What this data is and is not
This is what Perham 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 Perham - 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.
