What are the effects of high chlorine levels in treated water?

High chlorine levels in treated water can lead to significant health risks and potential irritation for consumers. Chlorine, while effective as a disinfectant in water treatment to eliminate pathogens, can have negative effects when present in excessive amounts.

When chlorine levels exceed safe drinking water standards, it can cause a range of health issues, including respiratory problems, skin irritation, and gastrointestinal discomfort. Additionally, chlorine can react with organic matter in water to form disinfection byproducts, some of which are harmful and have been linked to serious health concerns, including cancer.

While proper chlorine levels can improve the taste and odor of water, excessive chlorine usually results in a distinctly unpleasant taste and smell, contradicting the choice that implies an improvement. Increased water clarity is not directly correlated with high chlorine levels; rather, clarity typically pertains to the absence of particulates and is more associated with filtration processes. Lastly, while chlorine is a cost-effective disinfectant, excessively relying on it does not necessarily lead to decreased overall water treatment costs, as potential health issues may require additional monitoring and remedial action.
