Water Quality and Seasonal Physico-Chemical Study of Surface Water Bodies of Harsagar Pond in Birkona Village in Bilaspur District

The Physico-Chemical parameters of surface water in Harsagar pond situated in Birkona in Bilaspur Chhattisgarh were studied in the months of May to October 2019 for a period of six month from four different directions such as North, South, West and East. Present work deals with a study of Physico-chemical parameters such as pH, Temperature, Total dissolved Solids, Transparency, Alkalinity, Dissolved Oxygen, Biochemical Oxygen Demand, Nitrate, Phosphate in water samples of Harsagar largest pond in Birkona village. The water quality of the samples was compared with standard values given by World Health Organization (WHO) and United State Salinity Laboratory for drinking and irrigation purposes. The maximum value of pH was recorded as 9.2 at station S-N which is higher than the permissible limits of WHO  and showing basic nature of water in north direction of Harsagar pond and the minimum value of pH was recorded as 7.9 at station S-E. The conductivity of the samples was always above permissible limits (WHO) and ranged between 523.7 to 666.9 µmho/cm in May -June 2019.Total Alkalinity varied between 220 [S-W] to 730 mg/l[S-S].The highest alkalinity value of 730 mg/l was seen at S-N in September 2019..Maximum DO level observed was 8.4 mg/l in September 2019 at S-N and minimum value of 3.4 mg/l was found at S-W in June 2019. The maximum value of BOD observed was 38 mg/l at S-N in May2019 and at S-W in June 2019.The nitrate ion in the investigated samples was found to be in the range from 25.7mg/l at S-E in the month of July to 34.6 mg/l at S-N in the month of June 2019 which were within the permissible limit 45 mg/l given by (WHO). From the results it was found that the some of the water samples sites S-W and S-E are slightly polluted while S-N (north) site of water sample was highly polluted as a result of contamination with agricultural and domestic wastes.
