What kind of problem, specifically
CASEY'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
- Microbial contamination / treatment technique - flagged from: Coliform (TCR)
- Nitrate / nitrite - flagged from: Nitrite
The most severe category on record is lead & copper, which points toward a lead-class filter if you want to address it directly.
What this data is and is not
Everything on this page is CASEY'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 39 logged violations can see. The guide to what this data misses covers that gap.
