The concern categories on record
LAJAS'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: Coliform (TCR); Interim Enhanced Surface Water Treatment Rule; Surface Water Treatment Rule
- Synthetic organic chemicals / pesticides / VOCs - flagged from: CARBON, TOTAL
- Disinfection byproducts - flagged from: TTHM; 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 LAJAS's record does not cover
This is what LAJAS 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 185 logged violations can see. The guide to what this data misses covers that gap.
