Assessment of the Chemical Quality of Water in the Halabja-Sulaimani-Kurdistan Region of Iraq

摘要

A study of water pollution was conducted at Halabja-Sulaimani. Water samples were collected from 5 various locations in a radial manner around and within Halabja town. Water sources included artesian wells, drilled wells and Kahreezes. Before the chlorination and disinfection process, water samples were collected and then physical and chemical analyses were conducted. The field works commenced according to a regular schedule twice per month, starting in June and ending in November 2007. The chemical evaluation of the well waters in the present study based on standards given for drinking water by the World Health Organization guidelines, can be assessed as good-quality; ranging from moderately hard to hard, saturated by oxygen and healthy with regard to biological oxygen demand. An evaluation of general water chemistry indicated spatio-temporal changes between studied well waters. In all investigated sites, cation were dominated by calcium followed by magnesium, sodium and potassium in order of decreasing concentrations.
