Tests on Water Sources for Presence of Micro-plastics Contamination

21 Mr Edward Chia Bing Hui asked the Minister for Sustainability and the Environment (a) whether the Ministry has tested our national water supply in the last year for micro-plastics contamination levels; and (b) if so, whether the test has been conducted for each of the four national tap sources to ascertain if there are any differences in the presence of micro-plastics.

Ms Grace Fu Hai Yien: PUB has conducted biennial surveillance of the level of micro-plastics in water from our Four National Taps since 2017. The latest testing results in 2021 showed that micro-plastics were not detected.
