Abstract
The study aims to evaluate the quality of groundwater of wells spread in Salah al-Din Governorate/Tuz Khurmatu for drinking, irrigation, livestock and poultry purposes. The study area is located between latitudes (34º 53-59=-34º 52-46=) north and longitudes (44º 44-32=-44º 36-41=) east with a total area of (191801.65) hectares. 25 wells were randomly selected in the study area during the dry season (September 2024) and the wet season (March 2025). After that, water samples were taken to the laboratory to conduct physical and chemical analyses. There are three types of WQI for drinking water in the dry season. The first type is excellent for drinking, and it reached 16% of the total wells. The second type is good for drinking, and it reached 44%. The third type is poor and not suitable for drinking, and it occupied 40%. As for the wet season, the results were different, and it was found that there were three classes for different purposes was evaluated and compared. Through a detailed study of the variation in groundwater characteristics in different areas in Tuz Khurmatu district by determining the irrigation water quality index with eight criteria, the drinking water quality index with twelve criteria, and the water quality index for livestock and poultry with eight criteria, it was found that the wells of the study area with respect to For the indicators of water quality for drinking, irrigation, livestock and poultry in the dry season, the categories were (excellent, good and poor), (excellent, good, poor and very poor), (excellent, good and poor) for each of them respectively. In the wet season, the water quality for drinking, irrigation, livestock and poultry was (excellent, good and poor), (excellent, good and poor), (excellent, good and poor).
