Kerala's groundwater resources face severe contamination risks, studies show

Kerala's groundwater is increasingly at risk due to inadequate sewerage, changing rainfall patterns, dense settlements, and unscientific septic tank construction.

A water quality assessment in Pala detected E. coli bacteria in 67% of samples collected from flood-affected areas along the Meenachil river.

A 2024 study indicated that 7.4% of the state's population relies on poor-quality groundwater, posing continuous health risks.
