“…The quality of water in general is the combination of the number of microorganisms, concentrations of chemical compounds, and physical properties; therefore, interdisciplinary studies provide the best effects in this respect. Combining hydrochemical testing with microbiological analyses of water can be a useful tool enabling multivariate analysis of obtained results, and it has proved useful in a number of studies on aquatic ecosystems, including high-alpine spring waters in Italy (Esposito et al 2016 ), groundwater of the Mamora basin in Morocco (Kabbour and Zouhri 2005 ), or groundwater of the Merdja plain in Algeria (Fehdi et al 2016 ). Harclerode et al ( 2013 ) successfully combined a geographical approach with microbiological and chemical analyses of water to track the point and non-point sources of contamination with E. coli in Texas.…”

This study was aimed to determine the anthropogenic and natural factors affecting spatial and temporal changes in the physicochemical parameters and bacterial indicators of water quality in the river Białka. The impact of intensive development of the tourist infrastructure on the quality of river water and the potential health threats to tourists was also assessed. Water samples were collected over a period of 2.5 years, once per each month in four sites along the river. Temperature, electrolytic conductivity, pH, and water level were measured onsite; flow rate data were acquired from the Institute of Meteorology and Water Management; chemical analyses allowed to determine the amount of fourteen ions, while microbiological indicators included total and thermotolerant coliforms, total and thermotolerant Escherichia coli, and mesophilic and psychrophilic bacteria. The combination of hydrological, hydrochemical, and microbiological methods generated large amount of data, which were processed by multivariate statistical analysis. A downstream cumulative effect was observed in the contamination of the river water. Fecal coliforms and E. coli were detected in all sites, suggesting the source of fecal contamination even in the protected areas. Intensive development of a ski resort and the related infrastructure, together with the need to accommodate numerous tourists in the examined region, has an evident environmental impact. The resulting deterioration of water quality poses health risks to tourists, as water from the Białka river is used for a variety of purposes, including as a raw drinking water or for artificial snowing of ski slopes. The seasonal changes in the physicochemical parameters mainly result from varying natural factors that shape the water quality in the studied region. The differences in the number of analyzed microorganisms result from seasonal variation in touristic activity and are affected mostly by point sources of sewage inflow.

“…3) indicates that several springs contain groundwater with insignificant amounts of NO -3 ( Table 1). SO [2][3][4] ions are less abundant; they represent on average 21 and 20% of all the anions, respectively. In contrast to this, the predominant anion trend is in the order HCO -3 > Cl -> SO [2][3][4] > NO -3 in the spring S5 and S8 and in cations, the order is Ca 2+ > Mg 2+ > Na + > K + .…”

A spectrophotometer UV-visible spectral photolab WTW with compatible kits is used to analyze anions Cl -, SO [2][3][4], NO -3 and metal (Fe 3+ ). Analyses have been accomplished at Civil Engineering and Hydraulic Laboratory m University of Guelma.…”

The hydrochemistry of springs in Mahouna massif, located at Guelma , north east of Algeria was evaluated for drinking water and irrigation. Ten major springs were sampled. The physical parameters (pH), Electric Conductivity (EC), Total Dissolved Solids (TDS), TH as well as the concentrations in major ions Ca 2+ , Mg 2+ , Na + , K + , Cl-, SO 4 2-, HCO-3 ,Fe 2+ and NO-3 analyzed by standard methods. Two chemical facies are predominant in the study area (Na-Cl and Ca+Mg-HCO 3). Water-rock interaction characterized by the dissolution of carbonates and silicates plays a primordial role in the chemical composition of the groundwater. The hydrochemical study of the area showed that the majority of cations and anions, electric conductivity, the TDS and the TH which characterize the chemical composition of the water springs are above the limits allowed for the drinking water according to standards. SAR, SS¨P and RSC reveal that, barring a few locations, most of the groundwater samples are safe for irrigation purposes.
