Ulhas River is highly polluted due to the addition of industrial wastes along Dombivli city located near Mumbai in Maharashtra state in India. Dombivli city has two industrial areas. MIDC Phase 1 and MIDC Phase 2. Industrial wastes from both these phases are added to Ulhas river waters. Hence the area of Ulhas river along Dombivli city to study the load of pollution due to addition of toxic heavy metals in river water was selected for the study. Distribution ratio of heavy metals Hg2+, Cd2+, Pb2+, Cu2+, Co2+, Zn2+, Cr6+, Ni2+ and Fe2+ was studied for each season (Rainy, Winter and Summer) for the years 2012 and 2013. Results revealed that distribution ratio of heavy metals Pb2+, Cu2+, Fe2+, Co2+ and Cr6+ increased in year 2013 as compared to the distribution ratio in year 2012. Distribution ratio of heavy metals Hg2+, Cd2+, Zn2+ and Ni2+ decreased in year 2013 as compared to the distribution ratio in year 2012. Distribution ratios were found to be maximum in Ni2+ in Year 2012 and 2013 and Minimum in Hg2+ in Year 2012 and 2013.
