Optimization to achieve turbidity (particulate) performance goals has been the primary focus of the
Composite Correction Program (CCP) since implementation of the Surface Water Treatment Rule in the
early 1990s. The recent implementation of the Stage 1 Disinfectants/ Disinfection Byproducts Rule
for large systems and small systems (2004) has introduced new challenges associated with achieving
multiple water quality objectives for water utilities. This paper describes the ongoing development and
demonstration activities associated with incorporating disinfection and disinfection byproduct
performance goals and control strategies into the CCP protocol. The work, supported by the Center for
Drinking Water Optimization and USEPA's Technical Support Center, is a collaboration of research
efforts and field investigations conducted at nine water utilities since 2000. All of the water treatment
plants utilize conventional surface water treatment processes, including chlorine as their primary
disinfectant and either chlorine or chloramines as their secondary disinfectant. Includes 5 references, tables, figures.
