Chlorination is the most important process in the production of ______________ water.

• A. Raw
• B. Potable
• C. Treated
• D. Distilled

Answer: (B)

Disinfection to ensure drinking-water safety is the main idea behind chlorination in water treatment. After the water has undergone processes to remove particles and contaminants, chlorine is added to kill bacteria, viruses, and other pathogens. This step is crucial because it directly lowers the risk of waterborne illness and provides a residual protective level as water travels through the distribution system, helping prevent recontamination. Distilled water is produced by boiling and condensing water, not by chlorination, and raw water isn’t safe to drink without disinfection. Treated water may involve chlorination, but the key reason it becomes potable is the disinfection that chlorine provides.
