Which health issues are associated with the byproducts of drinking water chlorination?

The byproducts of chlorination in drinking water, particularly trihalomethanes (THMs) and haloacetic acids (HAAs), have been studied extensively for their potential health risks. Evidence suggests that long-term exposure to these byproducts might increase the risk of developing cancers, such as bladder and colorectal cancer. Additionally, certain chlorination byproducts have been linked to reproductive health issues, including adverse pregnancy outcomes and developmental concerns in offspring.

Understanding the significance of these health risks is crucial for water treatment plants and public health agencies, as they must balance the benefits of chlorination—namely, the effective reduction of pathogens in water—with minimizing exposure to harmful byproducts. Options addressing respiratory issues, skin irritations, and sore throat are less directly linked to chlorination byproducts in drinking water, making them less relevant in the context of this question.
