What COLUMBUS LIGHT & WATER's record does not cover
COLUMBUS LIGHT & WATER'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 COLUMBUS LIGHT & WATER's customers' taps is household plumbing, invisible to a system-level record ranked 5,930th of 12,903 by violation count. The guide to what this data misses covers that gap.
