The concern categories on record
CARBON CLIFF'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 CARBON CLIFF's record does not cover
CARBON CLIFF'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 32 logged violations can see. The guide to what this data misses covers that gap.
