Brahmaputra water turning black: reason may be earthquake in Tibet

A preliminary study has found that the water of the Siang river, which originates in southern Tibet and becomes the Brahmaputra upon entering Assam through Arunachal Pradesh, is turning black due to a recent earthquake in the region, Union minister Arjun Ram Meghwal has said.

"We have been getting reports of pollution in the river and its water turning black. The Central Water Commission (CWC) has started looking into the matter recently and people have been sent to the internal areas," the Union minister of state for water resources said in New Delhi on Sunday.

He added that according to the preliminary findings, the path of the river was temporarily obstructed after an earthquake in Tibet on November 17.

"There is a strong possibility that the colour (of the river's water) has changed due to natural reasons," the minister said.

Congress MP Ninong Ering, representing the Arunachal East constituency in Parliament, had recently written a letter to Prime Minister Narendra Modi in this regard, noting that the water of the river changing its colour was an unusual phenomenon in the winter months.
