"Pasir Gudang chemical spill: Singaporean among three charged over pollution of river", 24 March 2019

Two directors and a lorry driver of a used tyre-processing company were charged in the Sessions Court here with being involved in the chemical dumping into Sungai Kim Kim in Pasir Gudang.

...Meanwhile, Johor police...are hunting for another Singaporean suspect...a businessman, was believed to be one of the owners of a factory which was involved in dumping toxic waste into the river....

...The Malaysian federal government and Johor state officials scrambled for some two weeks to clear chemicals from the river....

Malaysian authorities said last Sunday that the clean-up of the 1.5km polluted stretch of the river was complete, with 1,250 tonnes of soil, water and sludge removed.

The government shut 111 schools in the Pasir Gudang area to prevent more students from falling sick and becoming hospitalised after inhaling fumes from the chemicals. Many residents who live around the river also fled at the height of concerns over toxic gases wafting into their homes.
