Abstract:
The water from surface source provides sustenance to plants, animals, constituents of the habitat for aquatic animals and to meet importance of agricultural and industrial need. The present study was undertaken to evaluate the physicochemical properties of livestock farm oriented wastewater in and around Khanapara, Guwahati, Assam. Five farms were selected and wastewater samples from these livestock farms were analysed to find out bacteriological quality using standard analytical methods. The wastewater samples were collected on a monthly basis for a period of 7 months. In the present study temperature, total alkalinity, sulphate concentration, total suspended solids, total solids, chloride concentration, calcium concentration, turbidity,electrical conductivity and dissolved oxygen were ranged from 18.21°C to 27.87°C, 45.00 mg/L to 50.25 mg/L, 145.99 mg/L to 165.65 mg/L, 840.24 mg/L to 875.40 mg/L, 1700.96 mg/L to 1720.81 mg/L, 148.19 mg/L to 164.53 mg/L, 155.99 mg/L to 175.81 mg/L,936.00 NTU to 943.52 NTU, 10.20 ms/cm to 18.00 ms/cm and 14.30 mg/L to 18.39 mg/L respectively. Out of 140 samples studied, most of the samples were found to have the different physicochemical parameters within the prescribed limits with exceptions such as Total Dissolved Solids (860.71 mg/l), Nitrate (248.98 mg/l), pH (12.20) and Biochemical Oxygen Demand (18.25 mg/l). Significant difference between the samples in different months was observed during the study period. Thus, the present study on farm wastewater sources in and around Khanapara indicated that proper wastewater treatment is required in the livestock farms to prevent surface water pollution.
