What this data is and is not
Everything on this page is LAMAR PWS'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 LAMAR PWS's customers' taps is household plumbing, invisible to a system-level record ranked 705th of 12,903 by violation count. The guide to what this data misses covers that gap.
