Abstract :

Digha is one of the seaside resort town and tourist spot in the state of West Bengal, India. The present investigation was carried out to assess sea water quality of Digha Mohana. Water sample was collected on January, 2016. Various physicochemical parameters such as pH, total suspended solid (TSS), Oil and Grease, Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), Lead, Cadmium and Polynuclear Aromatic Hydrocarbons (as PAH) were measured as per standard method. Among all parameters, concentration of pH, TSS, Oil and Grease, COD, BOD and Cadmium were below the limit where as Lead and PAH were above the standard limit. This study revealed that coastal water health at Digha Mohana was at verge of pollution. Proper precautions should be taken by pollution controlling authority to avoid further pollution of Digha Mohana coast and to conserve the marine creatures for maintaining the ecosystem.
