The concern categories on record
COMMERCE'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 REVISIONS
- Microbial contamination / treatment technique - flagged from: Coliform (TCR)
The most severe category on record is lead & copper, which points toward a lead-class filter if you want to address it directly.
What COMMERCE's record does not cover
Everything on this page is COMMERCE's own reported record under the Safe Drinking Water Act - a regulatory filing, not a sample of your tap. Water quality can still change between the meter and the faucet - household plumbing sits outside what a record of 111 logged violations can see. The guide to what this data misses covers that gap.
