This powerpoint presentation begins by providing a brief overview of climate change. 20th century climate variability is presented, along withpotential impacts to distribution system waterquality. Presentation summary includes the following: climate change over the 21st centurywill likely affect distribution systemwater quality in areas ofdisinfection residual control,increased disinfection byproduct (DBP) formation,corrosion control, andnitrification control; climate change has the potential toaffect seasonal distribution systemwater quality in areas such aswater temperature,salinity (in tidal influenced sources),disinfection byproducts, andtaste and odor related parameters; and, adaptation to climate change should beconsidered to maintain distributionsystem water quality related toeffectiveness of flushing program,effectiveness of corrosion control program, andoptimization of disinfectant-DBP controlstrategies. Includes figures.
