Investigation of temporal-spatial variations of groundwater resources quality in Borujerd-Dorood Plain

Underground water resources are the largest available water resources available to the earth, and their management and quality control are of great importance. The purpose of this research is to investigate temporal and spatial variations of groundwater quality parameters for drinking and agricultural uses based on Shooler and Wilcox classification in Borujerd-Doroud Plain. In this paper, 55 parameters were used in the years 2001 and 2016 for qualitative parameters such as electrical conductivity, sodium adsorption ratio, acidity, calcium, chlorine, magnesium, sodium and sulfate. Ground maps were used to prepare zoning maps that were better suited for Kriging intrusion detection. The results of this study showed that most of the plain areas in the year 1380 were about 59.78% of the resources in the optimal condition, which improved to 95.79% in 2016. In 2001, more than 74.08% of the area had a good and acceptable quality in agriculture classification, which increased to 85.94% in 2016.
