Underground water is extracted by wells that are connected through underground canals. Thus, the levels of pollutant elements in ground water could be evaluated directly from water samples collected from the wells. This study was conducted in the city of Samara / Salah-Aldeen province – Iraq. The samples were taken from 29wells within the study area for the period 2012-2014 with a supervision from the General Authority for Groundwater / the Iraqi Ministry of Water Resources. GIS technology was adopted to calculate the pollution elements at Samara water table. The concentrations of chemical elements [K, Na, Mg, Cl, Ca] and compounds [SO4, HCO3] were manipulated and calculated for the entire area. The results of laboratory analyses showed that the groundwater in this area is not suitable for use as drinking water for humans, since the concentrations of the chemical elements and the compounds exceeded the permissible limits and are not in accordance with WHO standards. However, the results also indicated that the groundwater in the covered area is suitable for agriculture irrigation.

The Tarat aquifer provides drinking water for the population of the city of Arlit and also provides water to industries. The exploitation of this aquifer has considerably increased in recent years. The main objective of this study is to contribute to a better understanding of the functioning of the Tarat aquifer. Thus, a methodological approach focusing mainly on the piezometric study and the analysis of evolution and estimation of the volumes of water pumped, since its development from 1969 to 2012, which has resulted in highlighting not only a general decline in the level of the Tarat aquifer, but also the piezometer level (Arli_182), reacts strongly to the solicitations of the aquifer. On this same piezometer, the water table was lowered by 30 m from 1980 to 2006 (26 years), so a drawdown of 0.86 /year.

The study of fluorine content in the natural waters of the Odesa region was carried out. The content of fluorine in the waters of the centralized and non-centralized drinking waters supply of the Odesa region and the city of Odesa is determined. Areas with low and high fluorine content are found. Very low fluorine content is determined in Kiliyskyi, Bilyaivskyi, Kodimskyi and Savranskyi districts of the Odessa region. High fluorine content (above MAC) is determined in the Tarutinskiy and Arzizkyi districts. Correlation dependence of fluorine content in drinking water of the Odesa region and indicators of the prevalence of dental diseases (caries and fluorosis of teeth) of the population of the region and the city are established. It is determined that for most districts of the region there is a relationship between the content of fluorine in drinking waters and dental health. In some areas, this dependence is not sufficiently expressed, which is due to the geochemical and ecological characteristics of the territory. It is revealed that for the population of Odesa, who use water with very low fluoride content, high indicators of the disease for caries and fluorosis of teeth are characteristic, which is connected with the allocation of industrial areas with significant anthropogenic loading, including fluorine compounds. One of the possible causes of dental disease, even with optimal fluorine content in drinking water, can be the combination of its action with other chemical elements. Key words: fluorine, drinking water, Odesa region, Odesa city, caries and fluorosis of teeth.

Due to water resources shortage in Saudi Arabia, the water authority relies on intermittent water supply system. In this system, the city is divided into a number of small sectors, and water is pumped rotationally between the sectors according to an operational schedule. The frequency of water pumping to a given sector varies from several days to weeks. Between the intermittent water supply, pipes remain empty and dry for long periods. Consumers construct the underground storage water tanks to meet their demands. Lack of sewerage systems in many areas with high water table in the city lead to the presence of cesspools near the underground storage water tanks. Potential leakage of polluted water into the distribution network is very high and the pipe system is exposed to the pressure of contaminated surrounding water table. These factors enhance the risk of drinking water contamination. The first objective of this study is to assess the quality of domestic water supply in Jeddah. One hundred and thirteen water samples were collected in a five-month period between January and June 2009. Thirteen parameters were evaluated and compared to the maximum level of the WHO and Gulf standards for un-bottled drinking water. The results showed a compliance with the drinking water standards regarding the physical and chemical parameters, except five samples which have exceeded the maximum allowable limit for iron. The bacteriological results showed that up to 60% of the samples were contaminated with total coliform. The second objective is to evaluate the suitability and reliability of the most purchased domestic water purification units (point-of-use) POU, and to select the suitable water purification unit for the residential water in Jeddah. Unit III, which consists of fiber filters, activated carbon filter and the ultraviolet UV- Sterilizer of ultraviolet (UV), was found to be suitable for domestic use in Jeddah

The Paris drinking water system has the particularity of being supplied by many different sources: surface water from the Seine and Marne rivers and underground water from sixty-three springs. This diversity of origins of the water and the existence of a gridded network leads the company in charge of the production and the quality of the water in Paris, Sagep, to partly mix the water in the network. Knowing the impact of the mixing on the physical parameters, and consequently on the quality of this mixed water, Sagep had searched for a tool to control the water origins in the network in order to limit extreme changes. A study led Sagep to develop a new kind of real-time water mixing model.

The presence of some chemical compounds at higher levels than maximum permissible concentrations (MPC) in the drinking water, suggests of water resources pollution. In this paper the following elements were analyzed: total arsenic, cadmium, lead, cooper and zinc. Twelve samples of water from the water supply system from the city of Skopje were examined during one year from three different springs. Also, ten samples of bottled water from three producers from the Macedonian market were tested.The determined average mass concentrations of total As, Cd(II), Pb(II), Cu(II) and Zn(II) in the analyzed water samples from the water supply system are 1.35 μg/l, 0.06 μg/l, 0.6 μg/l, 0.9 μg/l and 1,12 μg/l, respectively, and for the tested bottled water, the mean values ranges from 0.56 - 0.83 μg total As / l, 0.053 - 0.056 μg Cd(II)/l, 0.51 - 0.54 μg Pb(II)/l , 0.6 - 0.87 μg Cu(II)/l and 0.68 - 0.8 μg Zn(II)/l water.The following instrumental analytical methods and techniques were used for the analysis of the tested samples of drinking water: flame atomic absorption spectroscopy (AAS), atomic absorption spectroscopy with hydride cеll, electrothermal atomic absorption spectroscopy.The obtained results are shown in tables and graphic form. According to the obtained results a comparative analysis was carried out indicate that it is a water of good quality that can be used in different branches of the process industry.The obtained results in this paper do not exceed the values of the MPC of the Republic of Macedonia prescribed by the legal regulations for the drinking water, which confirm the health safety of the drinking water from the water supply system in the city of Skopje and the packed waters from the Macedonian market in relation to the tested elements.

A total of 111 water samples were drawn from 15 wells. These samples were subjected to bacteriological examinations to determine the suitability of the monitored wells as source for drinking water. Significant levels of bacterial pollution indicators were detected in the underground water samples during the period of study. Total bacterial counts ranged between 10-104CFU/ml. Faecal streptococci was the most common and detected in 9 6% of water samples. Lower percentages of samples (92, 55 and 45%) were contaminated with total coliforms, faecal coliforms and total clostridia, respectively. Faecal coliforms: faecal streptococci was less than 0.7 in 86% of the examined samples. Anaerobic bacteria were detected in the examined well water samples. Only 101 water samples were tested for anaerobic spore-formers and all showed positive results. Most examined wells do not meet the water quality standards for drinking water. Accordingly, the necessity of controllin bacterial pollution in ground-water through disinfection was clearly confirmed. Testing the underground water for more than one indicator represents an important approach for water quality assurance.
