Abstract
A systematic study was conducted to ascertain the hydrochemistry of ground waters in southwestern part of Punjab, in relation to their suitability for irrigation and evaluate their effect on crop growth and chemical properties of soils. The ground water samples from running tubewells were collected and analysed for various chemical constituents. Based on their major cation and anion content, five hydrochemical facies have been identified and mapped. Majority of ground waters occur as Ne-S02,--C1- HC0-3. The composition generally changes from HCO-3-C1- SO2-4 to C1-S02-4-HCO-3 and S02-4-C1--HCO-, as we move form high to low rainfall areas.
