Although hundreds of DBPs have occurred in drinking water, only 11 are currently regulated: four trihalomethanes (THMs), five haloacetic acids (HAAs), bromate, and chlorite. ​U.S. regulations have established maximum contaminants levels (MCLs) for these DBPs to limit consumer exposure and protect public health. In addition to a brief overview of these regulated DBPs, this section will address occurrence, formation, health effects, regulations, and analytical and monitoring methods. ​ ​ ​
