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 taps 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.

Research summary
تهدف هذه الدراسة إلى مقارنة تركيزات بعض الملوثات في مياه الشرب المستجرة من نبع السن والمياه المعبأة من مصادر مختلفة في المنطقة الساحلية السورية. تم تحليل تركيزات العناصر الثقيلة مثل الرصاص والنيكل والكادميوم، بالإضافة إلى النترات والنتريت في عينات المياه. أظهرت النتائج أن جميع المصادر المائية تحتوي على الرصاص بتركيزات متفاوتة، بينما كانت تركيزات النيكل والكادميوم منخفضة في بعض العينات ودون حد الكشف في الأخرى. كانت المياه المعبأة من نبع الفيجة الأقل تلوثاً بالعناصر الثقيلة، بينما كانت المياه المعبأة من نبع السن تحتوي على نسب مرتفعة من الرصاص والنيكل. أما المياه المعبأة من نبع بقين فكانت الأكثر تلوثاً بالكادميوم. كانت تركيزات النترات والنتريت منخفضة في معظم العينات ودون حد الكشف في بعضها. خلصت الدراسة إلى أن تركيزات الملوثات في المياه المستجرة والمعبأة كانت أقل من الحدود المسموح بها وفقاً للمواصفة القياسية السورية لمياه الشرب، مما يشير إلى نقاوة عالية للمصادر المائية في المنطقة الساحلية وانخفاض نسبة الملوثات التي تصل إليها.
Critical review
دراسة نقدية: على الرغم من أن الدراسة قدمت تحليلاً شاملاً لتركيزات الملوثات في مياه الشرب، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل توسيع نطاق الدراسة لتشمل فصولاً مختلفة من السنة، حيث يمكن أن تتغير تركيزات الملوثات مع تغير الفصول. ثانياً، لم يتم التطرق بشكل كافٍ إلى تأثيرات الملوثات على الصحة العامة، وكان من الممكن تضمين توصيات أكثر تفصيلاً حول كيفية تحسين جودة المياه. ثالثاً، كان من الممكن استخدام تقنيات تحليلية أكثر دقة وحداثة لتحسين دقة النتائج. وأخيراً، لم يتم مناقشة تأثيرات الأنشطة البشرية المختلفة بشكل كافٍ على تلوث المياه، وهو ما يمكن أن يضيف قيمة إضافية للدراسة.

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.
A total of 370 bottles of noncarbonated natural mineral water (domestic and imported) with different bottling dates, were collected directly from the markets in Syria one word one year 2006. Bacterial diversity was approached with tentative identification of the strains isolated using biochemical and enzymatic criteria (with the aid of API 20 NE identification system for nonfermenters).
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.
Groundwater is a reserve and strategic reservoir of stored fresh water، It is the most important source of drinking water in many countries of the world. Groundwater is exposed to many pollutants from a various sources. The most important of these sources are pollutants from agricultural and urban activities، which are now a global problem. The research aims to study many physical and chemical properties of groundwater in Jableh plain in Lattakia, by collecting samples of groundwater from the study area and measuring a number of physical and chemical parameters (temperature ،turbidity، electrical conductivity ، pH ، fluoride، chloride، nitrates، nitrite and sulphates (.The results showed that temperature، conductivity، pH were within the allowed limits according to Syrian standards for drinking water. In contrast، the concentrations of some ions exceeded the allowed limits، such as nitrates,which it's concentration is up to 177mg / l، Indicating that there are many factors cause contamination of these water sources with nitrate .
