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.
