The concern categories on record
ROCKFORD'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 ROCKFORD's record does not cover
ROCKFORD'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. Water quality can still change between the meter and the faucet - household plumbing sits outside what a record of 48 logged violations can see. The guide to what this data misses covers that gap.
