GUA MUSANG (Bernama): The Chemistry Department has denied a non-governmental organisation's claim that it took samples from another river and not from Sungai Lebir, the river that the Bateq Orang Asli in Kampung Kuala Koh used as their water source.

Department chemist Dr Mohamad Rafiq Sulaiman said the samples were taken by the Environmental Department from six locations in the settlement based on the direction of the Orang Asli Development Department.
