KUALA LUMPUR: Most rivers in Selangor which are the main sources of water supply in the state have been found to be polluted and could potentially become a serious threat to the availability of this basic necessity.

Universiti Putra Malaysia Environmental Forensics Research Centre unit head Dr Hafizan Juahir said the clean water sections of the rivers were getting shorter due to development, especially for housing.

For example, he said, the length of Sungai Langat, the leading source of raw water in the state, was 149.3km -long but the clean water section had been reduced to only 49.3km while the remaining were polluted.

“The entire length of Sungai Langat has entered the Class 3 and 4 categories of being polluted and if the quality worsens, it can be considered a dead river,” he said.
