Glycerine Dumping Causes Aquatic Life Harm in Sungai Guntong Due to Foam and Potential Oxygen Depletion

The dumping of glycerine waste into a sewage manhole is suspected to be the cause of pollution in Sungai Guntong, leading to foamy water and the death of fish. This contamination originates from the Kamunting Industrial area in Bukit Sentosa, where glycerine waste is reportedly discharged into an Indah Water Konsortium Sdn Bhd (IWK) public sewage manhole. The waste then travels through a nearby drain, causing the water to foam white before it enters Sungai Guntong.
Release of Foamy Water Observed

Authorities received a report regarding the release of foamy water and dead fish into Sungai Guntong. This observation was made at a location approximately 19.9km from the Rantau Panjang water treatment plant. The foamy appearance of the water is a direct visual indicator of the waste material entering the river system.
Glycerine Waste Identified as Suspected Source

Investigations by Lembaga Urus Air Selangor (LUAS), Air Selangor, and the Hulu Selangor District Council pointed to the dumping of glycerine waste materials as the likely cause. The waste was allegedly introduced into an IWK public sewage manhole within the Kamunting Industrial area. This method of disposal bypasses standard waste treatment processes.
Impact on Aquatic Ecosystem

While the direct mechanisms are not detailed, the observed outcome of glycerine dumping includes the death of fish. Glycerine, when released in significant quantities into waterways, can alter water quality parameters. Such alterations can include a reduction in dissolved oxygen levels, which are critical for fish survival, and changes in the physical characteristics of the water, such as increased foaming. IWK has been instructed to undertake cleaning operations at the affected manhole to mitigate further pollution.
