Dye, dye, must see
Reddish water in a canal in Jurong West is likely to be "organic solvent and dye", water agency PUB said.
Residents living near Jurong West Street 62, near Boon Lay MRT station, had reported the phenomenon around 3pm on Sunday.
PUB officers who inspected the waterway around 3.30pm noticed that the reddish water was flowing out from a covered roadside drain, The Straits Times reported.
Sandbags were immediately placed in the drain to contain the discharge and prevent it from flowing downstream, PUB said.
PUB and the National Environment Agency (NEA), traced the source upstream to a perimeter drain near HDB Block 650B, where reddish stains were found.
"Based on test results, the red discharge is likely to be organic solvent and dye," a PUB spokesman said yesterday. Common uses for organic solvents are in the cleaning, paint and plastics industries.
NEA said the clean-up of the canal was continuing. Lianhe Wanbao reported that the water in the canal was clear by 10am yesterday.
