Why "no violations" needs a caveat here

HARRIS COUNTY MUD 558 serves 3,300 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

Everything on this page is HARRIS COUNTY MUD 558's own reported record under the Safe Drinking Water Act - a regulatory filing, not a sample of your tap. Water quality can still change between the meter and the faucet - household plumbing sits outside what a record of 0 logged violations can see. The guide to what this data misses covers that gap.
