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.

Groundwater is an important source of drinking water. Therefore; groundwater contamination is a source of continuing concern. Groundwater contamination is unlike surface water contamination, because it is difficult to define and harder to be contro lled and treated. It may also last for years or decades. Deveh Spring area is an agricultural area in Lattakia. It suffers from many environmental problems, so, it is very important to assess spring water vulnerability using DRASTIC and create water vulnerability assessment map by GIS. The map showed that the recharge water to Deveh Spring has a high and moderate vulnerability to contamination. The area of high vulnerable groundwater zone is (82Km2), which is about (48%) from the whole study area. The area of moderate vulnerable groundwater zone is (40Km2), which is about (23%) from the whole study area. Sufficient actions must be taken to protect water from contamination, through the integrated management of groundwater resources.
The Drastic method has been used to assess the potential sensitivity of the Groundwater In Lattakia basin using Arc GIS 9.2 Where the modified Drastic system has been developed by combining the land uses and its divisions with general Drastic model .As a result, final values of Drastic have been modulated into two categories "low and moderate sensitivity" It has been found that the introduction of the human criteriahas increased the potentialof the moderate sensitivity of the Groundwater. As a final result, the general content of the sensitivity map which has been establishedfor Lattakia basin, showed, the domination of low sensitivity category in the north western and the north eastern areas which has big location depths of the Groundwater and high topographic altitudes.In contrast, the moderate sensitivity category dominated in the southern areas of the study region. The latter areas which are characterized by the existence of varied human activities havelocation ofGroundwater levels close to the surface.
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.
The provision of adequate drainage and the accompanying problem of accumulation of salt in soil have plagued irrigated agriculture for centuries. Soil salinity is one of the major problems in arid and semi-arid zones. In Euphrates valley the high groundwater level and its high evaporation rate caused a serious salinity problem. This study was aimed to allocate the dangerous areas in terms of high water level resulted from the recent and expected activities. Drainage wells will be drilled at these areas in order to lower the groundwater level and prevent further soil salinity.
The third sector of lower Euphrates basin has a great economic importance, but some lands have gone out of service because of salinization due to the rise of groundwater levels. Thus, it is very important to solve the ground water issue using new s cientific techniques. This research aims to solve the drainage problem in the third sector using a scenario based on a mathematical model, the results of which allow us design a proper drainage network comprised of 111 wells scattered all over the study area, with a total abstraction of 269000 m3/day. This will lower the groundwater level, dry the swamps, and decrease the soil salinity, ensuring a sustainable economic exploitation of agricultural lands.
