What kind of problem, specifically
CONSTANTINE'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:
- Nitrate / nitrite - flagged from: Nitrate
The most severe category on record is nitrate / nitrite, which points toward a reverse osmosis-class filter if you want to address it directly.
What this data is and is not
CONSTANTINE'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 13 logged violations can see. The guide to what this data misses covers that gap.
