Summary: | Background: Unsustainable development of human societies, especially in arid and semi-arid areas, is
one of the most important environmental hazards that require preservation of groundwater resources,
and permanent study of qualitative and quantitative changes through sampling. Accordingly, this
research attempts to assess and analyze the spatial variation of quantitative and qualitative indicators of
Orzooiyeh groundwater resources in the Kerman province by using the geographic information system
(GIS).
Methods: This study attempts to survey the spatial analysis of these indexes using GIS techniques
besides the evaluation of the groundwater resources quality in the study area. For this purpose, data
quality indicators and statistics such as electrical conductivity, pH, sulphate, residual total dissolved
solids (TDS), sodium, calcium; magnesium and chlorine of 28 selected wells sampled by the Kerman
regional water organization were used.
Results: A comparison of the present research results with standard of Industrial Research of Iran and
also the World Health Organization (WHO) shows that, among the measured indices, the electrical
conductivity and TDS in the chosen samples are higher than the national standard of Iran and of the
WHO but other indices are more favourable.
Conclusion: Results showed that the electrical conductivity index of 64.3% of the samples have an
optimal level, 71.4% have the limit of Iran national standard and only 3.6% of them have the WHO
standard. The TDS index, too, did not reach national standards in any of the samples and in 82.1% of
the samples this index was on the national standard limit. As per this index, only 32.1% of the samples
were in the WHO standards. |
