Study on Groundwater Quality Using Geographic Information System (GIS), Case Study: Ardabil, Iran

Abstract

This study involves the analysis of water resources pollution data using Geographic Information System (GIS), which is a subset of the purposes such as: study on the status (situaion) of the aquifer, the natural and man-made effects on aquifer quality, evaluation and investigation of quality monitoring results of Ardabil aquifer, study on quality limitations by comparing the results of analysis of wet and dry seasons from water resources with selected standards. Therefore, samples were collected from76 wells, in this region, for the purpose of the aquifer water quality assessment, identification of changing process of pollution and statistical analysis of quality parameters included NTU, TDS, Nitrates and Chloride. Afterwards, maps for each parameter were produced in the geographic information system (GIS) using scientific methods. Thereupon, situation and condition of water quality was measured by quality mapping index of NSFWQ and was applied for whole the basin. This maps and database, which were created by the software, provide and offer an obvious view of what happened in the study area. As a result, it could be applied for a better management of these water resources and planning to prevent further pollution, by relevant organizations.

Assessment and source identification of heavy metal contamination of groundwater using geospatial technology in Gadilam River basin, Tamil Nadu, India

“…The positions were taken into GIS applications and the attribute was created with spatial data in points. The pH, EC, TDS and selected heavy metal spatial distribution maps were developed using the inverse distance Weighted approach IDW using Arc GIS 10.2 (Suresh et al 2010;Vetrimurugan et al 2017;Redvan and Nasim 2017;Severini et al 2018;Yang et al 2020;Mahapatra et al 2020). Geology map was digitized based on the District resource map (Geological Survey of India).…”

Analysis of Groundwater Quality in Bauchi Metropolis (Nigeria) and interpretation using GIS

“…Strong association (R2 > 0.7) between total dissolved solids and electrical conductivity, as well as anions like Ca2+ and Mg2+, is shown by correlation analysis for both study areas. By comparing the outcomes of the analysis of wet and dry seasons from water resources with chosen standards, Herfeh [27] used GIS to study the status of the aquifer, the effects of nature and human activity on aquifer quality, evaluation and investigation of quality monitoring results of the Ardabil aquifer, as well as quality limitations. To analyze the quality of the aquifer's water, identify any evolving contamination processes, and conduct statistical analyses of the quality indicators NTU, TDS, Nitrates, and Chloride, groundwater samples were taken from 76 wells.…”

Methods of Making of Geoinformational and Analytical System of Groundwater Resources in Kazakhstan

“…The GIS of the groundwater of Thailand is designed to prove the possibility of using groundwater as an alternative source of water supply during periods of drought [42]. Information systems for identifying potential areas of groundwater concentration are created for the territories of Iran [43,44,45]. The maps of the main hydrogeological parameters of shallow aquifers of Laos form the basis of the groundwater geoinformational system [46].…”
