Groundwater Chemistry And Modeling Of Aquifer Depth In Islamabad

Abstract

The present research in the Islamabad region involved the collecting and examination of 37 water samples from borewells for a variety of physical and chemical properties in order to map and evaluate the quality of groundwater for drinking purposes. Alongside this study, aquifer depth modeling was carried out to shed light on possible approaches to obtaining cleaner groundwater supplies. The goal of the project is to help build a sustainable and safe water supply for the people of Islamabad by integrating various approaches. In addition, a Water Quality Index (WQI) was computed using sample percentages classified as Excellent Water (5.41%), Good Water (86.49%), and Poor Water (8.11%) in order to measure overall water quality based on WHO recommendations. Through the use of IDW (Inverse Distance Weighted) interpolation and Geographic Information System (GIS) techniques, the aquifer depth model produced a spatially continuous representation that ranged from 25 feet to 399 feet, exposing notable differences in aquifer depth throughout the research area. In contrast to areas of deeper depths suggestive of restricted groundwater availability, the model highlights areas of shallower depths associated with enhanced groundwater accessibility and recharge potential. These results provide insightful information for the region's resource planning and groundwater management programs.
