What CWS - VISALIA's record does not cover

CWS - VISALIA'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 CWS - VISALIA's customers' taps is household plumbing, invisible to a system-level record ranked 7,047th of 12,903 by violation count. The guide to what this data misses covers that gap.
