المياه الجوفية هي خزان احتياطي و استراتيجي للمياه العذبة المخزنة و تمثل أهم مصدر لمياه الشرب في العديد من بلدان العالم، تتعرض المياه الجوفية إلى العديد من الملوثات الناتجة عن مصادر متنوعة و من أهمها الملوثات الناجمة عن النشاطات الزراعية و الحضرية و التي أصبحت اليوم مشكلة عالمية. يهدف البحث إلى دراسة بعض الخصائص الفيزيائية و الكيميائية للمياه الجوفية في منطقة سهل جبلة في اللاذقية، من خلال قطف عينات من المياه الجوفية من منطقة الدراسة و قياس بعض البارامترات الفيزيائية و الكيميائية فيها (درجة الحرارة، العكارة، الناقلية الكهربائية، pH، الفلور، الكلور، النترات، النتريت، الكبريتات). أظهرت النتائج أن درجة حرارة المياه الجوفية و ناقليتها و pH تقع ضمن الحدود المسموح بها حسب المواصفة القياسية السورية لمياه الشرب، بالمقابل تجاوزت قيم بعض الشوارد الحد المسموح به، مثل النترات التي وصل تركيزها إلى 177mg/l، مما يشير إلى وجود بعض مؤثرات تلوث هذه المصادر المائية بهذه المادة.
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 .

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.
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.
The idea of spatial interpolation stands of great importance depending on the accuracy of
estimated (Hydrogeological) parameters of this area, which reduces excessive efforts to
reach the best Hydrogeological model of the region with as little as p
ossible, thus reducing
the overall cost of the project.
The studied area is located within the Sin plain (the southern part of the JABLEH plain).
A free layer of water, ranging between 1m and 30m in thickness.
The study relied on groundwater level data, soil thickness and type in 339 wells.
The importance of this research Lies in mapping the best spatial distribution of
characteristics using spatial statistical methods
The aim of the research is to estimate the Coefficient of Permeability of the aquifer layer
and its effective thickness using the two methods of spatial statistics methods (Kriging and
IDW) for Hydrogeological parameters in the southern part of the Jableh plain.
This research has included quarterly and periodically physical and chemical analysis of treatment wastewater in the Latakia countryside during year 2011 by testing three treatment plants similar in the mechanism of action and distributed in three v
illages (Happit, Al-Harah, Marg Moairban).
This study has included the measurement of temperature, pH, dissolved oxygen, turbidity, and determination of nitrate, phosphate, sulfate, and chloride.
In this research, potentiometric using Selective Electrodes ISEs, the Visible Spectrum, and the Turbidimetry methods were used.
The results showed significant differences in concentrations of the studied ions between one station to another. The highest nitrate concentrations (228.33mg/l) were recorded in Happit treatment plant especially in summer, and the highest phosphate concentrations (41.81mg/l) were in Happit treatment plant in summer. Whilst the highest sulfate concentrations which ranged between (508.67– 1157.33)mg/l were in Al-Harah treatment plant at all seasons. The highest chloride concentrations (310.33mg/l) recorded in Happit treatment plant in summer.
The statistical study has demonstrated and showed high and sometimes low correlation coefficient R2 so that gives clear indications about the sources of pollution.
The contamination of groundwater with nitrates is a common problem in many countries of
the world, especially the agricultural ones where the pollution originates in these countries
mainly from the use of excessive fertilization in agricultural are
as, industrial waste,
sewage, animal dung, and the "installation of air nitrogen by plants, the nitrogen
compounds that arise due to some industries and vehicle emissions which are deposited on
the ground in solids.
The nitrate compounds are carcinogens and hazardous to human health If they were in
high concentrations. The risk of this turning into nitrite nitrate uptake by the bacteria,
especially in the abdomen which in turn causes what is known as Balmithmoglubenemea
in infants and pregnant women (Infant disease blueness). It can also cause stomach cancer
in adults through its interaction with amines and amides in the abdomen, forming
carcinogens (Alntrozzomedat and Alentrzoaminat). Therefore, you must apply the
foundations of the integrated management of groundwater in the study area to maintain
low levels of nitrate in groundwater used for drinking and irrigation.
