Relationship drought with groundwater quality Abhar plain by using SPI and Schoeller diagrams, Piper and Wilcox

Access to water resources from the perspective of quality and quantity necessary for human life and human activities. The protection of these resources, especially fresh water as one of the most important factors is necessary to protect the health and development of communities. It is obvious that the first step for the conservation and optimal utilization of these resources should have the knowledge and identification of potential sources And by doing continuous monitoring of comprehensive knowledge about a qualitative change them to obtain and provide the context of sustainable development. The results show that frequent and persistent drought in recent years has exacerbated the drop in groundwater level plain And despite the establishment of various industries with its natural pollution and increased use of chemical fertilizers in the desert, with little change in reducing the chemical quality of groundwater resources was made. Results of interpretation are diagrams and charts, represent about 63 percent of agriculturally choice in the category C2S1 and C3S1 are 37 percent of the rest of the class. For industrial use about 82% of cases of type are read and 16% of depositing the samples are considered, only 2% of the remaining balance are examples of the type. About 55% of the water in hard water category and 23% in the category of very hard, and the rest (22%) as moderately hard water are introduced. More than 70 to 80 percent of the water in the well and the rest of the acceptable category and only about 3 percent in mid-fall.
