- Microbial contamination / treatment technique - flagged from: Coliform (TCR); Groundwater Rule
The most severe category on record is microbial contamination / treatment technique, which points toward a microbial-class filter if you want to address it directly.
What REGIONAL WATER's record does not cover
REGIONAL WATER'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. Between the utility's meter and REGIONAL WATER's customers' taps is household plumbing, invisible to a system-level record ranked 3,754th of 12,903 by violation count. The guide to what this data misses covers that gap.
