What kind of problem, specifically
LEBANON'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: Long Term 2 Enhanced Surface Water Treatment Rule
- Synthetic organic chemicals / pesticides / VOCs - flagged from: Atrazine
- Disinfection byproducts - flagged from: TTHM
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
LEBANON's numbers here come from its own required reporting to EPA under the Safe Drinking Water Act, not from an independent test of your glass of water. Between the utility's meter and LEBANON's customers' taps is household plumbing, invisible to a system-level record ranked 3,226th of 12,903 by violation count. The guide to what this data misses covers that gap.
