Surface Water Quality Assessment of Godavari River by WQI and Arc-GIS. Surface Water quality status of Godavari River under Nanded District- Maharashtra, India by using water quality Indexing

      Аннотация: Surface water ecosystems are complex with interlinked physical, chemical and biological systems. Day to day activities of Human causes changes in these attributes thus affecting the aquatic living resources over time. In the case of fresh water resources, municipal sewage, agricultural run-off and industrial effluents gets discharged into streams, lakes and rivers thereby making these water resources unsuitable for drinking purpose. Since water is a universal solvent, most of the pollutants get dissolved easily which degrades the overall surface water quality. Therefore, it is necessary to conduct periodic monitoring of water resource. It not only helps in recording the levels of various pollutants in water bodies but also help policymakers; government bodies to formulate policies that can help protect the human health and the environment.
