SEREMBAN: A stretch of Sungai Simin has turned cobalt blue and fingers are pointing at a factory nearby.
State Department of Environment director Norhazni Mat Sari said its investigations revealed that the bluish water came from the plastic recycling factory.
“We instructed the operator to pump out the bluish water and clean up the stream immediately and we have been monitoring it ever since,” she said.
Pictures and a video clip of a “blue” stream had gone viral since Monday and many netizens have voiced their displeasure over the irresponsible act.
The department immediately dispatched a team to the Senawang Light Industrial Park where the factory was located following a public complaint made to the department’s headquarters in Putrajaya on Monday.
Norhazni said the operator has been cooperative.
Her team was satisfied with the clean-up operation along an 8km stretch of the stream by the operator.
“We have also issued a stop-work order to the factory until our investigations are completed,” she said.
Asked if the bluish fluid was hazardous, she said samples had been sent to the Chemistry Department for analysis, but it could not be immediately established if the bluish fluid was a type of dye, ink or other chemical, she said.
Despite the bluish colour, the pH reading of the water was normal (seven) and the department did not detect any dead fish in the stream.
“We were told that the recycled items they were washing were contaminated and that was how the bluish effluent got into the stream,” she said.
The case is being investigated under the Environmental Quality Act 1974 and the department will take action once it receives the analysis of the samples.
