What PLANO's record does not cover

Everything on this page is PLANO'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 PLANO's customers' taps is household plumbing, invisible to a system-level record ranked 10,066th of 12,903 by violation count. The guide to what this data misses covers that gap.
