< Select from the sidebar to view information on another rule.
The US Environmental Protection Agency is proposing the Long Term 2 Enhanced Surface Water Treatment Rule to reduce diseases associated with Cryptosporidium and other disease-causing microorganisms in drinking water. The Rule will supplement existing regulations by requiring additional Cryptosporidium treatment at higher risk water suppliers. This regulation also helps to ensure that suppliers maintain protection against microorganisms as they take steps to reduce the formation of disinfection byproducts.
