Is chlorinated tap water safe? Experts warn of hidden risks in disinfection

Concerns have been raised about the safety of tap water despite ongoing disinfection efforts. Yury Honchar, head of the Main Testing and Inspection Center for Drinking Water, recently highlighted potential risks linked to consumption. His warnings come as experts weigh the trade-offs between water treatment methods and their unintended effects.

One key issue involves chlorination, a standard process used to kill harmful bacteria. While essential for public health, this method can create by-products with long-term risks.

Chlorination remains a cornerstone of water disinfection worldwide. Without it, harmful microbes could spread through water supplies, leading to outbreaks of disease. Yet the process also produces chlororganic compounds, some of which have been classified as carcinogenic.

Honchar's remarks underscore the need for caution, though he did not propose eliminating chlorination. Instead, he suggested that households could take extra steps to improve water quality. Using pitcher filters or other purification systems at home may help reduce unwanted impurities before drinking. No public records exist to show water quality trends in regions under Honchar's oversight over the past five years. His organisation, the Main Testing and Monitoring Center for Drinking Water, lacks documented activity in accessible sources, leaving gaps in data for independent verification.

The debate over tap water safety continues, balancing the necessity of disinfection against potential hazards. Households concerned about contaminants can use additional filtration to lower exposure. For now, chlorination stays in place as a vital tool—despite its known drawbacks.
