Treated wastewater which comes from Adra Treatment Station is used for
irrigating a part of the agricultural lands at Damascus Eastern Ghota after
transferring it by a set of canals constructed for this purpose, Figure No. (1),
its area estimated
about 18000 hectares in addition to the adjacent areas for
comparison object, the irrigated land by this project is forming the main study
object of this research.
This area is considered as the most affected area by the agricultural and
industrial activities, increasing of population development due to its natural
resources on one side and its location near the capital of Damascus on the other
hand. The mean value of wastewater volume coming to the station has been
estimated at 485000 m3 per day [1]. Therefore, this project is considered as one
of the important projects which ensure an additional water resources for that
area where water demand increased specifically against decreasing water
resources of formerly years of aridity which considered as one of its reasons.
From this point, this research is aimed at clearing out quality changes
happened in the groundwater in the Eastern Ghota area which affected with
irrigation by treated water, that was due to observing the quality changes of
groundwater through a grid of wells and processing these analysis results by
making maps, diagrams, and graphs; then comparing them with adjacent areas
data, and to read out of these changes and reach knowledge of irrigation effect
range by this water on the groundwater quality.
