Description:
The U.S. Environmental Protection Agency (U.S.EPA) is:currently attempting to balance the complex tradeoff in chemical and microbial risk associated with controlling disinfection and disinfection by-products (D/DBP) in drinking water. n attempting to achieve this balance, the U.S. EPA will propose three rules: an information collection (ICR); an enhanced surface water treatment rule (ESWTR) and a two-stage D/DBP rule. ontrolling D/DBP will have a major impact on drinking water utilities in the United States. here are several options for D/DBP control including moving the point of disinfection, removal of by-products once they are found, removing precursor material or natural organic matter before it interacts with the disinfectant or use of a disinfectant that minimizes the formation of by-products. he least expensive approach to D/DBP control is to move the point of disinfection or the use of an alternative disinfectant. he least desirable approach is to remove disinfection by-products once they are formed. verall, the most effective approach to D/DBP control is to remove precursor before it reacts with the disinfectant. he choice of any given strategy is very site specific.
