What this data is and is not
MANVILLE WSC's numbers here come from its own required reporting to EPA under the Safe Drinking Water Act, not from an independent test of your glass of water. This record - 6 health-based violations on file for MANVILLE WSC - 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.
