Al-Sourani Dam was built to provide drinking water for inhabited villages in Sheikh
Badr –Tartous, but the lake water is exposed to pollutants from several sources. In this
paper, we discuss the mechanism of pollution and the appropriate measures,
by
determining some physical, chemical and biological characteristics of water in different
sites.
The results showed that turbidity and pH values arise in the autumn and winter
especially in the water of tributaries compared with the water of the lake, this may be due
to the activated runoff following rainfall in this period. Whereas the ammonium ion
showed a significant increase in the lake's tail, that can be attributed to sewage residues
from Broummana Al-Mashaeikh that threw directly into the lake. The results also showed
remarkable seasonal changes concerning the total microorganisms in all studied sites,
where the highest value was recorded in winter that reached 5.36 × 104 cells / 100 ml in
Aine Alzaaror tributary.
we conclude that the main source of pollution of lake's water, was the polluted water
coming from Broummana Al-Mashaeikh, in addition to Aine Alzaaror tributary, that flows
near a restaurant. The second source is Al-Wade Alakhdar tributary that feeds permanently
the lake. So, the lake's water should be sterilized before using for drinking.
The research mainaim is Mapping of Groundwater Vulnerability to Contamination
Using (PI) Method toevaluatethe study area (Marqieh and Alhousen watershed ) in
Tartous governorate. The area of study forms a part of the coast basin, on the east coast
of the Mediterranean Sea, located north of the Tartous governorate between , 34
5000,35 1000latitude in the north of the equator, and , 35 5000,36 2000
longitude in the east of the Greenwicharea covers about 700 Km2. The PI method is a
GIS-based approach(We use ARCGIS .10 and the tool : Spatial Analyst Tools) , and
gives special methodological tools for karstic aquifer , geological conditions , climate ,
relief , land use , all these conditions are mapped separately as individual maps and then
integrated to achieve the groundwater vulnerability map.
all the maps related to the study area was created in digital form and apply analysis
processes to create vulnerability map which is a map divided to the fields and every field
represents the possibility of contamination of groundwater in this region, whether high or
low .
The results obtainedfrom this study indicate that about 41% of the study area is under
high groundwater vulnerability, 59% is under moderate, low and very low vulnerability.
This study aimed at determining some indicators of water quality in Lattakia dams within ten years (2002-2011).The indicators(pH, Electrical conductivity,Total Hardness, ca Hardness, Mg Hardness, Alkalinity, Phenol Alkalinity) in five dams (Balloran,
16 Tishreen, Al-thawra, Al-safarkia and Al-hweez) were studied. The resultsshowed thatpH, Electrical conductivity,Total Hardness, Alkalinity, Phenol Alkalinity, were within the allowed limits according to Syrian standards for drinking and irrigation water and which indicate the presence of pollution water sources.
