Nitrate groundwater contamination is of major interest all over the world. This problem arises in agricultural regions across Morocco. An excess amount of nitrate causes a serious problem in urban water networks and human health. Because of these health risks, considerable attention has been paid to find effective treatment processes to reduce nitrate concentrations to safe levels. The World Health Organization has set an acceptable level for nitrate in drinking water at 50 mg/L. The aim of this study is to reduce the nitrate concentration from groundwater using two membrane processes: Electrodialysis (ED) and Nanofiltration (NF). Efficiencies of these two technologies are compared in respect to nitrate ions removal, cost process and final quality of water. The results of technologies show that, for electrodialysis standards level can be achieved for a demineralization rate of 15% and the physico-chemical quality of the produced water is satisfactory. For nanofiltration we obtain a nitrate removal of 90% but the produced water is very de-mineralized and must be remineralized.

This study examined the mycological quality of groundwater in Yenagoa metropolis, Bayelsa State, Nigeria. Triplicate water samples were obtained from 8 locations in the metropolis, and the fungi quality analyzed following standard microbiological procedures. Results showed that total fungi density ranged from 5.2±1.00 x102 to 8.50±0.56 x103 CFU/ml. Analysis of variance indicates statistical variation (p=0.001) across locations with total fungi density exceeding the limit of 102 CFU/ml specified by World Health Organization/Food and Agricultural Organization for potable water in 62.50% of samples. Eight fungi isolates (species) were identified in the study with frequency across the locations as follows: Aspergillus flavus (20.59%), Aspergillus fumigatus (20.59%), Aspergillus niger (20.59%), Cladosporum (5.88%), Fusarium (2.94%), Mucor (8.82%), Penicilium (14.71%) and Rhizopus (5.88%). Of these, Aspergillus species were predominant across the locations. Since groundwater meets diverse purposes, it is essential that it is suitable for the desired use, and this can be done using appropriate technology to make groundwater potable for human consumption.

Some special diagrams for evaluating the chemical properties of groundwater intended for human consumption are introduced, in accordance with the Italian legislation assimilating EEC Directive 91/271 concerning the treatment of urban waste water and EEC Directive 91/676 related to the protection of waters against contamination by nitrates from agricultural sources. Although the limits imposed by the legislation reflect the Italian situation, they do however conform to directives concerning the whole European Community and offer a response to international guidelines promulgated by, for example, the World Health Organization so they are also suitable for use in national contexts other than Italy. Moreover, a diagram is introduced for monitoring the quality of water destined for agriculture, in particular for irrigation and the special issue of soil protection. In this case, in the absence of specific national and/or European laws and/or Directives, reference was made to the standards of the California Water Quality Control Board. The parameters and the relative limits have been taken from such standards, to identify three quality classes of water for agricultural use with evaluation of use. Plotting such diagrams is very simple: they can be used for improving presentation and interpretation of chemical data and, most of all, to provide comparisons between different water resources or to evaluate possible changes over time. Some examples, reported in the text, will aid understanding their use and interpretation.

The results of the study of ecological and geochemical features and assessment of the water quality of water sources located on the territory of the Semipalatinsk test site are presented. The studied waters are diverse in chemical composition: 14 % of the samples had hydrocarbonate, 69 % – sulfate, and 17 % – chloride types of waters. On the basis of the revealed features of the elemental composition of the underground waters of the Semipalatinsk test site, decreasing series of excess of the average concentrations of elements in water in relation to the composition of waters of the zones of hypergenesis and continental salinization were constructed: U14 > Mo8 > Sr8 > V3 (hypergenesis zone), U5 > Mo3 > Sr3 > V2 (zone of continental salinization). For the groundwater of the Semipalatinsk test site, specific elements were identified, such as U, Mo, Sr and V. The water quality was assessed for the studied chemical components based on comparison with the standards of the Republic of Kazakhstan and the World Health Organization (SaNPiN No. 209, WHO 2011).

The key to provide microbiologically safe drinking-water lies in understanding the various mechanisms by which water gets contaminated. This study assessed the risk of contamination and microbiological and chemical quality of water from protected dug wells in five selected Panchayats in Kollam district, Kerala state, southern India. Sanitary inspection was conducted for 70 protected dug wells using World Health Organization established procedures for risk of contamination scoring. Microbiological and chemical analysis of water samples was done. The areas with higher incidence of hepatitis A had a higher proportion of wells with high risk of contamination scores (p = 0.006). High risk of contamination scores for wells were associated with higher incidence of fecal pollution (odds ratio 11.80; 95% confidence interval 1.87–74.86). The study highlighted the need to make the wells safe in this area, for control of waterborne diseases.

Abstract An assessment of consumer quality perception, as well as some physical and chemical characteristics of water samples sourced from wells, boreholes, and rivers in the locality of Pelengana commune, in Mali, was carried out. The World Health Organization (WHO) Guideline (or other) Values (GVs) for drinking water quality was used as a benchmark. One-way analysis of variance (ANOVA) alongside Duncan's multiple comparison tests for significant differences, and Principal Component Analysis (PCA) were used in analyzing differences and correlations regarding the parameters investigated. Results revealed that the majority of the households (61.2%) regarded wells and river water as unsafe for drinking. The physical and chemical quality of water was affected by climatic season. Also, with the exception of iron (average values), the parameters studied met the WHO GVs. Based on the analyzed parameters, the quality of these different water sources is chemically acceptable.
