, family, and community groups.
Why people use this
EPA data is public. It is not public-friendly.
Tap Truth turns system IDs, rule codes, and violation categories into a readable public record of what happened, when it happened, and whether the issue was resolved.
Step 1
Enter an address
Geocode the location and identify the public system serving that area.
Step 2
Match the system
Use service-area, ZIP, county, and search-based fallback logic already built into the app.
Step 3
Read the record
Review the official federal history, monitoring issues, and lead pipe inventory in one place.
Trust and limits
Built for public use, not expert-only workflows.
Tap Truth summarizes official EPA drinking water data for public systems. It does not replace lab testing and does not cover private wells.
