GUWAHATI:The change in the colour and quality of the Brahmaputra water is attributed to an earthquake that rocked Tibet where the mighty river originates before owing across Arunachal Pradesh and Assam before ending in the Bay of Bengal through Bangladesh.
Experts maintain that the earthquake of moderate intensity might have blocked a huge passage with mud and soil which the river water is sweeping away during the last couple of days.
Water samples are being collected in different locations across the state to be sent to the laboratories for further confirmation.
But the authority has suggested the people not to use the river water which might strike health hazards.
For the third consecutive days the fisherman in Jonai, Tezpur, Guwahati, Goalpara and Dhubri have stopping fishing on the river. But the water colour and quality have refused to improve.
