- Synthetic organic chemicals / pesticides / VOCs - flagged from: CARBON, TOTAL

What YAUCO's record does not cover
This is what YAUCO 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 - 24 health-based violations on file for YAUCO - 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.
