The concern categories on record

RAYO's flagged contaminants and rule violations, grouped by what they actually mean for a filter choice rather than left as EPA's raw code list:

• Microbial contamination / treatment technique - flagged from: Coliform (TCR)

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 RAYO's record does not cover

RAYO'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 - 9 health-based violations on file for RAYO - 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.
