Abstract: Water is a renewable natural resource essential for all life sustaining systems on earth. Fresh water becomes a scarce commodity due to its over exploitation and pollution. The causative factors for the pollution of water are industries, agriculture and domestic activities. Further, the industrial growth and consequent pollution let into the freshwater system in the form of sewage are a challenge to this fragile ecosystem. Therefore, keeping in view of the above mentioned factors, the physicochemical parameters of the Buckingham canal were investigated in the present study. The water samples were collected on a monthly basis from the study site from March 2011 to February 2012. The samples thus collected appeared to be brownish/blackish in colour and the odour was found to be with a fishy sewage smell. The mean minimum and maximum water temperature were recorded as 21.1 and 32.5˚C and the atmospheric temperature was 22.5 and 34.7˚C respectively. The average pH of the water samples was found to be a minimum of 7.24 and a maximum 8.36. Electrical conductivity varied from a minimum of 1546.0 to a maximum of 2215.0µmhos/cm. The turbidity values ranged from 150.0 to 258.0NTU and total alkalinity was high in summer (1396mg/L) while the minimum values fell during monsoon (175.0mg/L) and winter (150.0mg/L). Total suspended solids level ranged from a minimum of 280.0 to a maximum of 360.0mg/L. Total dissolved solids level ranged between a minimum of 1422.0 and a maximum of 4250.0mg/L. Total hardness values ranged from 270.0 to 1265.0mg/L respectively. The mean dissolved oxygen value of the water samples ranged from 3.5 to 5.9mg/L. For biological oxygen demand, the values ranged from 146.0 to 511.0mg/L, and for chemical oxygen demand it varied between 640.0 and 1572.0mg/L. Changes in the water quality affect the biotic community of the aquatic ecosystem which ultimately reduces the primary productivity thus affecting the entire aquatic ecosystem.
