This research was performed to study the effect of sewage water on
the surface water of the Addelbeh Valley stream, and groundwater
on both sides of the stream in Tartous Cement Factory area.
Water samples were taken from the factory water outlet
and
Addelbeh Valley water to study the content of pollutants. We also
took groundwater samples from selected wells on both sides of the
waterway in the studied area. We repeated that process every two
months for a full hydrological cycle from July 2013 to May 2014.
We found a great increase in content of the industrial drainage
water include oils and heavy metals especially iron, copper and
zinc. For example: iron concentration in sewage water exceeded
150 mg/l in all samples. Besides sewage water and stream water
contained high concentrations of ammonia and nitrite versus low
concentration of nitrate, unlike water wells samples. The study
revealed increased EC and salts concentration markedly in wells
water due to its adjacency to the sea.
