What UNION WSC's record does not cover
Everything on this page is UNION WSC'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 UNION WSC's customers' taps is household plumbing, invisible to a system-level record ranked 2,157th of 12,903 by violation count.
