Abstract: The study covers about 65 km of the river starting from Kushawart Trimbakeswar to Saikheda Village, from where it enters the city. Ten locations were selected for collection of water samples from the river and the samples were analyzed for water quality parameters in the Environmental Laboratory of the Maharashtra Pollution Control Board (MPCB), Nasik. These data as well as data from the Central Pollution Control Board (CPCB) were used to compute the National Sanitation Foundation Water Quality Index (NSFWQI), mostly applicable in the USA and India. s. These all activities resulted in degradation of water quality. These all problems are largely concentrated in and around urban areas. Keeping this view in the account systematic study has been carried out the water quality of Godavari river in Nashik city. The overall values showed good water quality status (WQI 133.44) at upper stream in the study area, but as it enters in urban area water quality becomes deteriorate (WQI 35.01). The feld observations reveal that water quality is declining due to many human activities mainly industrial, domestic and religious waste. To analyze the water quality index (WQI) is the main aim of the research with remedial measures to mitigate the deterioration and related consequences in future.
