What kind of problem, specifically
ALTO'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 Uranium
- Nitrate / nitrite - flagged from: Nitrate
- Synthetic organic chemicals / pesticides / VOCs - flagged from: Benzene
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 this data is and is not
Everything on this page is ALTO's own reported record under the Safe Drinking Water Act - a regulatory filing, not a sample of your tap. This record - 13 health-based violations on file for ALTO - 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.
