Several powerful oxidising agents are used in disinfecting and treating drinking water, and many of these also cause the formation of DBPs. Ozone, for example, produces ketones, carboxylic acids, and aldehydes, including formaldehyde. Bromide in source waters can be converted by ozone into bromate, a potent carcinogen that is regulated in the United States, as well as other brominated DBPs.

As regulations are tightened on established DBPs such as THMs and HAAs, drinking water treatment plant may switch to alternative disinfection methods. This change will alter the distribution of classes of DBP's.
