Assessment of Groundwater Quality Using Geospatial and Modelling Tools

Abstract

Groundwater originates from porous layer. Groundwater resources are one of the most important sources of water for domestic, agriculture and Industrial use in areas with limited surface water resources. The quality of groundwater now faces deterioration as a result of human and natural activities. Assessing groundwater quality is essential to ensure it is safe and sustainable practices. The development of human beings and natural process has led to a significant declination of water quality. Geospatial technology plays a key role in checking and managing groundwater quality. This study presents an integrated approach to assess groundwater quality missing geospatial and modelling tools, aims to identify spatial distribution and potential contamination zone. Geographic Information System (GIS) is used to read map and analyses water quality parameters such as pH, Total Dissolved Solids (TDS), Electrical Conductivity (EC), nitrate, chloride and heavy metal. Inverse Distance Weighting (IDW) is used to visualize the variables of spatial of groundwater quality. The combination of Geographic Information System (GIS) with quantitative statistical and modelling tools enabled at a very high resolution in an efficient grounded methodology. This approach proves to be sustainable groundwater management, groundwater management, environmental protection and public health safety. Overall this study highlights the importance of continuous monitoring and the application of advanced tool to safeguard vital groundwater resources.
