The concern categories on record

- Microbial contamination / treatment technique - flagged from: Interim Enhanced Surface Water Treatment Rule; Long Term 2 Enhanced Surface Water Treatment Rule; Surface Water Treatment Rule
- Disinfection byproducts - flagged from: Total Haloacetic Acids (HAA5)
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 DUEY's record does not cover
Everything on this page is DUEY's own reported record under the Safe Drinking Water Act - a regulatory filing, not a sample of your tap. Water quality can still change between the meter and the faucet - household plumbing sits outside what a record of 124 logged violations can see. The guide to what this data misses covers that gap.
