This powerpoint presentation presents a study to document the long-term effects of
disinfectant changes on distribution
system water quality. A literature search was done, and 26 utilities in 15 states, Washington, D.C., and British Columbia were surveyed on changes in disinfection practices including: chlorine to chloramines;
chlorine to ozone;
chlorine to chlorine dioxide;
chlorine to ultraviolet (UV); and,
adding booster chlorination. The presentation provides information on the impact that each of these disinfection practices has on water quality, disinfection byproducts, microbes, corrosion, and aesthetics. Potential applications include: evaluating current changes;
making operational adjustments;
considering future changes;
designing future changes; and,
diagnosing water quality problems.
