تقييم المياه الجوفية في بعض ابار قضاء الدور في محافظة صلاح الدين وسبل استثمارها

Abstract

This study was conducted in the district of Al-Dour, Salah al-Din Governorate, with the aim of determining the qualitative characteristics of groundwater and evaluating its suitability for agricultural uses and ways to invest it. This study relied on the laboratory test results of the Groundwater Division in Salah al-Din, which included (12) wells distributed in different areas of the study area.The study showed a clear variation and difference in all qualitative characteristics, which is due to the difference and diversity of geological formations in the Al-Dour district. We also found that the sodium adsorption values ranged between (0.4-4.7) mg/l, which means that the well water falls within the range of water suitable for irrigation of agricultural crops.The study also showed that the percentage of sodium values indicated that some wells fell within the range of excellent water, while wells 2, 8, and 11 were only within the range of good water. Therefore, all wells are suitable for irrigation and agriculture according to the sodium percentage. The electrical conductivity values ranged between (0.219-5200) dS/m, and therefore, most wells fall within the range of class 2 freshwater suitable for irrigation of most crops, except for wells 4 and 6, which fall within class 3, which are saline waters used for irrigation of crops that have salt tolerance and good soil permeability
