WATER samples taken from a sump near a factory close to Sg Rinching was found to have solvent-like odour, which was similar to the odour pollution traced 16km away at the water intake of the Jenderam Hilir raw water pump station, says a Selangor exco member.
A total of 463 areas experienced water cuts on Aug 31, due to the pollution.
Another incident of odour pollution reported by the Selangor Water Management Authority (LUAS) at 4pm on Friday (Sept 3) caused the shutdown of the Sungai Semenyih Water Treatment Plant, which also caused water disruptions in 463 areas in five regions of the Klang Valley.
According to tourism, environment, green technology and indeginuies affairs committee chairman Hee Loy Sian, water samples from the sump and Jenderam Hilir raw water pump station have been sent to the Chemical Department for analysis.
If the findings point to the factory as the source of the odour pollution detected at the raw water pump station, he said the state would haul the factory owner to court.
“We will not compromise. We will charge the factory owner, chairman or director, not the staff.
“This is very sad. In the span of four days, odour pollution happened twice, and we suspect from the same sump.
“The case will be investigated under the Luas (Amendment) 2020 Bill, whereby the party found guilty of causing water pollution must serve a mandatory jail sentence of not more than three years and pay a fine of between RM200,000 and RM1mil, among others, ” said Hee at a press conference after a site visit to the integrated water supply scheme project in Bandar Mahkota Cheras.
Meanwhile, in a statement, Hee said LUAS was alerted about the odour pollution yesterday by the River Monitoring Station in Kg Sg Buah, and had activated Code Red to kick off the investigation to locate the source of pollution immediately, and shutdown Sungai Semenyih Water Treatment Plant.
“Fourteen bags of activated carbon were placed at two locations along the river, where the water from the sump flows to control any pollution that could lead to Sungai Semenyih.
“The odour could still be detected some 300m from the sump.
“However, hourly water samples taken near Jambatan Ladang Bukit Unggul and Jambatan Kampung Rinching Hilir show no odour pollution,” he said.
Hee also said the Environment Department has issued a notice to the factory to stop operations for two weeks, after traces of volatile organic compounds were found in the air, near the last outlet of the premises, which emitted a similar odour to the Aug 31 odour pollution incident.
