Water pollution due to residents and pilgrims causing waterborne health related diseases especially AGI (Acute Gastro Enteritis) amongst local population. The river water monitoring was carried and a questioner based survey was used to estimate water-borne and enteric disease incidence amongst the local residents and floating population consisting of pilgrims, tourists etc. 1.75% of local population suffered AGI at Alandi and 1.53% local population suffered due to AGI at Dehu. Various health disorders such as skin itching, ear pain, throat irritation, nausea etc were reported in the pilgrims. Multi-criteria approach is used to evolve composite quality index (CQI). The impact due to occurrence of AGI for various factors calculated using a parameter called as Odd Ratio (OR). It is observed that the odd ratio (OR) has decreased by 28% and 32% in Dehu and by 49% and 63% at Alandi during pilgrimage periods of Ashadi and Kartiki respectively, thereby indicating increased trend of number of people suffering from AGI due to pilgrim activities during pilgrimage period in comparison to non pilgrimage period.
