What kind of problem, specifically
LOMBARD'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 this data is and is not
Everything on this page is LOMBARD'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 5 logged violations can see. The guide to what this data misses covers that gap.
