Why "no violations" needs a caveat here

WAIOHINU-NAALEHU serves 2,948 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

WAIOHINU-NAALEHU'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 WAIOHINU-NAALEHU - 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.
