A survey was conducted to determine practices and problems associated with the use of chlorine dioxide (ClO 2 ) by US water utilities. The survey acquired data concerning raw‐ and finished‐water quality as well as treatment processes. A specific emphasis of the survey was to investigate the association of adverse odors (particularly those resembling kerosene and cat urine) with ClO 2 application. The results indicate that ClO 2 is primarily applied to reduce the formation of trihalomethanes. Offensive odors associated with the application of ClO 2 were not correlated with raw‐ or finished‐water quality. Odors were more intense and more diverse when ClO 2 was used, and increased numbers of complaints about odors were associated with the presence of new carpets in customers' homes.
