The big value of dams in the Syrian coast comes from using them for irrigation and sometimes as source of potable water. This study aimed to determine some chemical indicators of water quality in Lattakia dams during ten years (2002-2011). The
conce
ntrations of ions (Cl-1, SO4-2, NO2-1, NO3-1, PO4-3, K+1, Na+1) in five dams (Balloran, 16 Tishreen, Al-thawra, Alsafarkia and Alhweez) were studied. The results indicated that most of the ions showed significant difference in concentrations during 2002-2011.The ions concentrations in most studied dams increased. The increase related to characteristics of dams (location, capacity, the activities located around the dam…).
This research aims to evaluate the water quality of the Al-Sain lake which feeds
mainly the Lattakia city and a part of the Tartous city of drinking water purpose.
In this paper, we study a group of physical and chemical factors for the water of th
e
Al-Sain lake during the years of available data (1991-2004-2007-2011), samples were
taken from four different locations according to the program approved by the concerned
staff to monitor and protect the lake, namely: (Lattakia water supply point, Tartous water
supply point, irrigation point, southern spring observatory), and we calculated the quality
index for drinking purposes using US approved methodology of National Sanitation
Foundation. Nine factors have been adopted: (dissolved oxygen, fecal coliforms, pH,
BOD5, temperature, phosphate, nitrates, turbidity, and total solids).
The research result showed that the classification of water quality was good in all
four monitoring points during the years 1991 and 2004, noting a significant improvement
of the quality in 2004, and decreases slightly during the years 2007 and 2011 for
monitoring points in the Lattakia water supply and irrigation points, but water quality still
keep maintain a good classification, while the quality of the water goes down within the
threshold of middle classification for the Tartous and southern spring observatory
monitoring point.
The research aims to determine a water Quality Index for the Lake of 16 Tishreen
Dam. To achieve this aim we have carried out a different periodical physicchemical and bacterial measurements on the water of the lake. The Samples were
taken at five
sites along the lake for a period of complete year. The indicators that
، NO2، NO3، BOD5، DO، EC، PH، Turbidity،have been measured are: Temperature
and ، F.C. Measurement results were represented diagrammatically،PO4،NH4
compared with the Syrian Specification Standards for portable Water. The lake was
Canadian Indices ، classed according to these Indices: Malays quality index
(NEWWQI). The Lake was Classed according to these indices as ،(NSFWQI)
from second grade at ،following:from third grade at all locations (Malays Index)
and from ،the middle lake and from a third grade to all other locations (NSFWQI)
second grade at all locations (NEWWQI). According to this indices the water is
not good for drinking and needs treatment. The Productivity of the lake was
determined. The Lake is Eutrophic according to TN-TP in the middle but
Hypertrophic accordingtoTN-TP in all other location
