Increasing raw water supply is one ofthe best methods to prevent ammonia contamination, Infrastructure, Public Amenities and Agriculture committee chairman Zaidy Abdul Talib (PAS-Taman Templer) said yesterday.
He was replying to Eddie Ng (DAP-Balakong), who had asked if the state government would be upgrading the filter at the 11th Mile (Batu 11) Cheras and Bukit Tampoi water treatment plants to mitigate contamination at rivers, caused by high levels of ammonia.
Zaidy said the Mitigation Project 2 was underway and the tunnels were expected to be completed by the end of the year.
Dr Xavier Jayakumar (PKR-Seri Andalas) asked about the cause of ammonia contamination and what actions would be taken against those responsible.
Zaidy replied that there were many factors that could lead to such contamination and it was difficult to pinpoint the culprit.
The Star reported that two Selangor water treatment plants temporarily shut due to high levels of ammonia in the water on Feb 12.
The water treatment plants in Cheras and Bukit Tampoi temporarily ceased operations beginning Feb 7 after water readings recorded a worrying level of ammonia.
Tourism, Environment, Green Technology and Consumer Affairs Committee chairman Elizabeth Wong was reported as saying that the high level of ammonia in the water was due to the water level decrease in rivers and lack of rain in catchment areas over the last few weeks.
