What is a potential health risk associated with chlorine use in water treatment?

Increase in dissolved oxygen levels
Formation of trihalomethanes
Reduction of conductivity
Decrease in microbial resistance

The correct answer is: Formation of trihalomethanes

The formation of trihalomethanes (THMs) is a well-documented health risk associated with the use of chlorine for water treatment. When chlorine is added to water, especially when it reacts with organic matter present in the source water, it can lead to the production of THMs. These compounds are considered carcinogenic and may pose various health risks, including an increased likelihood of certain cancers and other adverse health effects over long-term exposure. Understanding this risk emphasizes the importance of monitoring chlorine levels and the presence of organic materials in the source water to minimize the formation of THMs. Water treatment facilities must implement strategies to reduce the concentration of these byproducts while still effectively disinfecting the water to ensure it is safe for consumption.
