PETALING JAYA: Klang Valley residents were saved from another round of unscheduled water disruptions, after state authorities managed to stop two river pollution incidents.
Selangor environment, green technology, science, technology and innovation and consumer affairs committee chairman Hee Loy Sian (pic) said that the Selangor Water Management Authority (LUAS) received two complaints regarding water pollution incidents on Thursday (Oct 22), which had the potential to cause the suspension of the state's water treatment plants, yet again.
“Odour pollution was detected at Sungai Kundang at 10.45am during the 24-hours monitoring of the Ops Statik operation at Sungai Gong, Rawang.
“Preliminary investigation by LUAS found that the odour pollution was from biodiesel, which resulted in more than 10TONs (Threshold odour number) found in the Kundang Jaya Industrial area.
“Further investigation by LUAS and Air Selangor at a suspected premise found the same odour and up to 10 tons of biodiesel at the final release area of the premise, ” he said in a statement on Friday (Oct 23).
Hee said LUAS issued a Letter of Order under Section 121 (1), LUAS Enactment 1999 to the premise involved to immediately stop the effluent discharge and perform cleaning activities.
He noted that LUAS had also activated works to remove the odour pollution by placing 12 bags equivalent to 300kg of activated carbon at the area.
“Samples were taken at three different locations at Sungai Kundang and was sent to the Department of Chemistry Malaysia (JKM) for analysis of the content and further related action, ” he added.
Hee noted that a separate incident of a diesel oil spill was detected at the Putrajaya Lake at 9.35am on Thursday, caused by a leak skid tank at the underground pipeline of the National Cancer Institute (IKN), Putrajaya.
“Investigations found that the diesel oil had flowed into the IKN drain and had entered the lake.
“The Putrajaya Corporation (PPj) has instructed IKN to implement immediate cleaning works to prevent the incident from getting worse, ” he noted.
Hee said several mitigation measures carried out by IKN included the repair of connection pipes, placing oil pad and oil boom on the drainage system and suction of the oil.
It was noted that the incident could have potentially led to the pollution of Sungai Langat and caused disruption at the Bukit Tampoi Water Treatment Plant which is located approximately 10km downstream from the spillway.
“LUAS has requested the cooperation of PPj to place an oil boom at the oil spill area between the Putrajaya Lake to Sungai Langat to prevent further pollution.
Hee noted that continuous monitoring will be carried out by LUAS together with the parties involved.
“Both of the incidents were successfully handled immediately by LUAS, Air Selangor, PPJ and agencies involved.
“No disruption of water treatment plant work, nor disruption of water supply is reported, ” he said.
Hee encouraged the public to report any suspicious activities that could potentially lead to pollution to water resources.
“Preservation and conservation of water resources is our responsibility. We hope for the consideration and cooperation of all parties, ” he noted.
