The seacoast of Khar Danda 18.96°N and 72.82°E is to the western edge of Mumbai shore of Bandra Suburb at an altitude of 10m to 15m. It has a tropical climate and temperature varying from min 18°C to max 37°C. The sea line is marked by black Deccan basalt sea rocks. It receives torrential Indian Ocean monsoon rains, between June and September. The Khar-Danda fishing village in the south is the oldest area where Koli community resides to the north is the Carter road Promenade. Human activities like domestic, agricultural or industrial have an impact on water and the ecosystems. Fish farming is the important occupation and several other anthropogenic activities like cremation of dead bodies, domestic sewage, and fecal discharge has tremendously affected the ecosystem of the shore as well as the sea. About 11,494 industries are located in the city and 24,554 industries are located in suburbs, contributing as the major source of industrial pollutants. Nearly half of the Mumbai’s populations about 42% of residents are slum dwellers or homeless lacking sewage and sanitation facilities. They use coastal areas as a natural toilet which results in a huge amount of sewage released directly into the sea. A massive amount of these wastes enter the coastal water in and around Khar Danda which is under the grip of pollution. These pollutants carry soil and particles laden with carbon, nitrogen, phosphorus, and minerals. This nutrient-rich water can cause fleshy algae and phytoplankton to thrive in coastal areas; known as algal blooms, which have the potential to create hypoxic conditions by using all available oxygen. Moreover, a drastic depletion in faunal and floral diversity of the area has been observed causing destruction of mangroves as well as a decline in fishery catches. The Pomfret catch has declined from 24,000 tons in 1982 to 3,000 tons in 2006-07. Also, the Bombay duck catch has crashed from 80,000 tons in 1982 to 23,000 in 2006 (Times of India by S.S.Singh.2010). The Physio-chemical parameters like temperature, pH, Hardness, D.O, B.O.D, CO2 , Nitrate, Nitrite, fecal coliform(FC) and total coliform (TC) studied are presented as a minimum, maximum and mean values to assess the extent of water quality variation throughout the year from OCT. 2017 to SEPT. 2018.The result indicated that parameters were found to be greatly affected.
