In order to comply with the regulations for disinfection byproducts, many utilities are
utilizing alternative disinfectants, such as chlorine dioxide (ClO<sub>2</sub>) and chloramines, and are
minimizing free chlorine (Cl<sub>2</sub>) contact time. This study investigated the ability or inability of
ClO<sub>2</sub>, Cl<sub>2</sub>, and potassium permanganate to oxidize fishy/swampy/grassy odorants, and powdered
activated carbon (PAC) to adsorb these compounds. ClO<sub>2</sub> was found to be a selective oxidant
for the control of these types of taste-and-odor problems, whereas maintaining some free Cl<sub>2</sub>
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.
