Hundreds of organic byproducts of chlorination are now known to occur in drinking water along with the trihalomethanes. About twenty of these appear to be found with sufficient frequency and in sufficient concentration to attract consideration for regulations. These include chloral hydrate, chloropicrin, a trichloropropanone, haloacetonitriles, and haloacetic acids. Trihalomethane concentrations do not serve as good predictors of concentrations of these other byproducts because their conditions of formation vary widely. This is especially true when pH is changed. Treatment strategies for control of these byproducts including the trihalomethanes are: Remove the compounds after they are formed; Remove precursors; and Use other disinfectants. Current evidence supports the idea that precursor removal processes effective for trihalomethane control may be effective for the other byproducts as well.
