The concern categories on record

What CIALES URBANO's record does not cover
This is what CIALES URBANO 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. Water quality can still change between the meter and the faucet - household plumbing sits outside what a record of 165 logged violations can see. The guide to what this data misses covers that gap.
