Abstract

This study had been conducted in the College of Environment – Mosul University and the College of Education – Tikrit University which included a field survey to estimate some physical and chemical characteristics of water. Also, it is used to estimate some heavy metals. The field survey started on April 2008 till March 2009 where four sites of wells’ water were chosen within Al-Mahalabia area. Water samples were taken from these sites monthly to identify some its physical characteristics such as (water temperature and electrical conductivity ) and some chemical characteristics (pH, dissolved oxygen, biological oxygen demand, BOD5, total alkalinity, calcium and magnesium hardness, nitrate, phosphate, chlorides ). The results referred to an increase of EC and TH. for all studied sites, Also, the results indicated that pH values were inclining to alkalinity in all studied sites, and these metals’ values increased significantly in wells’ water sites.
