What is a common mitigation approach for disinfection byproducts (DBPs) in drinking water?

• A. Increase The Disinfectant Dose Without Monitoring
• B. Boiling The Water After Distribution
• C. Source Water Protection, Optimization Of Disinfectant Dosing, And Alternative Disinfectants
• D. Remove Disinfectants Completely

Answer: (C)

Disinfection byproducts form when disinfectants react with natural organic matter and other precursors in water, so reducing their formation requires a multi-pronged strategy that targets the source, how disinfection is applied, and the choice of disinfectant itself. Protecting the source water minimizes the amount of organic material available to form DBPs, often through watershed management and intake protection. Optimizing disinfectant dosing means using the smallest effective dose with appropriate contact time and treatment controls to prevent excess residuals that drive DBP production. Using alternative disinfectants or combinations—such as switching to chloramines or UV treatment when feasible—can lower the specific DBPs produced while still ensuring microbial safety. Together, these elements reflect a practical, commonly used approach to mitigate DBPs in drinking water.
