Why "no violations" needs a caveat here

HARRIS COUNTY MUD 434 serves 2,859 people. EPA requires smaller systems to test less often than large ones, so a clean record here is real but weaker evidence than the same record on a system serving hundreds of thousands - fewer tests means fewer chances to catch a problem. See the guide to reading a clean record for what that does and does not tell you.

What HARRIS COUNTY MUD 434's record does not cover

This is what HARRIS COUNTY MUD 434 reported to its state primacy agency and EPA under the Safe Drinking Water Act - real regulatory record, not a lab test of your specific tap.
