The present study was carried out to investigate the desmids biodiversity in traditional freshwater reservoirs of Nagaur district, Western Rajasthan, India. The samples were collected in January 2021 from the freshwater small ponds which harvests rainwater located in and around Nagaur city. These samples were analyzed by following the standard method prescribed by A.P.H.A for assessing the various physicochemical parameters such as pH, TDS, Fluoride, Nitrate, Chloride, total alkalinity, and total hardness to check drinking water quality and for ecological assessment. Furthermore desmids species-level identification and description have been done with the help of standard literatures and monographs. Results of physicochemical parameters indicate the deteriorating drinking water quality of all four sampling sites. In the present study total of 16 species belong to 5 genera i.e. Netrium, Closterium, Cosmerium, Staurastrum, and Eustrum of desmids have been recorded for the first time from the freshwater ponds located in or around the Nagaur city. The higher biodiversity of Closterium and Cosmarium species at Jhada talab confirm its significant relationship with high calcium and nutrient-rich water quality. While low biodiversity of desmids at remaining all village ponds indicates that high pH and oligotrophic quality decreases the desmids biodiversity. Results of this study might be helpful to assess the geographic distribution of desmids flora of Nagaur district and establish water quality of protected freshwater habitats as well as in updating the list of current species of desmids in this sub-region.

Safe source of drinking water is always considered as an essential factor in water supply for cities and urban areas. As a part of this issue, drinking water quality is monitored via a useful scheme: developing drinking water quality index DWQI. DWQI is preferably used as it summarizes the whole physicochemical and bacteriological properties of a drinking water sample into a single and simple term. In this study, an evaluation was made for three drinking water treatment plants DWTPs named: Efraz 1, Efraz 2 and Efraz 3 that supply drinking water to Erbil City. The assessment was made by testing thirteen physicochemical and two bacteriological parameters during a long period of (2003 – 2017). It has been found that turbidity, electrical conductivity EC, total alkalinity, total hardness, total coliform and fecal coliform have more influence on drinking water quality. DWQI results showed that the quality of drinking water supplied by the three DWTPs in Erbil City fallen within good level. Except various occasional periods where the quality was varying from good to fair. The quality of the drinking water supply never reached the level of marginal or poor over the time investigated. The applied hierarchical clustering analysis HCA classifies the drinking water dataset into three major clusters, reflecting diverse sources of the physicochemical and bacteriological parameter: natural, agriculture and urban discharges.

This work assessed the groundwater hydrogeochemistry and the drinking water quality of 10 wells supplying the urban area of Zamora, Michoacán, Mexico. Two sampling campaigns were conducted in May 2018 (dry season) and November 2018 (wet season) to describe the chemistry of the water and its interaction with the rock. Physical and chemical constituents (temperature, pH, electrical conductivity, color, turbidity, solids, total hardness, total alkalinity, chemical and biochemical oxygen demands), major components (Ca2+, Mg2+, Na+, K+, SO42−, PO43−, HCO3−, CO32−, Cl−, N-NO3−, and N-NH3), as well as trace elements (As, Fe, Mn, Ba, Al, Sb, Co, V, Cu, Cd, Cr, Ni, Zn, Tl, Pb) were analyzed. Results showed groundwater with a slight tendency to alkalinity. The hydrogeochemical facies observed are Ca2+-HCO3− in all sites. Hydrochemical diagrams indicate immature, cold, non-saline, and uncontaminated water with short residence time. Water–rock interaction predominates. The water in the study area is appropriate for drinking use according to Mexican and international regulations with an excellent quality in 7 wells and good in the other 3.

Water quality deterioration has become an essential concern worldwide due to climatic ‎changes and increased pollution. As a result, the available drinking water supply resources‏ ‏will receive its ration of this deterioration. This study was conducted to monitor the water ‎quality of the Tigris River in eight different locations in Baghdad during the period ‎between 2005 and 2013. Water samples were collected and analyzed for fourteen ‎selected physicochemical parameters including alkalinity, total hardness (TH), turbidity, ‎total suspended solids (TSS), temperature, pH, nitrate, nitrite, phosphate, electrical ‎conductivity (EC), chloride, calcium, magnesium, and sulfate. To show the spatial and ‎temporal variations of the selected parameters along the study area easily and objectively, ‎Geographical Information System maps (GIS maps) were used. Results showed that the ‎obtained values in winter of alkalinity, turbidity, electrical conductivity, and the ‎concentration of calcium, magnesium, sulfate, nitrite, phosphate, chloride, and total ‎suspended solids were higher as compared with the corresponding values in summer. On ‎the other hand, temperature, total hardness, pH, and nitrate values were higher in summer ‎as compared with the corresponding values in winter. The water quality of Tigris River ‎throughout the study period was within the permissible limits of the Iraqi standards for ‎drinking water.‎

This study was conducted to assess the drinking water quality of north Mecha district, Amhara Region, Ethiopia. 26 drinking water samples were collected from the water points of the dweller community in the dry seasons of 2020 and subjected to the analysis of physicochemical parameters, bacteriological parameters, and the level of trace metals. The analysis of physicochemical parameters and the trace metals was carried out following the standard procedures of the laboratory, and the bacteriological water qualities were measured using the membrane filtration method. The F−, NO3−, SO42−, and Cu levels of the water samples were within the permissible limits of the WHO and compulsory Ethiopian standard (CES). Depending on turbidity, 61.54% of the tested water samples crossed the WHO limit of drinking water quality, and 100% of the samples surpassed the limits of EPA. Based on iron and ammonia levels, 38.46%, and 100% of the studied water samples violated the environmental protection agency (EPA) guidelines; 23.07%, and 3.84%, of the samples surpassed the WHO and CES drinking water quality standards. In view of pH, 23.07% of the tested water samples were not within the safe limit of the WHO and CES. 92.31% of the studied water samples were not potable as coliform bacterium (thermo tolerant indicator bacterium) growth was detected. The study revealed that the water sources of the study area are not safe for drinking unless appropriate treatment measurements are taken. Higher values of water quality parameters for the water samples from Koga irrigation site than the values for the water samples from the study sites found out of the irrigation site indicated the pollution load of Koga irrigation on the water quality of the area.

The present paper highlights the preliminary investigation of physico-chemical characteristics of tropical pilgrimage wetland viz. Dakor Sacred Wetland (DSW), Anand District, Central Gujarat, India. As the existing water body is contaminated with domestic sewage influenced by anthropogenic interventions, an urgent need was felt to evaluate physico-chemical parameters such as Temperature, pH, Dissolved Oxygen (DO), Total Solids (TS), Total Suspended Solids (TSS), Total Dissolved Solids (TDS), Free CO2, Phenolphthalein Alkalinity (PA), Total Alkalinity (TA), Carbonates, Bicarbonates, Total Hardness, Calcium Hardness, Magnesium Hardness, Chloride, Salinity, Sulphate, Phosphate, Nitrate, Sodium, and Potassium. The obtained data were correlated statistically to draw a conclusion about the surface water quality of tropical pilgrimage wetland. Moreover, the results manifested the need and prime necessity to restore the physical, chemical and biological integrity with viable and rigorous restoration and management strategies in order to maintain, preserve, conserve and to avert the ecological imbalance and disturbance in hydro-geo-chemical and hydro-biological cycles, which adversely affect the food chain and food web of the significant pond ecosystem.

Aim. Study of the influence of drinking water quality on the ecologically-dependent morbidity of the population of the Republic of Dagestan.Material and Methods. Methods of current and retrospective analysis of regional health indicators and methods of mathematical-statistical and medical-geographical analysis were used. Statistical processing of the results was carried out using the STATISTICA and Excel software packages. When carrying out laboratory studies on the quality of drinking water, we used a Lumex atomic absorption spectrometer "MGA-915MD".Results. Numerous hygiene studies indicate the direct impact of unsatisfactory drinking water quality on the health of a population. The relationship between sanitary and chemical indicators and the incidence rate for a number of nosological forms has been proven. It is generally accepted that human health is influenced by lifestyle factors (working, living and relaxation conditions), heredity and the ecological condition of the area of residence, including the quality of drinking water. Although it is not possible to differentiate the share of the negative effect caused by the consumption of poor quality drinking water but the incidence of certain nosological forms (cancer of the esophagus, gastrointestinal tract and kidney diseases) in the those regions of the Republic of Dagestan under consideration correlates with the characteristics of drinking water.Conclusion. The problem of pollution of water supply sources for the population in the dynamics of the long-term remains a priority concern. The quality and safety of drinking water are decreasing, which cannot but have a negative impact on public health. Correlation linkages between indicators of drinking water quality and oncological morbidity of the population were also established in indicators below the maximum permissible concentrations, which corresponds to a typical logistic model of causal relationships and serves as evidence of the high dependence of health disorders on chemical contamination of water supply sources.
