HYDERABAD: Unplanned industrialisation in peripheral areas of the city has taken a toll on the quality of groundwater.
Twenty areas within and outside GHMC limits falling under Medchal-Malkajgiri district have bad quality groundwater, where pollutants exceeded the maximum permissible limit prescribed by World Health Organisation (WHO) for drinking water.
Areas with unplanned industries were worst hit in terms of groundwater quality.
"Rapid increase in population, urbanization and industrialization in Hyderabad resulted in drastic increase in water pollution," said the study published in the latest issue of International Journal for Research in Applied Science and Engineering Technology.
Researchers from Government City College and Annamacharya Institute of Technology and Sciences, Hyderabad, collected groundwater samples before and after monsoon in Medchal, Jeedimetla, Shamirpet, Kapra, Keesara, Ghatkesar, Alwal, Qutubullapur, Dindigul, Balanagar, Kukatpally, Shapur, Fatehnagar, Bowenpally, Uppal, Nagole, Malkajgiri, Begumpet, Lothukunta and Cherlapalli.
Samples collected pre-monsoon from Medchal and Balanagar had more parameters exceeding drinking water quality standards.
"Medchal has major water polluting sources in the form of many industries," stated the study report.
In post-monsoon sample analysis, Medchal and Qutubullapur had parameters exceeding prescribed limits.
