Why "no violations" needs a caveat here

WILLOW GROVE MILL serves 3,090 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 WILLOW GROVE MILL's own reported record under the Safe Drinking Water Act - a regulatory filing, not a sample of your tap. Between the utility's meter and WILLOW GROVE MILL's customers' taps is household plumbing, invisible to a system-level record ranked 12,823th of 12,903 by violation count. The guide to what this data misses covers that gap.
