What this data is and is not

Everything on this page is Chisholm'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 Chisholm's customers' taps is household plumbing, invisible to a system-level record ranked 12,440th of 12,903 by violation count.
