Water samples were collected during the pre-monsoon period (October 2019) from the lake (Puzhal Lake), the inlet and outlet of the drinking water treatment plant and analysed for the presence of microplastics (MPs). The surface water collected from the lake harbored 3 to 4 microplastics litre-1 of water. The samples collected from inlet and outlet of the treatment plant also had 3 to 4 microplastics/liter of water.
