What this data is and is not

Northfield'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 Northfield's customers' taps is household plumbing, invisible to a system-level record ranked 11,329th of 12,903 by violation count. The guide to what this data misses covers that gap.
