The concern categories on record
VOLO'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)
- Other regulated metals - flagged from: Barium
The most severe category on record is radionuclides, which points toward a reverse osmosis-class filter if you want to address it directly.
What VOLO's record does not cover
Everything on this page is VOLO's own reported record under the Safe Drinking Water Act - a regulatory filing, not a sample of your tap. Between the utility's meter and VOLO's customers' taps is household plumbing, invisible to a system-level record ranked 2,662th of 12,903 by violation count. The guide to what this data misses covers that gap.
