What's in TULSA's water?

Ranked against every other system in this dataset
28 total violations and 2 health-based ones put TULSA at the 53th percentile nationally for violation burden, rank 6,086 of 12,903.

The concern categories on record
TULSA'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: Surface Water Treatment Rule
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 TULSA's record does not cover
This is what TULSA 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 28 logged violations can see. The guide to what this data misses covers that gap.
