Coastal Aquifers In Bangladesh Showing "Alarming" Rise In Salinity
Salinity intrusion into the aquifers of the country’s coastal districts has reached an alarming proportion due to unplanned use of groundwater in agriculture and seawater seeping into underground due to sea-level rise caused by global warming.
“We’ve assessed the quality and quantity data of groundwater up to 1,100 feet deep in 19 costal districts. But, we’ve found saline water in aquifers within just 600-700 feet deep,” deputy director (Groundwater Hydrology) at Bangladesh Water Development Board Dr Anwar Zahid told UNB.
He said salinity intrusion has gripped some coastal districts since there is no freshwater layer up to the depth of 1,100 feet.
“There’s no freshwater layer up to 1,100 feet deep in Barguna, Pirojpur, Gopalganj and Satkhira…freshwater may be found 1,300-1,400 feet deep the ground.” The hydrologist said water layer is found up to only 300 feet deep the aquifer in Satkhira, but the layer is full of saline water.
