Hydrochemical study of free groundwater in a part of Damascus's Ghouta

An available free groundwater were classified hydrochemical, and determined its fitting for general uses in a part of Damascus's Ghouta, which suffers water deficiency, where the study carried out on groundwater samples taken from 20 wells distributed on all study area, the results show that groundwater classified hydrochemical as calcic water and non potable, and unsuitable for domestic consumption in broad part from study area, but arable and recommend to use in irrigation plants that have weak resistant to salinity, and not preferable to use in industry generally, but it's good for building and concrete works.

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.

Monitoring the quality of some invested wells water in the region of the Syrian coast (Hraesoon – Banias)

According to the chemical pollution danger in general and its danger on groundwater wells in agricultural areas particularly the inhabited ones , the scientific study was implemented to determine the concentrations of some ions in water wells within the area of Hraesoon; In addition to, monitoring their changing values which indicate the rate of chemical pollution in the study area due to existing activities. The search involves a monthly periodic physical and chemical analyzes in the invested wells in Hraesoon area , Banias city for a whole year. starting from September 2011 till August 2012 by choosing ten invested wells disterbuted in the area. The study includes the changing of temperature ,pH, electrical conductivity, and the group of negative ions (nitrate NO3 -, phosphate PO4 3-, sulphates SO4 2-, chloride Cl-) in addition to positive ions (ammonium NH4 +, Sodium Na +). The values of the studied ions have demonstrated a clear disparity in each month for the samples taken from the same wells, due to the agricultural ,human activities and climatic conditions that prevailed during the sampling dates. The recorded results show cases of chemical contamination in the water wells studied not identical the Syrian standard for drinking water (2011-2012) portend a lot of health and environmental risks, especially that many of those wells are used for drinking purposes.

A Hydrogeochemical study of ground water in the Cretaceous formations in Al Qerdaha sheet

This study conducted on 30 sample of ground water, spreaded over most of the Cretaceous formations in the studied area, in order to determine origin and quality of water and evaluate it for the purposes of irrigation and drinking. The study showed that samples taken are not of the same origin, but of the same hydrochemical type of hydrocarbons. Four sets of formed salts also detected. All samples of this study were valid for irrigation water. The samples taken from Bchuna, Al-Matn, Al- Maran, Kafrdabel, Kassaben sites were safe for drinking, the rest of the samples were not because of the increase of calcium ions concentration. The sample of Ain-Kataa site had an increase in concentration of bicarbonate and potassium ions. An exceeded concentration of the limit of these electrolytes values for drinking water according to the Syrian Standard Specificationswas noticed.

Mapping of Groundwater Vulnerability to Contamination Using (PI) Method Study area (Marqieh and Alhousen watershed ) in Tartous

The research mainaim is Mapping of Groundwater Vulnerability to Contamination Using (PI) Method toevaluatethe study area (Marqieh and Alhousen watershed ) in Tartous governorate. The area of study forms a part of the coast basin, on the east coast of the Mediterranean Sea, located north of the Tartous governorate between , 34 5000,35 1000latitude in the north of the equator, and , 35 5000,36 2000 longitude in the east of the Greenwicharea covers about 700 Km2. The PI method is a GIS-based approach(We use ARCGIS .10 and the tool : Spatial Analyst Tools) , and gives special methodological tools for karstic aquifer , geological conditions , climate , relief , land use , all these conditions are mapped separately as individual maps and then integrated to achieve the groundwater vulnerability map. all the maps related to the study area was created in digital form and apply analysis processes to create vulnerability map which is a map divided to the fields and every field represents the possibility of contamination of groundwater in this region, whether high or low . The results obtainedfrom this study indicate that about 41% of the study area is under high groundwater vulnerability, 59% is under moderate, low and very low vulnerability.

Bacterial study of groundwater samples from Homs Governorate

The bacterial case of groundwater samples from Homs Governorate was studied to determine the bacterial load, Twenty-eight groundwater samples were collected from various areas (including areas of the western, northern and eastern governorates of the governorate) between March and July 2017. Where they were collected in sterile glass containers after opening and running the water for 5 minutes to avoid any external contamination.

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 .
