What Mahtomedi's record does not cover

Mahtomedi'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 Mahtomedi's customers' taps is household plumbing, invisible to a system-level record ranked 11,656th of 12,903 by violation count. The guide to what this data misses covers that gap.
