• Microbial contamination / treatment technique - flagged from: Coliform (TCR)

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 MAGUAYO's record does not cover

This is what MAGUAYO 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. Between the utility's meter and MAGUAYO's customers' taps is household plumbing, invisible to a system-level record ranked 2,280th of 12,903 by violation count. The guide to what this data misses covers that gap.
