Removing organic matter, optimizing the amount of chlorine or moving the point of chlorination downstream in the treatment process are accepted methods of reducing the formation of DBPs. However, protection from waterborne illnesses must be the primary concern. Other disinfectants are available, yet none provides the complete range of benefits available from chlorination. Most importantly, chlorine-based disinfectants are the only ones that protect drinking water from the treatment plant all the way to the consumer's tap. Furthermore, in the US people have relied on chlorine for drinking water disinfection for nearly a century.
All chemical disinfectants produce byproducts.
Chlorination byproducts have been well studied compared to the byproducts of alternatives which are just beginning to be studied. Industry is funding research and working with the EPA, the water industry and other interested groups to reduce DPBs without compromising the safety of our water. Fluids are very important during pregnancy and daily consumption of 6 - 8 glasses of water is recommended. U.S. drinking water is regulated to assure that disinfection through chlorination and other processes assures that it is both clean and safe to drink. In the meantime, pregnant women who have questions or concerns should speak with their physicians.
