Sustainable development analyses to evaluate groundwater quality and quantity management

摘要

In this study, a qualitative and quantitative change of groundwater resources of Damghan Basin was analyzed. Fifty-four active piezometric wells was used in the region which mostly suffer from shortage of drinkable water standard. Physical propertiesof 59 quality wells have been evaluated in order to determine the quality of groundwater by measuring factors such as pH, hardness, chloride content, electrical conductivity and total dissolved solid (TDS). By physical/chemical analyses, it was concludedthat results for selected resources of Damghan Basin have been more comprehensive during 2008-2009 in comparison with other periods because scattered data cover all areas of the basin. By comparing the results with drinking water quality standards (WHO), assessment of water resources were conducted as acceptable to unsuitable. Hydrochemical perspective drawn using Piper diagram indicates that most of the selected water resources in the area contain chloride constituents. However, Na% values indicate that just 83 % of samples are permissible for using in irrigation purposes.
