Physico-chemical and microbiological characteristics of the water samples were analysed following the standard methods to evaluate the quality of drinking water from (Raw water, Water before treatment, Water after treatment, Tap water) at the Ain Zada Dam to Bordj Bou Arreridj (Algeria) were analyzed. The results revealed that the physico-chemical and hydrochemical characteristics: (Temperature, PH, Conductivity, TDS, Turbidity, Dissolved Oxygen, Dry Residue, Ammonium, Total Hardness, Calcium and Magnesium, Chloride, Bicarbonate, Alkalinity, TAC, Iron, Manganese and Aluminum were found within permissible limits for drinking water as prescribed by WHO especially tap and after treatment water. Pearson correlation analysis, conducted to evaluate the relationship of water quality parameters, revealed a significant positive relationship between Total hardness with each of DO, Nitrate, Chlorides, and temperature (0.979, 0.961, 0.941 and 0.973) and negative significance with most of other parameters. Calcium and Sodium were correlated positively with Sulfate (0.986, 0.602 respectively). The detection of Total coliform, total germ, E. coli, Fecal Streptococci and Clostridium Sulf-Red species was intended for human consumption suggests that Raw water and Water before treatment pose severe health risks to consumers and was found unsuitable for direct human consumption without treatment. The present study recommends mobilization of treatment interventions to protect the households from further possible consequences of using the water.

groundwater) and their impact on human health as well as evaluate these water resources for different purposes at Atfih area which occupies the southern portion of Giza governorate. To achieve the aim of the present study, fifty water samples (surface water and groundwater samples) are collected during March (2016) and chemically analyzed for detection of inorganic and bacteriological pollutants. Drinking and agriculture in this area depend mainly on the water of Nile River and two main canals namely El Khashab and Masjid Musa canals as well as groundwater. The results indicated that, El Khashab and Masjid Musa canals are subjected to pollution from different sources. Also, the shallow groundwater tapped from the near surface quaternary deposits is also subjected to pollution. The socalled El Saff wastewater canal represents one of the main sources of pollution for the water resources in the study area. This canal runs longitudinally for about 50km along the foot slopes of the eastern Eocene escarpment. All the detected pollutants are considered very serious to people's health. The most important pollution problem sources include the wastewater produced from the industrial complex at Helwan area in addition to the wastewater discharged from El Saff wastewater canal into the Nile River and its canals. On the other hand, the excessive seepage of drainage water rich in fertilizers and pesticides causes pollution for groundwater. Majority of surface water (El Khashab and Masjid Musa canals) samples and groundwater samples in the study area are unsuitable for drinking as they have Fe, Sr, B and NO 3 more than that of the permissible limit.In conclusion, most of the surface water and groundwater samples in the study area are suitable for irrigation.
Quality Assessment of Drinking Water in Tanta City, Egypt
The physico-chemical and biological (algal and bacterial) quality of tap water in Tanta City were elucidated. Samples were collected during December 2011, covering all the water plants and the areal extension of the pipe line network in Tanta. Total dissolved solids content classifies water origin into surface water, shallow and deep groundwater. Fe, Mn and hardness in some samples of groundwater origin are obviously exceeding the WHO (World Health Organization) limit. Mostly, green algae are found (31 species), followed by diatoms (19 species), then blue-green algae (13 species). CCA (Canonical Corresponding Analysis) indicates that green algae are strongly correlated with pH, NH 4 , alkalinity, Mn and Si; diatoms with EC (electric conductivity), turbidity, Zn and Si and blue green algae with EC and alkalinity. 50% of samples of surface origin, 80% of samples of both deep and shallow groundwater origins crossed WHO and Egyptian guideline in their content of mean TCC (Total Coliform Count). CCA estimates strong correlations of TCC with temperature, NH 4 and PO 4 ; E. coli with EC; heterotrophic bacteria with turbidity and NO 3 ; Salmonella sp. with Si and SO 4 and Pseudomonas aeruginosa with Mn. Finally, the water plants treatment may be not effective and pipes serve as a reservoir for pathogenic microorganisms.
This study included two water purification projects for drinking water (Ifraz & Ainkawa) in Erbil city. All measurements were made such as a regular schedule at six sampling sites. Each one was visited on six occasions on fortnightly intervals periods during March to June 2005. Results showed that turbidity was ranged between (6-80NTU), electrical conductivity and total dissolved solids of the water were ranged between (236-628µs/cm) and (116-314mg/l) respectively.

Source to in-house and seasonal contamination of drinking-water quality is a persistent problem in developing countries. This study was conducted in Damot Sore Woreda, Southern Ethiopia to examine physico chemical and bacteriological quality of drinking water. For this study, four Kebele administrations were selected by purposive sampling technique. Location map and water quality sampling point were prepared using Arc GIS 9.2 software. A total of 55 water samples were taken and examined for physico-chemical and bacteriological parameters;11from source,11 from household containers,11 from drinking cup,11 for dry and 11 for wet season. One way ANOVA and correlation was employed to see the statistical difference of the variables at 5% significant level and to observe associations of variables. The result of water quality revealed that average value of all selected physico chemical parameters showed variation from source to storage. But only the value of temperature decrease significantly from supplied source to household storage (p=0.036). However, other parameters showed no significant change from source to storage. Bacteriological parameters showed variation from source to household storage and from storage to point of use. The concentration of total coliform increases significantly from supplied source to point of use (p=0.024). The dry and wet season measurement showed variations in physico-chemical and bacteriological parameters. However, statistically no significant difference observed between dry and wet season in all parameters studied. The result of water quality test revealed that average values for all selected physico-chemical parameters were found within the acceptable limit of ES and WHO standards, except Temperature and Phosphate. But the result of bacteriological water quality for all sampled sites exceeded the ES and WHO standards. So, supplied water in the area is bacteriologically contaminated and therefore not suitable for domestic purposes unless treated.
Assessment of Different Sourced Water Quality to be Suitable for Human Uses
There were two new water sources were identified in Greater Cairo. Ain Alhaya is one of the most common springs that are subjected to continuous increase in the ground water level. Ain El-Khiala is a greenish brown spring located to the south of Ain El-Sira. During the present study, samples were collected from these regions and compared to quality of water collected from River Nile, Ismailia Canal and tap water (chlorinated treated water). The physicochemical parameters, disinfection by-products (DBPs) were measured in the collected samples in addition to microbiological examination. It was showed that quality of water was the same in River Nile and Ismailia Canal. The disinfection by chlorination is effective in water treatment and enhanced the water quality as compared to the other different sourced water although it gives various by-products. As regard to the springs, it was noticed that water quality is highly better in Ain Alhaya than Ain El-Khiala. The study concluded that there were statistical correlations among the physico-chemical, microbiological and organic measurements in different sourced water as compared to river nile and the most significant correlations were noticed among microbiological and organic measurements.

The main water source is the River Nile in Benha city.The Department of Environment (D.O.E.) monitors the river basins for major contaminant sources (Chan, 2004), while the quality of the raw water reservoir is monitored by state water monitoring and controlling authorities (Hasbiyana, 2008). The main source of filtered water for Benha city is New Benha filtered water treatment plant of Atripe area with design capacity (68000 m 3 / day) which produces (56,000 m 3 / day) to pump water into the water networks. Man consumes water to survive. Clean drinking water is always needed for human health. The mortality of people aworld due to water associated diseases exceeds 5 million people per year (UN-Water, 2013). Therefore, water quality control is very important in many parts of the world (WHO, 2011). Determination of physical and chemical (inorganic and organic) parameters is very important to evaluate water quality (Dissmeyer, 2000). Contaminants in the water W ATER quality assessment of drinking water has been studied in Benha city, Qalubia Governorate, Egypt between April 2015 to March 2016 to evaluate the quality of different types of water according to physicochemical, chemical and bacteriological aspects. Twenty four samples were collected during the four seasons from different places in Benha City. Two kinds were analyzed; Benha filtered water and raw water of River Nile. The results indicated that the average values of physicochemical, heavy metals, trihalomethanes and bacteriological parameters in Benha filtered water treatment were within Egyptian standard (2007) and the World Health Organization (WHO) of water quality with comparison to raw water. The dominant bacterial isolates in the raw water samples were Escherichia coli and Enterobacter aerogenes; while the filtered water samples were 100% free from pathogenic bacteria and coliforms.
