STOMPer Tan is pleased that the Bishan Park canal no longer stinks. NEA reportedly told the STOMPer that they have identified the source of the sewage and taken action after the STOMP tip-off.
The STOMPer said:
"After STOMP published the photo, NEA has identified the sewage leakage to be from a petrol station upstream.
"The water is much clearer and no long smells pungent.
"Kallang River links up with this canal.
"Continue to protect our water this way."

So there was actually a source of pollution leaking into the canal after all.
This incident clearly illustrates just how the carelessness or thoughtlessness of a single business or individual can have an impact on the environment downstream. Everyone has a stake in preserving the cleanliness and health of our waterways.
