The concern categories on record
Farallon'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); Interim Enhanced Surface Water Treatment Rule
- Synthetic organic chemicals / pesticides / VOCs - flagged from: Carbon, Total
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 Farallon's record does not cover
Farallon'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 158 logged violations can see. The guide to what this data misses covers that gap.
