Abstract

One of the serious challenges in ensuring and promoting community health is gradual increase in contamination levels of drinking water of communities across the world. The purposes of this study were (1) to evaluate the chemical quality of groundwater in the Bandar-e Gaz city and (2) to determine spatial distribution of groundwater quality parameters (total hardness (TH), chloride, nitrate and fluoride concentrations, and (3) mapping the quality of groundwater using Geographical Information System (GIS) software. In this study 20 groundwater samples were collected from 5 wells in two successive 2010–2011, in the rainy and dry seasons. Sample preparation and analysis, according to standard methods were done. Based on the findings of this study, it can be expressed that the average concentration chloride and nitrate parameters in Bandar-e Gaz drinking water is within the 1053 standard limit in Iran, except fluoride content is lower than the standard and hardness was high in majority of water sample groundwater. According to the zoning maps of groundwater, in the dry season’s nitrate and hardness concentration is greater than rainy seasonal. The data showed falling and rising trend in CL concentrations, respectively. This study indicated that all parameter within the standard except fluoride then, its necessity to addition fluoride in that’s regions population food chain and drinking water. Management of the utilization and protection greed underground waters should be as a basic principle in the planning Bandar-e Gaz city. © 2017 Desalination Publications. All rights reserved.
