Assessment of Coastal Water Quality in Mumbai Using the Water Quality Index (WQI) Approach

Abstract: Coastal areas in rapidly urbanizing regions such as Mumbai are often subjected to pollution, which significantly impacts water quality and the environment. This study examines the water quality of seven prominent coastal sites in Mumbai, India, using the Water Quality Index (WQI) approach. The selected sites include Gateway of India, Girgaon Chowpatty, Haji Ali, Juhu Beach, Nariman Point, Dadar Chowpatty, and Worli Seaface. Several water quality parameters, including Biochemical Oxygen Demand (BOD), Dissolved Oxygen (DO), pH, Fecal Coliform, and Temperature, were measured using data sourced from the Central Pollution Control Board (CPCB). The calculated WQI values for these sites indicate varying levels of water quality, ranging from "Poor" to "Very Poor." The study emphasizes the critical need for improved water management strategies and pollution control measures to safeguard public health and marine life
