Study of some physical and chemical parameters of the Addelbeh Valley water and groundwater in the area of Tartous Cement Factory

This research was performed to study the effect of sewage water on the surface water of the Addelbeh Valley stream, and groundwater on both sides of the stream in Tartous Cement Factory area. Water samples were taken from the factory water outlet and Addelbeh Valley water to study the content of pollutants. We also took groundwater samples from selected wells on both sides of the waterway in the studied area. We repeated that process every two months for a full hydrological cycle from July 2013 to May 2014. We found a great increase in content of the industrial drainage water include oils and heavy metals especially iron, copper and zinc. For example: iron concentration in sewage water exceeded 150 mg/l in all samples. Besides sewage water and stream water contained high concentrations of ammonia and nitrite versus low concentration of nitrate, unlike water wells samples. The study revealed increased EC and salts concentration markedly in wells water due to its adjacency to the sea.

Study of some quality indicators of drinking water in some drinking water resources in Syrian coastal area

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.

The Use of Technology of the Fermentation to Produce the Biogas from the cow manure

The Research aimed to use the technology of the fermentation to produce the biogas from the cow manure. The digester has benn carried according to the Indian model. The digester consit of one cylinerical tank with 9.42m3 volume (height 3m, diameter 2m) and gastank with 6m3 (height 1m) and inlet pipe and outlet pipe. The study showed the following: The accumulated production of biogas was through the 30 days retention time 48m3. The heighest production was in the thirteenth day with 4.5m3. The farm became after the use of digester clean and with little insect and smell. With use 1m3 of biogas could we use one cooker for 2.5 hour and with the same quantity could we use one inner combustion diesel motor (90% biogas and 10% diesel) for half an hour. 3/4m3 from digester volume is enough for one cow with 12 kg manure daily. So we can design the suitable digester for any farm.

Isolation and identification of Pseudomonas pachastrellae, Micrococcus brunensis bacteria from soil polluted by petroleum

Two bacterial species were isolated from petroleum hydrocarbon-contaminated soil. The isolates were characterized based on their gram reaction characteristics, morphological and biochemical properties. The results showed two bacteria isolated the first isolated: gram negative short rod, urease and nitrate reduction test showed a positive result , and glucose test showed positive result. And the second isolated: gram positive cocci, gelatin and Citrate utilization test showed a positive result , and maltose, mannitol test showed negative result. They were then incubated at (37) ° C for (48- 72) hours. This is based on comparison of results with Bergey Manual of systematic bacteriology. The isolates were identified to be: Pseudomonas pachastrellae (X1) Micrococcus brunensis (X2).

Assessment of lead contamintation of soil at northern Daraa city entrance

Soil samples were collected from three sites located at distances (0, 1500, 3000)m along the road from the northern entrance of Daraa city. For each site, samples were collected from two depths, at three distances from the road axis and from the two sides of the road. Results showed that total and available lead concentrations in soil were higher in east than west side of the road due to the effect of the dominant westerly winds in the region. the differences were significant for the total and available lead concentrations at distances (0,1500)m, and (0,3000)m at the entrance of the city, the distances (5,25)m, and (5,50)m, at the distance from two road sides, and between the depths (0-15), (15-30)cm, whereas the differences were not significant for the total and available lead concentrations at distances (1500,3000)m at the entrance of the city, and (25,50)m at the distance from two road sides. There was a very strong correlation between the average total and available lead concentration.

Studying The Quality Of Ground Drinking Water resources that supplies the region ( AL-Hannadi – Fedio ) and protecting it from pollution The state of the study ( AL-Rwameya –Defa ) spring

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.

Determination of the concentrations of some ions in groundwater for drinking purposes in Jableh plain

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 .
