What kind of problem, specifically

CAIRO'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)
• Other regulated metals - flagged from: Arsenic

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 this data is and is not

CAIRO'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 CAIRO - 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.
