The concern categories on record
WATSEKA'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:
- Lead & copper - flagged from: Lead and Copper Rule
- Microbial contamination / treatment technique - flagged from: Coliform (TCR)
- Other regulated metals - flagged from: Arsenic
The most severe category on record is lead & copper, which points toward a lead-class filter if you want to address it directly.
What WATSEKA's record does not cover
This is what WATSEKA reported to its state primacy agency and EPA under the Safe Drinking Water Act - real regulatory record, not a lab test of your specific tap. This record - 9 health-based violations on file for WATSEKA - 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.
