The concern categories on record
Wyoming'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)
The most severe category on record is radionuclides, which points toward a reverse osmosis-class filter if you want to address it directly.
What Wyoming's record does not cover
Everything on this page is Wyoming'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 6 logged violations can see. The guide to what this data misses covers that gap.
