AbstractThe physico - chemical parameters of a freshwater pond (Sulur pond) in Coimbatore district, South India was studied from January 2004 to April 2004 at two zones namely middle zone and sewage mixing zone during 30 days interval. The freshwater pond was used for drinking and cultivation purposes for many years. At present the pond was a dumping area for the domestic and industrial effluents.Hence an attempt was made to study the water quality parameters of the pond and its suitability for drinking and cultivation purposes. During the study period all the water quality parameters like temperature ( 29.0 to 35.0 C), pH (7.5 to 7.8), dissolved oxygen (0.8 to 1.6 mg/l), COD (3.2 to 4.8 mg/l), total hardness (400 to 450 mg/l), dissolved carbon dioxide (5.5 to7.5 mg/l), chloride (415 to 450 mg/l), phosphate (0.001 to 0.017 mg/l), carbonates ( 0.001 to 0.0015 mg/l),bicarbonates (0.06 to 0.09 mg/l)and salinity( 0.18 to 2.21 ppt) were above the ISI level. The alterations of the water quality parameters of the pond indicate the pollution load of the pond and the water is unsuitable for drinking and cultivation purposes. The probable reasons for the alterations of the water parameters were discussed with the source of the pollution and their influence on water quality parameters.
