At least two rivers in eastern Meghalaya have turned
blue again apparently due to “high acid content”, resulting in death of
scores of fishes.
The Lukha river in East Jaintia
Hills district and certain sections of the Myntdu river in West Jaintia
Hills district have changed their colour to a bright sky blue indicating
a very high acid content.
“We have observed that the Lukha has slowly
changed its colour in the past few days after the monsoon rainfall
subsided.
The colouration has worsened and the whole river has turned
into bright sky blue,” Sonapyrdi headman J S Lamare told
Although the colouration was first detected way back in 2007, no one
has been able to find out the reason for the colouration, leaving
scientists and environmentalists baffled.
The Meghalaya State Pollution
Control Board (MSPCB) in its 2012 report blamed acid effluents from coal
mines as the major probable causes of water pollution in the area.
