What are trihalomethanes?

• A. Chemicals used to dechlorinate water
• B. Chemicals used to clean pumps
• C. Disinfection by-products
• D. Chemicals used to remove scaling

Answer: (C)

Trihalomethanes are a group of chemical compounds that are formed as by-products during the disinfection of drinking water, particularly when chlorine is used as a disinfectant. When chlorine reacts with natural organic matter present in water, it can lead to the formation of trihalomethanes. These disinfection by-products are of concern because they have been associated with potential health risks, including cancer and other adverse health effects, which is why water treatment procedures often include measures to minimize their formation. Understanding the nature and implications of trihalomethanes is crucial for water quality management and compliance with health regulations. In contrast, the other choices pertain to various processes or substances not related to the formation of trihalomethanes. For instance, the roles described in options regarding dechlorination, cleaning, and scaling removal do not involve the formation of trihalomethanes, highlighting their distinct functions and properties within water treatment and distribution systems.
