HYDERABAD: If you think only the Hussainsagar lake is polluted, you are mistaken. The groundwater table in the catchment area, that serves the once picturesque but now highly contaminated lake is marred by chemical and industrial pollutants. And Hussainsagar catchment is not a small area. It covers 42% of the total area of GHMC.
A joint research study by teams from the National Geophysical Research Institute (NGRI), Hyderabad, and Telangana state groundwater department has revealed that a larger part of the groundwater table in the catchment of Hussainsagar is contaminated. The pollution levels go up in the summer but the contaminants get diluted during the monsoon.
