Abstract :

Due to the shortage of surface water resources and the increased demand for water, supply of drinking water from underground resources is very important. To use groundwater for drinking, it is important to evaluate the qualitative proportion of these resources and to plan the spatial distribution of quality parameters should be considered in order to manage its location. This article aims to investigate the quality of groundwater for drinking water. For this purpose, 10 rings of the wells were used in this plain for the parameters of TDS, total hardness, chlorine, sodium, calcium, magnesium, bicarbonate and sulfate. These parameters were evaluated based on the Schuler charts and were interpolated using ARC GIS software and analyzed by Kriging geostatistical method and the spatial distribution of the parameters in the plain was investigated. According to the Schuler chart, most of the parameters in most samples are placed on a good and acceptable floor and are suitable for drinking. Also, due to the qualitative changes in the groundhandling maps of Golgi Plain, the distribution of parameters in the plain has no specific pattern and almost groundwater is suitable for the area of the plain for drinking
