What is a potential consequence of high levels of chlorine exposure in water distribution systems?

Taste improvement
Full filtration
Health risks including respiratory issues
Increased bacterial growth

The correct answer is: Health risks including respiratory issues

High levels of chlorine exposure in water distribution systems can lead to significant health risks, particularly respiratory issues. Chlorine is commonly used as a disinfectant in water treatment processes to eliminate harmful bacteria and other pathogens. However, when chlorine levels are excessively high, it can create harmful byproducts and irritants. Long-term exposure or acute inhalation of chlorine gas can contribute to respiratory problems, including asthma exacerbation, bronchitis, and other respiratory distress symptoms. The chlorine can also react with organic matter in the water, forming chlorinated byproducts like trihalomethanes and haloacetic acids, which are associated with various health concerns. Understanding the balance in water treatment is vital; while chlorine is essential for disinfection, it is crucial to monitor and control its levels to ensure safety and minimize health risks.
