The present work deals with hydrochemistry of the major elements in Tigris River water, along the area stretching from the beginning of the river entry into Iraqi territory in the north, and to Baghdad city in the south.
The results revealed an increase in the concentrations of the major elements in general, during the trajectory of the river to the south, as well as a relative increase in the concentrations of the elements during the winter, compared with their concentrations during the summer. The result also clarified that the composition of the river basin rocks plays the main control of the major elements hydrochemistry. The results indicated that the controlling rocks type of the Tigris main reservoirs are rang between carbonate and silicate compositions.

The present work, deals with hydrochemistry and water quality of some
shallow wells in Wana area, northern Iraq and its validity for irrigation, through
the physical and chemical analyses of 13 water samples selected from these wells
distributed in the study area.

The results revealed that there are two factors controlling the hydrochemistry
of water in the area. The first is natural factor represented by type of rock
components of the studied area, and the second is anthropogenic factor which is
human activities. Owing to the natural factor, the analyzed water tend to be of non
carbonate hardness by the influence of the evaporates of Fat'ha formation. Despite
the great influence of Fat'ha formation rocks on water quality in the area, however
the direct feeding of Tigris river to the well waters prevents the increasing of the
concentration of ions and this made these waters valid for irrigation purposes.

Study of the Incrustation Tendency of Groundwater on a Filter Pipe of Water Wells for Selective Areas Around Mosul City

ABSTRACTWater tends to deposit mineral on the screen (filter) surface and in the pore spaces of the formation just out side the filter, such deposit plug both the filter openings and the formation. Twelve water samples were collected from different formations/aquifers around Mosul City and analyzed to show their tendency to incrustation. The incrustation tendency for each sample was calculated and showed that it is changing from 0.02 to 130 in Al-Mahed1 and Mishraq localities respectively.
