The concern categories on record
Lonsdale'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); Gross Alpha, Excl. Radon and U
The most severe category on record is radionuclides, which points toward a reverse osmosis-class filter if you want to address it directly.
What Lonsdale's record does not cover
Lonsdale'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 - 2 health-based violations on file for Lonsdale - 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.
