VARIATIONS OF GROUNDWATER QUALITY DURING PUMPING TEST IN JOLACK BASIN.N.IRAQ

Abstract

Abstract The pumping test is done for seven location during (24) hours at Jolack basin to get the groundwater quality and their variation. The quality of water is termed as degree of salinity, PH and major ions. Water analysis shows two kinds of water belongs for same family: 1-CaHCO3 of west recharges area. 2-CaSO4 of east recharges area. The ionic concentration is different more than 10 %( significant change), but no change in water family. All the values of ionic concentration and salinity are below the recommended suggested for human drinking, so these limits are within good water quality for irrigation.
