Micropollutants in Red Hills reservoir

Researchers of the Institute for Ocean Management, Anna University, have found microplastics measuring less than 5 mm in the Red Hills reservoir. The reservoir had an average concentration of 5.9n/m3 microplastics in the water.

The water in the reservoir mainly flows in from the lakes contaminated with garbage and sewage in the neighbourhood. The microplastics found are the variety that is used in packaging meat, sweets and snacks, for plastic cutleries, toys, bottles and parts used in the automobile industry. 

Water from Red Hills reservoir is sent to Kilpauk Water Works for filtration. The Chennai Metrowater Supply and Sewerage Board (CMWSSB) uses sand filters for the removal of chlorine and micropollutants. However, there is no tool to remove the microplastics from the water.
