Mayur Shitole

The present study was intended to assess effect of Ganesh idol immersion on quality of the surface water for drinking purpose and to determine principal pollutants of water through Nemerow’s Pollution Index (NPI) in Mahad, Maharashtra, India. For this, water quality data of Mahad before and after Ganesh festival was extracted from publically available database of Maharashtra Pollution Control Board from 2016 to 2018 and analyzed for ten physico-chemical parameters namely pH, Dissolved Oxygen (DO), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Conductivity, Turbidity, TDS, Total Solids, Iron and Zinc. Also analysis of NPI water quality index of Mahad and correlation between water quality parameters was done. Analysis of results showed that for all the time from 2016 to 2018 before (Pre-) and after (Post-) Ganesh festival, dissolved oxygen (DO) was noticed to exceeding the permissible limit prescribed by BIS & ICMR with the NPI value between 1.00-1.40 at all three site except for post-2018 at Mahad Dadli Bridge & Mahad Ram Ghat with NPI value 0.92 & 0.98 respectively. Also Iron (Fe) was found to exceeding permissible limit after (Post-) Ganesh festival for 2016 & 2017 and same for Pre-2017 at all three sites.
