This research discusses the problem of drinking water shortage and distribution instability in Salamyeh city due to the current crisis. Salamyeh city dependents on Orontes River as a source for drinking water through Hama water supply facility, wh ich sufferes repeated sabbotage attacks. As a result, an emergency measure was implemented by depending on local water sources within the city, which are deep wells that produce water of sulphuric nature.Three desalination plants were provided to treat local sulphuric water producing suitable safe water, but these plants production is way less than the city needs.
Al-Sourani Dam was built to provide drinking water for inhabited villages in Sheikh Badr –Tartous, but the lake water is exposed to pollutants from several sources. In this paper, we discuss the mechanism of pollution and the appropriate measures, by determining some physical, chemical and biological characteristics of water in different sites. The results showed that turbidity and pH values arise in the autumn and winter especially in the water of tributaries compared with the water of the lake, this may be due to the activated runoff following rainfall in this period. Whereas the ammonium ion showed a significant increase in the lake's tail, that can be attributed to sewage residues from Broummana Al-Mashaeikh that threw directly into the lake. The results also showed remarkable seasonal changes concerning the total microorganisms in all studied sites, where the highest value was recorded in winter that reached 5.36 × 104 cells / 100 ml in Aine Alzaaror tributary. we conclude that the main source of pollution of lake's water, was the polluted water coming from Broummana Al-Mashaeikh, in addition to Aine Alzaaror tributary, that flows near a restaurant. The second source is Al-Wade Alakhdar tributary that feeds permanently the lake. So, the lake's water should be sterilized before using for drinking.
The research aims to assess the water quality of Alkaber Alshemaly River through field and laboratory study included identifying each of the following variables: dissolved oxygen (DO), carbonic biochemical oxygen demand(CBOD), and the river tempera ture, electrical conductivity (Cond). We have also modeled two important water-quality variables (DO and BOD) using QUAL2K river and stream surface water-quality model. The studied part of the river is an area located between 16 October dam and Alegnsa, where we have five sampling sites. The field and laboratory study showed increase in D.O values to reach the highest values in the months of March, April, January and February, and the lowest values were recorded in the months of July, August, September in all sampling sites. As a final result all D.O values in all locations were higher than the minimum allowable 5 mg/l. For CBOD5 the highest values were recorded in the months of June, July and August, and the lowest values were recorded in the months of March, December, and January at all of the sites studied. In the case of D.O and CBOD, the research showed a good correspondence between the model results and field values in the months of March, January, and November, but the correspondence was relatively less in August. In general, the study showed the possibility to use the QUAL2K model to simulate rivers-water quality in Syria.
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.
This research aims to study dynamics cyanobacteria population in the Room reservoir (in the south Syria: Sweeda), which affected by water quality environmental conditions, and seasonal. 17 genera where identified and their dynamics studied monthly during 2007, calculate the biomass of the prevail genera. The bloom was occurred in October, and the value of diversity coefficient was the highest in July in the Room reservoir, but didn't occurred in the Jouelen reservoir.
