The concern categories on record
HAZEL CREST'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)
The most severe category on record is lead & copper, which points toward a lead-class filter if you want to address it directly.
What HAZEL CREST's record does not cover
HAZEL CREST'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 HAZEL CREST's customers' taps is household plumbing, invisible to a system-level record ranked 6,577th of 12,903 by violation count. The guide to what this data misses covers that gap.
