Surveying the Geographical Distribution of Aluminium Concentration inGroundwater Resources of Sistan and Baluchistan, Iran

摘要

Providing safe water and protecting the resources from pollution sources have become a major concern for the decision-making centers. It is necessary to prevent degradation of water resources by determining and measuring pollutants and enacting state laws. In this regard and to this end, concentration of aluminum in groundwater in Sistan and Baluchistan was measured and the pollution sources were determined. After acquiring information about the location and status of regional water resources used in Sistan and Baluchistan, 457 samples from different areas were collected in 2015 and pH, TDS and aluminum concentration were measured by graphite furnace atomic absorption spectrometry. In addition, a plot of dispersion of groundwater resources and a profile of these groundwater resources were developed using Geographic Information System (GIS) software. The results showed that average and standard deviation of aluminum concentration were 0.015± .010 mgL-1. Therefore, the groundwater resources met the standards for being used as drinking water supply.
