The concern categories on record

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 LEFT HAND WD's record does not cover
This is what LEFT HAND WD 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 70 logged violations can see. The guide to what this data misses covers that gap.
