Pasir Ris Residents Concerned Over Possible Pollution After Spotting Foamy Water That This Monitor Lizard Was Soaking In

The video quickly drew concerned reactions online, with some agreeing that they had seen the soap-like foam appear from time to time.

Several also called for investigations into where the foam was coming from and whether it posed any risk to wildlife.

At the moment, it remains unclear what has caused the white foamy residue in the river.

It is also unknown whether the substance poses any risk to the monitor lizard or other animals living in and around the waterway.

Not all foam found in waterways is necessarily caused by pollution.

In some cases, naturally occurring organic matter can also produce foam under certain conditions.

In response to queries from 8days.sg, the National Environment Agency (NEA) said it deployed officers to investigate after being alerted to the video posted on the Singapore Wildlife Sightings Facebook page on July 5.

According to the agency, officers found no unusual discharge at Sungei Api Api or in the nearby drains. NEA also said there were no reports of water pollution in the surrounding area.

Nevertheless, the agency has reminded the management of nearby residential developments, as well as resident networks and schools in the vicinity, to ensure that their activities do not result in the discharge of soapy water or other polluting substances into public drains.

NEA also encouraged members of the public who come across unusual discharges into waterways to report them via the OneService app. When making a report, the agency advises providing the exact location, date and time of the incident, together with photos or videos to facilitate investigations.
