The concern categories on record
CHESTER WATER DEPT.'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: Interim Enhanced Surface Water Treatment Rule; Long Term 2 Enhanced Surface Water Treatment Rule; Stage 1 Disinfectants and Disinfection Byproducts Rule; Surface Water Treatment Rule
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 CHESTER WATER DEPT.'s record does not cover
CHESTER WATER DEPT.'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. Water quality can still change between the meter and the faucet - household plumbing sits outside what a record of 102 logged violations can see. The guide to what this data misses covers that gap.
