Kerala’s water bodies which have been heavily contaminated due to dumping of various kinds of waste were cleansed during the flooding events which hit the state in 2018. It had a positive effect on the surface water quality in the water bodies, says a study conducted by the researchers of Kochi-headquartered Central marine fisheries research institute (CMFRI).
The devastating floods led to increased freshwater flow into the estuaries. The surface waters were sampled from ecosystems, viz. lower end of estuaries, intertidal waters of beaches, mudbank region and inshore waters, from some districts in the state.
