SINGAPORE - Investigations into the fish die-off and pinkish-purple colour of the Sentosa South Cove waterway earlier this month have found that it was caused by the recent weeks heavy and persistent rainfall that altered water conditions.
Water samples tested had low levels of salinity and dissolved oxygen, which may have led to the dead fish sighted on the waterway banks from Jan 6 to Jan 9, said the Sentosa Development Corporation (SDC) and National Environment Agency (NEA) in a joint statement on Sunday (Jan 17).
The algal bloom that changed the colour of the waters was likely triggered by a high nutrient level and organic content in the water, NEA added.

SINGAPORE, Jan 14 In what one resident called an “environmental disaster” at his doorstep, waters at a canal in Sentosa Cove turned pink as it continued to emit a foul sewage-like smell from Tuesday.
This was a week after scores of fishes in the waterway started going belly-up.
Up until yesterday, the mystery remains unsolved while residents there are still disturbed by why this has happened.

The waterway running through Sentosa South Cove has turned an unnatural pinkish-purple since Tuesday afternoon, alarming residents.
Warning signs emerged on Jan 5 when a foul, sewage-like smell came from the waterway.
As the odour became stronger over the next few days, dead fish were found near the banks from last Wednesday to Sunday.
Saturday saw the largest clean up and haul of dead fish, said Knight Frank Property Asset Management on behalf of Sentosa Cove Resort Management (SCRM), in a letter sent to residents on Monday, which was seen by The Straits Times.
