Groundwater quality assessment for different purposes in Eshtehard district, Tehran, Iran

Eshtehard district is characterized with semiarid climate and due to insufficient surface water resources, groundwater is the main water supply in this region. In order to evaluate the major suitability of water for drinking, domestic use and irrigation, the chemical characteristics of groundwater i...
