Does Trenton NJ use chlorine or chloramine for disinfection?
Trenton uses chloramine as the primary disinfectant with a residual level of 1.8 ppm. Chloramine is harder to remove than free chlorine and requires a catalytic carbon or reverse osmosis filter. Standard Brita-style pitchers will NOT remove chloramine.

Has PFAS been found in Trenton NJ drinking water?
PFAS testing data for Trenton is incomplete or pending under EPA UCMR5 monitoring. Check your utility CCR report for the latest results. A certified filter provides precautionary protection.
What is the best water filter for Trenton?
