EVALUATION OF SOME QUALITATIVE PROPERTIES LEVELS OF GROUNDWATER IN WELL WATER IN THE WESTERN REGION OF AL-HAWIJA DISTRICT, NORTHERN IRAQ

Abstract

A field and laboratory study was conducted to assess the groundwater quality in some villages west of the city of Hawija from November 1, 2022, to April 1, 2024. Water samples were collected from ten randomly selected wells in the study area over the course of one year, starting from January 2023 to December 2023. The study evaluated some physical and chemical properties as well as the properties of the earth elements. The necessary tests were conducted at the laboratories of the Department of Life Sciences/Education College of Pure Sciences/University of Tikrit, the laboratories of the Kirkuk Environment Department, and the laboratories of the Department of Environmental Engineering/Engineering College/University of Tikrit. The results were as follows: Well number four recorded the highest values for electrical conductivity, total hardness, and magnesium ion in January, reaching 3420 micro siemens\ cm, 1200, and 165 milligrams per liter respectively. Meanwhile, well number one achieved the highest sodium ion concentrations in March, reaching 44 milligrams per liter. The highest sodium adsorption ratio reached 3.08 milliequivalents per liter at well number one, and the highest significant percentage of soluble sodium was 12.72% in the water of well number ten, while well number five recorded the highest hazard ratio for magnesium at 39.82%. As a result of the above, there is a need to increase public awareness of the risks of water pollution and its catastrophic effects, as well as to conduct more comprehensive studies targeting other pollutants in addition to assessing the remaining components of the ecosystem such as soil, plants, and others .
