What this data is and is not
Osseo'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 Osseo's customers' taps is household plumbing, invisible to a system-level record ranked 8,506th of 12,903 by violation count. The guide to what this data misses covers that gap.
