Abstract
Mumbaiâs reliance on the Arabian Sea for various activities, such as fishing, transportation, and recreational purposes, makes it essential to consistently monitor seawater quality. This proactive approach is crucial not only for safeguarding the health and well-being of its residents but also for protecting marine biodiversity and supporting sustainable economic growth. Regular assessments can help detect pollution levels, prevent potential health hazards, and maintain the ecological balance of the coastal environment. This study investigates the variations in sea water quality off the coast of Mumbai by comparing parameters from two distinct periods: pre-monsoon (March to May 2023) and monsoon (July to September 2023). Sea water samples were collected from key locations including Colaba, Worli, and Versova respectively. The samples collected were further analyzed for a range of qualitative and quantitative parameters: pH, electrical conductivity (EC), total dissolved solids (TDS), salinity, temperature, turbidity, dissolved oxygen and biochemical oxygen demand (BOD). The analysis revealed a significant increase in BOD levels post-monsoon, highlighting potential impacts of sewage discharge and other anthropogenic factors. Despite these changes, the pH levels remained relatively stable, ranging between 7.6 and 9. These findings underscore the influence of seasonal variations and urban activities on seawater quality, emphasizing the need for continuous monitoring to safeguard Mumbaiâs marine environment and public health.
