SHILLONG: The samples of Lukha river are still being analysed pertaining to the mystery of the river turning blue.
Member Secretary of Meghalaya State Pollution Control Board, JH Nengnong told The Shillong Times that though there are no mining activities, coal mine drainage is still there, which may have been one of the reasons why the Lukha river turned blue besides other reasons.
Moreover, during the rainy reason, the water from the uncovered flooded mines can overflow to the river, the official added.
“However, we are still analysing the samples collected,” he said.
The official added that the samples would have been different at a time when mining was prevalent.
Very recently, the Lukha river turned mysteriously blue though earlier, the people rejoiced on seeing it turning to its normal colour, which did not last long.
