The concern categories on record

KESHENA'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 KESHENA's record does not cover

This is what KESHENA 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 KESHENA - 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.
