Summary
Chloramination and disinfection byproducts (DBPs) in water
Answer
DBPs are produced by the reaction of chlorine with organic matter occurring in the water. Using monochloramine formed by pre-reaction of the chlorine with ammonia lessens the formation potential of DBPs. However, chloramination is not the solution for DBPs that it was once believed. Research indicates that other DBPs (i.e.nitrosodimethylamine, NDMA) are generated by the chloramination process. These resulting DBPs from chloramination are under further investigation to determine if there are any negative health impacts.
