Abstract
In Pakistan, the symbols of water stress are ubiquitous in the form of water resources depletion, water scarcity, quality, depletion of level and contamination. Water is a precious gift of God for all living and non-living things to complete the cycle of ecosystem. This research was conducted to check the trends groundwater level and its quality analysis using long term data of same study area. In this study area, groundwater quality and level data of 421 piezometric wells of 15 years were used to analyze through graphical analysis, from a region in Pakistan. The four major indicators for irrigation as recommended by Punjab Irrigation Department are; pH, EC, RSC and SAR. These parameters were used and appraisal for irrigation to fit or unfit the monitoring sites. The results indicate the significant increasing trend of level as well as quality of water. Average declining of groundwater table is 0.0963 meter per year in study area. As 20% of the groundwater depth is declining per year. Sites unfit ratio is 50% of the total monitoring sites being installed with respect to quality parameters. These trends indicate more water extraction in region that cause adverse effect on quality and level. This research is an excellent recommendation for water experts, to amend new law for operation of water resources and its extraction from groundwater through tubewells. The heavy metal concentration, hazardous waste to soil and sewerage of colonies should be supervised on daily basis.
