Wastes are brought in from outside Negeri Sembilan - Razali

State Secretary, Datuk Dr Razali Ab Malik said the contaminants were believed to have been dumped in the state by parties from outside Negeri Sembilan.

"The wastes were brought in by lorries and dumped in the area and we are taking measures to prevent them from ending in the river.

''We will conduct cleaning work after samples of the contaminants are taken for analysis by the Chemistry Department,'' he told Bernama when met at the scene, here, today.

Due to the dumping incident, he said the area was closed to the public.

''Previously, three waste dumping cases were also detected in the state. Sungai Anak Air Garam, in Mambau, and Sungai Belihoi, in Mantin, were polluted with oil and chemical wastes, respectively, in December last year while Sungai Batang Nilai, here, was polluted with waste oil in August this year.

Commenting further, he said the state government would continue to monitor the area to prevent the dumping incidents from recurring.

The Ministry of Environment and Water (KASA), in a statement today, announced that a shrubby area on the fringe of the industrial area in Jalan Emas, Nilai Industrial Area, here, had been identified as the main location of the wastes.

The ministry said a number of wastes including organic compounds were found at the site.

Yesterday, Pengurusan Air Selangor Sdn Bhd (Air Selangor), in a statement, said 309,687 consumer accounts in Petaling, Hulu Langat, Kuala Langat and Sepang experienced unscheduled water disruptions after the Sungai Semenyih and Bukit Tampoi water treatment plants (LRA) were shut down due to pollutions.
