Why "no violations" needs a caveat here

MONTGOMERY COUNTY MUD 139 serves 5,523 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 MONTGOMERY COUNTY MUD 139's record does not cover

MONTGOMERY COUNTY MUD 139'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. Between the utility's meter and MONTGOMERY COUNTY MUD 139's customers' taps is household plumbing, invisible to a system-level record ranked 12,733th of 12,903 by violation count. The guide to what this data misses covers that gap.
