Hydrogeochemical and Geophysical Study of Selected Deep Boreholes in Al-Hamdanyia Area, North Iraq

Al-Hamdanyia district is located east of Tigris River, northern Iraq. It is regarded as an important agricultural land. Consequently, it is necessary to give great deal to the water resources particularly the ground water. The present study deals with water level and extension of ground water reservoir through the data gathered from the drilled boreholes and vertical geoelectrical sounding. Additionally, water samples were collected and analyzed to evaluate ground water quality and its uses for different purposes. The study also concentrates on the contents of the cations; Ca2+, Mg2+, Na+ and K+ and anions; CO3=, HCO3-, SO4=, Cl- and NO3- in addition to pH, Ec, T.D.S and T.H.
The study reveals wide differences in water quality and may be related to the type of bedrocks of the ground water reservoir. Aquifers are located within Injana Fn. in the northern and northeastern parts of the study area. The aquifers are characterized by low T.D.S in comparative with aquifer within Fatha Fn. Which is located in the middle, western and western south parts.
