What kind of problem, specifically
SYCAMORE'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:
- Radionuclides - flagged from: Combined Radium (-226 and -228)
- Other regulated metals - flagged from: Barium
The most severe category on record is radionuclides, which points toward a reverse osmosis-class filter if you want to address it directly.
What this data is and is not
This is what SYCAMORE 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. This record - 31 health-based violations on file for SYCAMORE - stops at the meter and cannot see household plumbing on the other side of it. The guide to what this data misses covers that gap.
