Are there other options for disinfection besides chlorination?

Besides chlorine, there are several other types of disinfectants. Each has tradeoffs. Chloramines may form lower levels of regulated DBPs than chlorine, but, depending on the source water characteristics, they have the potential to form other DBPs and increase the risks of nitrate formation and corrosion in the distribution system. Ozone is effective and has no taste, but it can also create other DBPs and does not provide protection in the distribution system, so chloramines or chlorine must still be added to protect the water. Ultraviolet (UV) light is effective in clear water and does not form DBPs. But like ozone, UV light does not provide protection in the distribution system, so chloramines or chlorine must still be added to protect water from the treatment plant to the tap.
