Abstract

This project assists utilities in determining whether it is feasible to utilize existing GAC filter caps to (1) help meet DBP regulations through control of DBP precursors, (2) remove selected classes of trace organic contaminants, and (3) provide a barrier against deliberate contaminants. The project also helps utilities plan GAC replacement frequencies to optimize seasonal contaminant removal. Published in 2012.
