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.

Research summary
تتناول هذه الدراسة تقييم نوعية مياه الشرب في منطقة الشامية بمحافظة اللاذقية من خلال تحليل الخصائص الفيزيوكيميائية للمياه. أجريت التحاليل الكيميائية في صيف 2014 على ثلاثين بئراً في القرية، ووجدت أن الملوحة تزداد في الآبار القريبة من شاطئ البحر وتتناقص كلما اتجهنا شرقاً حتى تصبح المياه حلوة عند طريق اللاذقية كسب على مسافة 1500 متر من الشاطئ. تم استخدام أجهزة متخصصة لقياس تراكيز الشوارد المختلفة مثل الصوديوم، البوتاسيوم، الكلور، والكربونات، بالإضافة إلى قياس الناقلية الكهربائية ودرجة الحموضة (pH). أظهرت النتائج أن تراكيز الشوارد والملوحة تتفاوت بشكل ملحوظ بين الآبار الغربية والشرقية، حيث تكون الملوحة أعلى في الآبار الغربية وتتناقص تدريجياً باتجاه الشرق. كما تبين أن استنزاف المياه الجوفية للري كان له تأثير كبير على نوعية المياه، وأن استخدام مياه سد 16 تشرين لري المنطقة ساهم في تحسين نوعية المياه الجوفية. توصي الدراسة بضرورة القيام بدراسات دورية لنوعية المياه ووضع قوانين للحد من استنزاف المياه الجوفية.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة جداً في سياق تقييم نوعية مياه الشرب في منطقة الشامية، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، كان من الأفضل تضمين المزيد من البيانات حول تأثير العوامل المناخية والموسمية على نوعية المياه. ثانياً، الدراسة ركزت بشكل كبير على التحليل الكيميائي دون النظر إلى الجوانب البيولوجية التي قد تكون لها تأثيرات كبيرة على نوعية المياه وصحة السكان. ثالثاً، كان من الممكن توسيع نطاق الدراسة ليشمل مناطق أخرى في الساحل السوري للحصول على صورة أشمل وأدق. وأخيراً، يجب أن تكون هناك توصيات أكثر تفصيلاً حول كيفية تحسين إدارة الموارد المائية في المنطقة.

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.
Drinking water is too neccessary for everyone .It must be pure and healthy.Turbidity is one of the most important problems in water .It may cause damage for humanbeings . So it must be controlled. This search aims to determine the suitability of dosing AL2(SO4)3·18 H2O, ,FeSO4.7H2O with the intention of reducing turbidity levels to acceptable limits . In the present study , a series of jar test was conducted to evaluate the optimum pH, dosage and performance parameters for coagulants,.We studied the effect of AL2(SO4)3·18 H2O, ,FeSO4.7H2O dosage on reducing of turbidity, The influence of pH on turbidity reducing , and the effect of slow mixing time on turbidity . And turbidity reducing by AL2(SO4)3·18 H2O was removed 96 % of the total turbidity. And turbiditu reducing by FeSO4.7H2O was removed 98 % of the total turbidity.
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.
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.
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.
