The concern categories on record
ROSELLE'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:
- Radionuclides - flagged from: Combined Radium (-226 and -228)
The most severe category on record is radionuclides, which points toward a reverse osmosis-class filter if you want to address it directly.
What ROSELLE's record does not cover
ROSELLE'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 ROSELLE's customers' taps is household plumbing, invisible to a system-level record ranked 6,475th of 12,903 by violation count. The guide to what this data misses covers that gap.
