The concern categories on record
HARVARD'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:
- Lead & copper - flagged from: Lead and Copper Rule
- Microbial contamination / treatment technique - flagged from: Coliform (TCR)
The most severe category on record is lead & copper, which points toward a lead-class filter if you want to address it directly.
What HARVARD's record does not cover
HARVARD'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 19 logged violations can see. The guide to what this data misses covers that gap.
