GUWAHATI, December 7, 2017: After the controversial case of Arunacahal’s Siang river turning muddy allegedly due to the Chinese project of cave construction under the mentioned river, it has come to light that even the water of Brahmaputra river has changed its color and has become muddy in Assam.
Himanta Biswa Sarma, Health Minister, Assam suspects that it may be due to the construction of dam or some accident in China that has caused Brahmaputra’s water having abnormal deviation like containing cement particles and turning muddy.
“Brahmaputra has suddenly become muddy. So we have tested few samples in Tezpur (District Level Laboratory of the Tezpur Division of the Public Health Engineering Department). The sample shows the water containing a lot of mineral properties.
District Level Laboratory of the Tezpur Division of the Public Health Engineering Department informed “Brahmaputra has suddenly become muddy. So we have tested few samples in Tezpur and the sample show the water containing a lot of mineral properties”.
In a meeting Sarma told the reporters “And people are also saying there is a lot of cement which has now mixed with the water,”
The river enters India after flowing through the Tibetan plateau as Yarlung Tsangpo. It flows through Arunachal Pradesh for about 230 km as Siang river to reach Pasighat and then joins the Lohit and the Dibang to form the Brahmaputra river in Assam.
The Brahmaputra’s water turning muddy and change in the colour for over a week now in the winter season has caused concern among people and authorities in the state.
Assam Pollution Control Board Member Secretary B K Barua said samples of the water of Brahmaputra is “abnormally turbid” and samples have been collected in Guwahati, Dibrugarh and Tezpur for drawing a definitive conclusion after tests.
Meanwhile, the State Water Resources Department has decided to send letters to the Union Ministry of Water Resources (MoWR) to take up the Siang/Brahmaputra-related matters with the Chinese government along with hydrometeorological data of the major rivers of Assam.
The water of the Siang river in Arunachal Pradesh, which has turned dark and muddy, has become unfit for human consumption, the State Water Quality Testing Laboratory (SWQTL) has said in a report.
The report stated that the Nephelometric Turbidity Unit (NTU) content of the water sample was 482, while the iron content was recorded at 1.65 mg/litre, which was beyond the permissible limits.
