The concern categories on record
VANDALIA'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)
- 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 VANDALIA's record does not cover
VANDALIA'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. Between the utility's meter and VANDALIA's customers' taps is household plumbing, invisible to a system-level record ranked 6,301th of 12,903 by violation count. The guide to what this data misses covers that gap.
