تكتسب مصادر المياه في المنطقة الساحلية في سورية أهمية كبيرة نظراً لتنوع مصادر هذه المياه و الحاجة الكبيرة إليها كمصادر لمياه الشرب و الري، و انطلاقا من ذلك تبذل جهوداً كبيرةً للحفاظ على سلامة هذه المصادر و منع الملوثات من الوصول إليها. هَدَفَ هذا البحث إلى دراسة تركيز بعض الملوثات الكيميائية في بعض مصادر مياه الشرب المنتشرة في المنطقة الساحلية . و شملت الدراسة قياس تراكيز كل من النترات و النتريت و بعض المعادن الثقيلة مثل الرصاص و الكادميوم و التوتياء في عينات مياه أُخذت من خمسة مصادر مياه تمتد من شمال اللاذقية إلى شمال محافظة طرطوس. أظهرت النتائج أن المصادر المائية جميعها تحتوي النترات و النتريت و المعادن الثقيلة المدروسة بتراكيز تختلف حسب المصدر المائي و لكن جميع هذه التراكيز كانت منخفضة و تقع ضمن الحدود المقبولة وفقاً للمواصفة القياسية السورية لمياه الشرب. خلصت الدراسة إلى أن المصادر المائية في المنطقة الساحلية تتميز بنقاوتها نسبياً و انخفاض نسبة الملوثات التي تصل إليها.
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 aimed 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.

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.
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.
The effect of adding two organic acids(formic acid, acetic acid). with broiler drink
water was tested to evaluate their efficacy on the their performance and health Groups
treatment consumed amounts of feed that are greater than the control but for
The results in
the six trials showed superiority of the feed conversion ratio and the final weight of broiler
in the two groups that was added complex to its drink water, compared to the control with
significant differences at 0.05.
There was no significant difference between the replicates of each trial on its own
while the results of laboratory parasite testing of samples litter showed that the number of
oocysts in the litter was the lowest in the treatment groups with significant differences
compared to the control. It was noted that the number of oocysts in litter increased until a
certain age and then began to decline.
The results also showed reduced mortality in all trials with treatment and there were
no significant differences in treatment groups compared to the control.
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.
