In order to comply with the regulations for disinfection byproducts, many utilities are
utilizing alternative disinfectants, such as chlorine dioxide (ClO2) and chloramines, and are
minimizing free chlorine (Cl2) contact time. This study investigated the ability or inability of
ClO2, Cl2, and potassium permanganate to oxidize fishy/swampy/grassy odorants, and powdered
activated carbon (PAC) to adsorb these compounds. ClO2 was found to be a selective oxidant
for the control of these types of taste-and-odor problems, whereas maintaining some free Cl2
contact time (e.g., through the filters) or use of permanganate or PAC may be needed if prechlorination
is eliminated. Includes 12 references, table, figures.
