A man managed to witness mysterious black fluid bubbling out at a rain canal in Potong Pasir last Friday afternoon, and the authorities are still figuring out what happened.
Facebook user Adam Teeoo shared footage of the strange sighting at Potong Pasir Avenue 1, where an outlet drain appeared to be spewing out dark liquid into the canal. The unknown fluid was dark enough to contrast with the rest of the water in the canal.
Though Adam did not make it explicit, pictures he took implied that he believes the construction site next to the canal could be at fault for the mystery discharge.
‘Within normal range’
In response to queries by Channel NewsAsia, the Public Utilities Board (PUB) and the National Environment Agency (NEA) mentioned that they didn’t find anything unusual when they investigated the scene.
Confirming that it was alerted to the incident on Saturday morning, PUB had sent down officers and contractors to investigate the outlet drain immediately. According to them, no discharge was found, while water quality sensors and readings found that everything is “within the normal range”.
PUB will closely monitor the water quality over the next couple of days, while the NEA is conducting their own investigations.
Mystery fluids in canals are rare, but not unheard of — a stretch of canal in Jurong West saw the appearance of blood-red water back in 2015.
