MDBP Rules: Implementation Activities

Microbial and disinfection byproducts rules:
Implementation

Disinfection of drinking water is one of the major public health advances of the 20th century.  However, the disinfectants themselves can react with naturally-occurring materials in the water to form unintended byproducts which may pose health risks.  A major challenge for water suppliers is balancing the risks from microbial pathogens and disinfection byproducts. The Stage 1 Disinfectants and Disinfection Byproducts Rule and Interim Enhanced Surface Water Treatment Rule together address these risks.
