R--Technical Support for Drinking Water Optimization Program

on of the Drinking Water Composite Correction Program (CCP). Implementation of the CCP resulted in documented improvements on individual surface water treatment plant performance. The documented success of the CCP, its value for drinking water primacy programs and the desire to apply CCP principles more broadly resulted in the creation of an Area-wide Optimization Program (AWOP). Broad-scale public water system performance improvements and the resulting drinking water quality improvements have been achieved via AWOP implementation. Public Water System Supervision (PWSS) programs implement their AWOPs to enhance public health protection and to benefit from the resulting proactive assistance with regulatory compliance. The AWOP was established with a focus on turbidity removal, resulting in greater protection against the risk of microbial pathogens passing through treatment plant processes. The program continues the focus on turbidity removal while expanding its technical scope to include optimization of both treatment plant and distribution system operations to minimize the formation of disinfection by-products (DBPs) and maintaining adequate disinfectant residual. The technical scope of the program also includes optimization of process control for ground water treatment and conveyance, and many unconventional (alternate) treatment processes. The program�s documented impact on enhancing public health protection has also been called upon to address other public health challenges such as treatment for cyanobacteria associated with harmful algal blooms and arsenic removal. The National AWOP has been structured to address additional public health challenges, depending on the commitment of resources to the program.
