QUANTITATIVE ASSESSMENT OF WATER SAMPLES FROM DIFFERENT SOURCES OF DISTRICT ATTOCK AND ITS IMPACT ON AGRICULTURE

Abstract

Available water resources are getting depleted and water quality is deteriorating due to rapid increase in population to meet the need of human, industrial and irrigational consumption. The study was conducted to analyze the water quality of district Attock for irrigation. The measurement of water quality parameters were found in the ranges such as pH 7.15-7.97, conductivity 452-1750 μs/cm, total dissolved Solids 357-1225, total hardness 100-490, total alkalinity 240-720, chloride 28-387, sulphate 13-140, nitrate 0.02-0.07, nitrite <0.01, iron <0.01and sodium absorption ratio 0.302-1.691 ppm respectively. Concentration of essential metal ions including Na+, K+, Ca2+and Mg2+ was found to be in range of 55-472, 4-6, 18-148 and 6-46 ppm respectively. Results of present study were compared with World Health Organization and other water quality standards.
