The concern categories on record
OSU WATER PLANT'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); Surface Water Treatment Rule
- Disinfection byproducts - flagged from: TTHM
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 OSU WATER PLANT's record does not cover
OSU WATER PLANT'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 33 logged violations can see. The guide to what this data misses covers that gap.
