Physico-chemical parameters are the water quality parameters which include physical and chemical characteristics of water which shows that whether the water quality was good or not good for aquatic life. Physico-chemical characters of River Swat water at Batkhela, District Malakand Khyber Pukhtunkhwa, Pakistan was studied from April to July 2014. The aim of the study was to determine the water quality parameters of River Swat at Batkhela, District Malakand and to know that whether the observed values was normal, above or below the normal range and to know that these values was normal or could produce any toxic effect on both aquatic flora and fauna. The water quality parameters were checked through Aqua Check 5 in 1, water quality test strips for total chlorine, hardness, pH, alkalinity and Total chlorine, made by Hatch Company of the United State of America. Total Dissolved Solids and electrical conductivity was checked through Tintometer Multi-direct Machine. Air and water temperature was determined by common mercury thermometer ranged from 0 to 110 0C and dissolved oxygen was measured through dissolved oxygen meter. During the study months the mean values recorded for the water quality p C, Total dissolved solids 0.49 ppm, Electrical conductivity 104μS/c D v Ox g . The results of the present study reveal that River Swat water at Batkhela, District Malakand has good water quality. The water quality parameters are in normal ranges and the water has no adverse effect on growth, survival and reproduction of both aquatic flora and fauna of River Swat.
