Abstract

An assessment of the water quality of surface and ground water was studied in three different seasons namely summer, premonsoon and winter. Choudwar industrial area i.e Ferro-alloys Unit (IMFA) and its Captive Thermal Power Plant, Air Force Defence Unit (Aviation Research Centre, Government of India) and one major industry i.e. Arati Steel at Ghantikhal towards the west on the bank of river Mahanadi. Four parameters namely pH, Dissolved Oxygen, Biochemical Oxygen Demand and Fecal Coliform was considered to compute Water Quality Index based on National Sanitation Foundation studies. Our findings highlighting the overall quality of ground water and surface water adjoining the study area except Putoloi (of Birupa) River which remains unaffected in spite of the discharge of effluent water of industrial units located in the study area. However there is deterioration of water quality of few stations due to industrialisation and human activities.

Keywords

Choudwar Area, NSF Water Quality Index, Dissolved Oxygen, Biochemical Oxygen Demand, Fecal Coliform.

Abstract

The main objective of this paper is to examine pollution threat, especially to the groundwater resources, around Paradip industrial area located on the Bay of Bengal Coast in Port city of Orissa, India and suggest remedial measures that may also be relevant to other industrial areas on the Indian Sea Coast. Twenty two samples were collected from various sources, such as dugwells, borewells, dug-cum-borewells for chemical analyses. These analyses show that the area in general is characterized by hard water and slightly salinity hazard, possibly due to its proximity and hydraulic connection with the sea. Although the potability of groundwater is questionable in certain pockets, it is good enough for irrigation purposes at present. Low pH value and high organic pollutant contents in the adjoining Atharbanki creek and Taldanda canal water is a matter of great concern and may be attributed to the indiscriminate disposal of industrial effluents to the drainage channels connecting the creek. Ground water quality varies widely, even at short distances, depending on hydrogeological conditions, pumping period, depth of aquifer, type of soil, and human activities. The degradation of groundwater quality is mainly due to the pollution caused by the rural use of land, as well as its intensive exploitation. The salination and toxicity are potential problems of groundwater quality, especially in some areas, indicating that there is a need to take direct actions for the purpose of the optimum management of water resources in the Region of Paradip.

Keywords
