What FESTUS PWS's record does not cover

This is what FESTUS PWS 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. This record - 1 health-based violation on file for FESTUS PWS - stops at the meter and cannot see household plumbing on the other side of it. The guide to what this data misses covers that gap.
