What is a consequence of the reaction between chlorine and organic matter in water?

The reaction between chlorine and organic matter in water leads to the formation of disinfection byproducts, with trihalomethanes being one of the most significant classes. When chlorine is added to water containing organic material, it reacts to create compounds like chloroform, bromoform, and other trihalomethanes. These compounds are of concern because they are harmful to human health and can pose risks if consumed in drinking water over long periods.

Understanding this reaction is important for operators as it highlights the need for careful monitoring and control of both chlorine dosing and organic matter levels in the water treatment process. Operators must balance effective disinfection with minimizing the formation of these undesirable byproducts, ensuring both safety and compliance with regulatory standards.

The other options do not correctly represent the chemical interactions or outcomes associated with the chlorination of water containing organic matter. For example, the increase in pH does not typically occur as a direct result of this reaction, and neither does boosting the mineral content or decreasing turbidity, which are related to different processes in water treatment.
