The concern categories on record

- Microbial contamination / treatment technique - flagged from: Coliform (TCR)
- Radionuclides - flagged from: Combined Radium (-226 and -228); Gross Alpha, Excl. Radon and U
- Other regulated metals - flagged from: Fluoride
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 KNOXVILLE's record does not cover
KNOXVILLE'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 KNOXVILLE's customers' taps is household plumbing, invisible to a system-level record ranked 865th of 12,903 by violation count. The guide to what this data misses covers that gap.
