EDWARD RAJENDRA , ALLISON LAI and NOEL FOO at the Selangor State Assembly
SIXTEEN cases of river pollution were recorded in Selangor until the end of October, with eight in Sungai Langat forcing the Langat water treatment plant to shut and affecting more than a million customers in Hulu Langat, Kuala Langat, Petaling Jaya and Sepang.
“Sungai Langat alone was polluted eight times. On four occasions, it was caused due to ammonia pollution because the water level in the river was at its lowest.
“Because of high ammonia levels, the water treatment plant had to be closed for a thorough clean-up,” Tourism, Environment, Green Technology and Consumer Affairs committee chairman Elizabeth Wong told the state assembly.
She added that there were two incidents in September and another two in October due to river pollution in Sungai Semantan, Pahang.
“In four cases, the pollution originated from unlicensed factories along Sungai Lalang.
“Two other case originated in Nilai, Negri Sembilan,” she said in reply to Datuk Johan Aziz (BN-Semenyih).
Wong did not name the factories involved in the river contamination.
“The recent palm oil spillage near the Labu water treatment plant in Negri Sembilan did not cause a total closure of the plant.
“The treatment plant was closed in stages to facilitate the Off River System cleaning method where water was still channelled while cleaning was being carried out.
On the Labu pollution case, the state has initiated investigations into the matter and will hand the investigation papers soon to the Attorney-General’s Office for further action,” she said.
She added that Sungai Semenyih Water Treatment Plant had to be closed eight times from Sept 22 to 24 and three times from Oct 23 to 28.
Operations at the Langat and Cheras Mile 11 treatment plants were also affected on Oct 7 and 8.
