What this data is and is not

This is what PRYOR reported to its state primacy agency and EPA under the Safe Drinking Water Act - real regulatory record, not a lab test of your specific tap. Between the utility's meter and PRYOR's customers' taps is household plumbing, invisible to a system-level record ranked 2,471th of 12,903 by violation count. The guide to what this data misses covers that gap.
