S’pore scientists studying if chemical found in tap water is harmful to health

Chlorine and other types of disinfectants kill harmful bacteria and viruses, and are used to ensure that tap water remains pathogen-free and safe to drink.

Scientists are studying whether a chemical compound found in minute traces in tap water here could be harmful if ingested in larger amounts.

There is currently no cause for concern, said national water agency PUB, and further research will need to be conducted to ascertain the health risks of such additives. Professor Shane Snyder, Nanyang Environment and Water Research Institute (NEWRI)’s Executive Director at Nanyang Technological University (NTU), said: “The DPG-chlorine by-product is not an immediate cause for concern in Singapore, as the concentrations found in tap water here were much lower than what would be expected in other countries."
