ABSTRACT

Water is one of the most important components of our environmental resources, for all living organisms. Survival of human and socio-economic development depends largely on the availability and use of water in agriculture industry. The evolution of irrigated agriculture in large alluvial basin traces the interaction of human society with nature. To begin with, water was needed largely for irrigating crops; public health, industry and recreation claimed a very small percentage of the total water supply. The water needs increased with time to meet the requirement of more food and industries with increasing population. Ground water (GW) resources

meet the increasing demand of water for domestic and industrial purposes. Water pollution is a phenomenon characterized by deterioration of the quality as a result of various human activities. The poor quality of drinking water in our country is more due to contamination than due to inferiority of the sources. It has been estimated that about 25% of the irrigated land of world is affected to some degree by water salinity.
