State tourism, environment and green technology, and orang asli Affairs Committee chairman Hee Loy Sian, said in the first incident, odour pollution of up to 10 TON (threshold odour number) was detected in Sungai Kundang at 10.45am yesterday during the 24-hour Ops Statik Sungai Gong Rawang.
He said an initial investigation by Lembaga Urus Air Selangor (LUAS) found that the odour pollution was caused by biodiesel substance of over 10 TON from the Kundang Jaya industrial area.
“Further investigations by LUAS and Air Selangor Sdn Bhd into nearby premises found the same odour pollution of up to 10 TON in its final discharge.”
Hee said LUAS placed 200kg of activated carbon to control the pollution in the area, and samples of the effluent had been sent to the Chemistry Department for analysis.
In the second incident, diesel spill in Putrajaya Lake was detected at 9.35am, believed to have been caused by a leak in the underground tank at the National Cancer Institute.
Putrajaya Corporation had instructed the institute to carry out immediate cleaning work to prevent the situation from getting worse.
“The incident has the potential to pollute Sungai Langat and cause the Bukit Tampoi WTP to shut down.
“Close monitoring is being carried out by LUAS and all relevant parties,” Hee said.
