التلوث مشكلة هامة تعاني منها المجتمعات الحديثة و وجود الملوثات في الموارد المائية و خاصة العذبة يجعل منها مشكلة خطرة و محددة للنمو و الحياة. يهدف البحث إلى تقييم مدى صلاحية مصادر المياه الجوفية للشرب و مقارنتها مع المواصفات القياسية السورية المعتمدة في هذا المجال و كذلك حساب مؤشر الجودة لها ( مؤشر الجودة الكندي ) حيث أجريت تحاليل دورية فيزيائية و كيميائية و بيولوجية لعينات المياه المأخوذة من نقاط الاعتيان المحددة في المنطقة المدروسة على مدار عام كامل بدءا من شهر نيسان 2017 و حتى شهر آذار 2018تم خلاله قياس ( الناقلية الكهربائية – العكارة - القساوة الكلية - الأمونيوم– النتريت – النترات- الفوسفات – الكبريتات- الكوليفورم الكلي – الكوليفورم البرازي –الإيشريشيا كولي E-COLi).
Pollution is an important problem experienced by modern societies and the presence of polluants in water resources, especially freshones, makes them a serious and specified problem for growth and life.The purpose of the research is to evaluate the validity of the sources of drinking water and comparison with the Syrian Standards adopted in this field, as well as the calculation of their Quality Index ( Candian Quality Index )where periodic physical ,chemical and biological analysis of water samples taken from the specified sampling points were carried out in the studied area all the year round from April 2017 to March 2018 ,(The Electric Conductivity , Turbidity , Total Hardness , Ammonium , Nitrite , Nitrates , Phosphates ,Sulphates , Total Coliform , Fecal Coliform and E-Coli) were measured . It showed that the values of the physical and chemical parameters of the water samples taken from the specified sampling points achieved the allowed limits of the Syrian Standard for drinking water expect for some values of Total Hardness and Phosphate calcareous.Bacteriological pollution of water samples was found at specific sampling points throughout the year with Total Coliform , Fecal Coliform and E-Coli exceeded allowed limits in drinking water .Th classification of water in terms of drinking capacity for the first water source ( Defa Spring )was acceptable (medium – acceptable ) while its for the second water source ( AL-Rwameya Wells ) was very poor.

Water sources in Syrian coastal area have a great importance due to the variety of the
sources and the urgent needs to water for drinking and irrigation. Therefore great efforts
are made to protect water sources from contaminants. This research aim
ed to study some
contaminant indicators in some drinking water sources in the Syrian coastal area. The
study included determining the concentrations of nitrates, nitrites and some heavy metals
including lead, cadmium and zinc in water samples taken from five sources of water
distributed from north Lattakia to north Tartous. The results showed that the concentrations
of nitrate, nitrite and heavy metals differ depending on the water source. However, all
these concentrations were lower and within the acceptable limits of Syrian standard for
drinking water. The study concluded that water resources in the coastal area are
distinguished with their relative purity and contaminants little reach.
Groundwater is an important source of drinking water. Therefore; groundwater
contamination is a source of continuing concern. Groundwater contamination is unlike
surface water contamination, because it is difficult to define and harder to be contro
lled
and treated. It may also last for years or decades.
Deveh Spring area is an agricultural area in Lattakia. It suffers from many
environmental problems, so, it is very important to assess spring water vulnerability using
DRASTIC and create water vulnerability assessment map by GIS.
The map showed that the recharge water to Deveh Spring has a high and moderate
vulnerability to contamination. The area of high vulnerable groundwater zone is (82Km2),
which is about (48%) from the whole study area. The area of moderate vulnerable
groundwater zone is (40Km2), which is about (23%) from the whole study area. Sufficient
actions must be taken to protect water from contamination, through the integrated
management of groundwater resources.
Alsin Spring is the most important water sources in Syrian coastal area, due to it is the source of drinking water for the main cities and towns in the Syrian coast. This research aimed to study some contaminant indicators in Alsin spring and some t
aps of distribution system of Alsin drinking water, and compare the Indicators with samples of bottled drinking water from Alsin spring and three other water sources (Drekish, Bukkeen, and Alfigeh). The study included determining the concentrations of nitrates, nitrites and some heavy metals including lead, cadmium and nickel in water samples. The results showed that all water sources contain varying concentrations of lead, while the nickel and cadmium were vary in drinking water samples; The concentrations of nickel and cadmium in some samples were low while were under the detection limits in other samples. The analysis of samples of bottled drinking water showed that the samples from Alfigeh spring were the lesser contamination with heavy metals, while the samples from Alsin spring were contain highest concentrations of lead and nickel. The samples of bottled water from Bukkeen spring contain the highest level of cadmium. The results showed that the concentrations of nitrate, nitrite and heavy metals differ depending on the water source. However, all these concentrations were lower and within the acceptable limits of Syrian standard for drinking water. The study concluded that water resources in the coastal area are distinguished with their higher pure.
Proven chemical analyzes conducted in the summer of 2014 to thirty wells in the
village AL-Shamia- Latakia region, that water wells west of the adjacent village to the
seaside up to 300 m distance to the east where the salinity increases while decreasing the
East Village to become water sweet near way of Lattakia-Kassab, at a distance of 1500 m
fromn the sea beach.
Fluoride ion is present in high concentration in some regions in Syria. As
fluoride occurs naturally in water, We have studied some methods of fluoride
removal such as Nalgonda technique and activated carbon method.
In Nalgonda technique we add Al
um and lime to the water, and we have
found that fluoride removal efficiency remains constant when the initial
concentrations of fluoride changes, or when the chloride ions exists in water,
but it depends on pH, and get better when the method is investigated in two
steps. In addition, adsorption of fluoride decreases with increasing
sedimentation time, or using Ventilated lime or CaCO3 instead of Ca (OH)2.
In activated carbon method we have done different experiments by using
charcoal of coconut coir, date seeds and olive seeds. And we have found that
olive seeds carbon is better than others, and its fluoride removal efficiency
increases after impregnation with solution of 2% Al2(SO4)3.
