Why "no violations" needs a caveat here

HARRIS COUNTY MUD 457 serves 5,967 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 this data is and is not

HARRIS COUNTY MUD 457's numbers here come from its own required reporting to EPA under the Safe Drinking Water Act, not from an independent test of your glass of water. This record - 0 health-based violations on file for HARRIS COUNTY MUD 457 - stops at the meter and cannot see household plumbing on the other side of it. The guide to what this data misses covers that gap.
