Seasonal Variation of the Physicochemical Properties of Water Samples in Mahanadi Estuary, East Coast of India

The two major sources contributing to marine pollution are natural processes as well as anthropogenic activities. The natural processes include precipitation, erosion, and weathering of crystal material, whereas anthropogenic activities include urbanization, industrialization, mining, agricultural activities, etc. Mahanadi is the biggest river source of Odisha, which joins the Bay of Bengal at Paradip. Paradip Township is an urbanized, well-developed industrial township where various anthropogenic activities are contributing pollution to the water sources. In the present study, an attempt has been made to estimate and monitor the seasonal and spatial variations of physiochemical properties of the Mahanadi estuary at the East Coast of India. The result revealed that there is a remarkable variation in the physiochemical parameters, which are attributed to the runoff water getting discharged to the coastal water sources. It is recommended to that waste water and materials are treated before discharging them to the marine water medium.
