The concern categories on record
GURNEE'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)
- Radionuclides - flagged from: Combined Radium (-226 and -228)
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 GURNEE's record does not cover
Everything on this page is GURNEE's own reported record under the Safe Drinking Water Act - a regulatory filing, not a sample of your tap. This record - 4 health-based violations on file for GURNEE - stops at the meter and cannot see household plumbing on the other side of it. The guide to what this data misses covers that gap.
