What kind of problem, specifically
MATRULLA'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
- Synthetic organic chemicals / pesticides / VOCs - flagged from: CARBON, TOTAL
- Disinfection byproducts - flagged from: Total Haloacetic Acids (HAA5)
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 this data is and is not
Everything on this page is MATRULLA'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 62 logged violations can see. The guide to what this data misses covers that gap.
