Treated wastewater which comes from Adra Treatment Station is used for irrigating a part of the agricultural lands at Damascus Eastern Ghota after transferring it by a set of canals constructed for this purpose, Figure No. (1), its area estimated about 18000 hectares in addition to the adjacent areas for comparison object, the irrigated land by this project is forming the main study object of this research. This area is considered as the most affected area by the agricultural and industrial activities, increasing of population development due to its natural resources on one side and its location near the capital of Damascus on the other hand. The mean value of wastewater volume coming to the station has been estimated at 485000 m3 per day [1]. Therefore, this project is considered as one of the important projects which ensure an additional water resources for that area where water demand increased specifically against decreasing water resources of formerly years of aridity which considered as one of its reasons. From this point, this research is aimed at clearing out quality changes happened in the groundwater in the Eastern Ghota area which affected with irrigation by treated water, that was due to observing the quality changes of groundwater through a grid of wells and processing these analysis results by making maps, diagrams, and graphs; then comparing them with adjacent areas data, and to read out of these changes and reach knowledge of irrigation effect range by this water on the groundwater quality.

Research summary
تتناول هذه الدراسة التغيرات النوعية التي تطرأ على المياه الجوفية في منطقة غوطة دمشق الشرقية بعد استخدام المياه العادمة المعالجة في الري. يتم نقل المياه المعالجة من محطة معالجة عدرا عبر شبكة من القنوات لري حوالي 18000 هكتار من الأراضي الزراعية. تعتبر هذه المنطقة الأكثر تأثراً بالأنشطة الزراعية والصناعية وزيادة السكان نظراً لمواردها الطبيعية وموقعها القريب من العاصمة دمشق. يهدف البحث إلى تحليل التغيرات في جودة المياه الجوفية من خلال شبكة من الآبار ومقارنة النتائج مع المناطق المجاورة لتحديد مدى تأثير الري بالمياه المعالجة على جودة المياه الجوفية. تم استخدام مجموعة من الأدوات والبرامج مثل GIS وExcel وSurfer8 لتحليل البيانات وإنشاء الخرائط والرسوم البيانية.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة جداً لفهم تأثير استخدام المياه العادمة المعالجة في الري على جودة المياه الجوفية. ومع ذلك، يمكن تحسين الدراسة من خلال تضمين مزيد من التفاصيل حول المعايير المستخدمة في تحليل جودة المياه وكيفية تأثيرها على صحة الإنسان والبيئة. كما يمكن توسيع نطاق الدراسة لتشمل فترات زمنية أطول ومناطق جغرافية مختلفة للحصول على نتائج أكثر شمولية. بالإضافة إلى ذلك، يمكن تحسين العرض البياني للبيانات لجعلها أكثر وضوحاً وسهولة في الفهم.

Groundwater is one of the major sources of exploitation in arid and semi-arid regions, Thus for protecting groundwater quality, data on spatial and temporal distribution are important. Geostatistics methods are one of the most advanced techniques f or interpolation of groundwater quality. In this research, IDW, Kriging methods were used for predicting spatial distribution of nitrate NO3 -. Data were taken from 21 wells study within eastern Damascus's Ghouta. After normalization of data, variograme was drawn. The less RSS was used, so Spherical model was the best. By using cross-validation and RMSE, the best method for interpolation was selected; Results showed that Kriging method is superior to IDW method. there is a big spatial dependence for nitrate variable that amounts to 2.2 %. Finally, maps of distribution of nitrate in groundwater were executed by Kriging method, in addition to executed maps that show goodness of groundwater for drinking and irrigation. Then it was prepared map of Probability Map of nitrate at threshold 50 mg/l.
The purpose of this research is to apply a mathematical program to calculate water and chemical balance in unsaturated soils, under the influence of different methods of irrigation, in order to monitor the amount of vertical drainage of water insi de the soil and choose a irrigation method that can reduce the phenomenon of groundwater pollution. Three irrigation methods were tested with different fertilization method. The study was conducted in the western part of Homs Governorate (AlQusair orchards).
This study includes the evaluation of the problem of seawater intrusion in Al-Bassa area in 2014 through chemical monitoring of a group of sampling wells, under certain condition that were subjected to the area during the research, representing by rainfall precipitation in the study area was only 500 mm/ year, as a result in the suspension of irrigation from 16 October lake and reuse of many abandoned pumping wells. This study founds an increasing in the salinity values in the Al- Bassa coastal area of summer in 2014, ranging between(665.6-6432mg/l)after increasing daily pumping rates, in addition to the increasing of chloride and sodium concentrations in most of sampling wells water in conjunction with high salinity levels. In the fall, the salinity values ranged between 490-950 mg / l. The geochemistry of Na/Cl indicates values less than 0.84 in most water samples during the summer, while in autumn this percentage was higher than 0.84 in most samples ,to be an indicator for marine water.
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.
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 distri buted 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.
