Investigating potential risks of quantitative and qualitative impacts on drinking water sources Villages inJajroud basin in GIS system

The growing trend of development and various human activities leads to the entry of various pollutants into groundwater. The desirable physical and chemical quality of water is critical to the consumer, consumer health and maintenance of the water supply system. Currently, one of the problems of underground water sources is the pollution of drinking wells and other underground resources to urban and industrial wastewater, which leads to a change in the water quality of these resources and makes it impossible for them to drink. This study investigated and zoned elements Different qualitative water flows within the city of Jajroud Basin's city by Arc GIS software. For this purpose, water quality parameters were sampled from all the sources used in drinking water in this area. Then all the information was entered into the software environment under descriptive layers and to produce qualitative zoning maps. These maps show a significant trend for most parameters, due to the widespread use of water and the probability of the outbreak of various diseases Concerned about drinking in this area, this research could pave the way for future decisions on correct water harvesting in the study area.
