PETALING JAYA: Perbadanan Urus Air Selangor Bhd (PUAS) has reported to the Department of Environment (DOE) that the water supply to several residential areas on Tuesday had an offensive smell.
Its general manager (operations), V. Subramaniam, said that initial samples sent to a private laboratory revealed that industrial chemical waste were being discharged into a tributary of Sungai Semenyih on Monday.
However, he declined to reveal more, saying PUAS was awaiting the results of the DOE probe.
“The DOE is in charge of the environment and we will have to wait for their results before we can comment (further) on the water quality,” he said.
Subramaniam said affected residents, mostly those staying in Puchong, Putrajaya and Subang Jaya, had complained that the water smelled of solvent.
However, PUAS has assured consumers that the water was safe for consumption, saying it had passed the tests conducted by the Semenyih water treatment plant.
Subramaniam said even the plant operator had complained on Tuesday about a ''chemical-like'' smell in the water.
''The plant operator has traced the source to an industrial site in Nilai,” he said.
''We are awaiting the test results before anyone can be called up to explain why they discharged industrial wastes into a tributary of Sungai Semenyih,” he added.
S. Mahesan, a resident of Taman Sentosa, off Jalan Klang Road, said the water supply often had an odour even after being filtered at his apartment home.
“The smell is very strong. The authorities have to do something before dirty water becomes a regular feature,” he said.
