The concern categories on record
ROCHELLE'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)
- Radionuclides - flagged from: Combined Radium (-226 and -228)
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 ROCHELLE's record does not cover
This is what ROCHELLE 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. Between the utility's meter and ROCHELLE's customers' taps is household plumbing, invisible to a system-level record ranked 1,808th of 12,903 by violation count. The guide to what this data misses covers that gap.
