What kind of problem, specifically
SCHILLER PARK'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:

- 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 this data is and is not
This is what SCHILLER PARK 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 18 logged violations can see. The guide to what this data misses covers that gap.
