Population explosion, urbanization, industrialization and human apathy have all contributed towards increasing quantities of pollutants leading to an “ecological disaster”. Pollution of water has emerged as one of the most significant environmental problem. About 60% of the untreated sewage gets into the Buckingham canal and the Adayar river takes the rest. Hence, the present study investigates the nutrients of Buckingham canal water from March 2011 to February 2012. The quantity of nutrients present in the Buckingham canal water samples varied widely. Free ammonia concentration ranged from 1.24 ±0.02 to 1.81 ±0.53mg/L. The nitrate and nitrite ranged from 40.75 ±1.06 to 80.65 ±4.25mg/L and 11.8 ±0.11 to 13.9 ±0.05mg/L respectively. Chloride content ranged from a minimum of 380 ±0.50 to a maximum of 1325 ±1.01mg/L and the fluoride content from 0.51 ±0.02 to 1.54 ±0.03mg/L. Potassium content in the water samples ranged from 38 ±3.51 to 88 ±4.72mg/L. The maximum calcium content in the water sample was 282 ±1.97 mg/L while the minimum ranged from 60 ±0.93 to 92 ±0.81mg/L. The magnesium values were also observed to be at a maximum of 150 ±0.16 and a minimum of 112 ±2.0mg/L. The silica content varied from 37.56 ±0.06 to 63.65 ±0.09mg/L. The phosphate content varied from 15.23 ±0.02 to 18.66 ±0.04mg/L. Sodium concentration was estimated as a minimum of 286 ±2.48 and a maximum of 453 ±8.15 mg/L and sulphate in water samples varied between 143.05 ±3.05 and 162.73 ±6.23mg/L. Presence of nutrients and oxygen is essential for the sustained proliferation of organisms. However, nutrients lead to undesirable change in the structure and function of ecosystems. Nutrients stimulate growth of aquatic plants which in turn decay and consume oxygen and emanate hydrogen sulphate. This accumulation exerts high biological demand on the ecosystem. In addition, with accumulation of nutrients, the organic biomass increases leading to pollution.
