What CHILLICOTHE's record does not cover

Everything on this page is CHILLICOTHE's own reported record under the Safe Drinking Water Act - a regulatory filing, not a sample of your tap. Between the utility's meter and CHILLICOTHE's customers' taps is household plumbing, invisible to a system-level record ranked 3,030th of 12,903 by violation count. The guide to what this data misses covers that gap.
