ABSTRACT

Groundwater is imperative for the continuance of life and sustainability of ecosystem. Contamination of the water is the well-recognized danger to the public health in Pakistan. Hence, this study was conducted to assess and map the spatial variation of groundwater quality in the surroundings of Dijkot Branch Drain by using the Geographical Information System(GIS). For this purpose, sixty samples of groundwater, ten samples of wastewater and five samples of sludge were collected along with their coordinates from the study area. The collected samples were analyzed for chemical parameters and heavy metals, such as pH, EC, TDS, Carbonates, Bicarbonates, Arsenic, Lead, Chromium, Cadmium, Zinc. The results obtained from the study were compared with WHO guidelines. Then, the values of these water quality parameters were mapped by using GIS software. Arc GIS V 10.2 was used for raster interpolation. To exhibit the spatial variation of groundwater quality scenario of the study area, Kriging method was adopted. on. It was generally observed that none of the parameters in the wastewater samples was found to be within the permissible limit. The research study resulted that the groundwater of the study area is deteriorated by Dijkot Branch Drain and is not fit for drinking purpose.
