scholarly journals Results of quality studies of spring waters of the Republic of Tatarstan

Author(s):  

The study of springs is of great scientific and practical interest, because the population increasingly prefers to use spring water as an alternative source of drinking water. Methods. Studies were conducted to determine the water quality in 14 springs located on the territory of the Republic of Tatarstan, according to physical and chemical indicators in the summer period by organoleptic, potentiometric, titrimetric, photometric and gravimetric methods. Results. It was found that the water fully meets the hygienic requirements in only 8 springs (57.1 %). It was revealed that the non-compliance of spring waters with sanitary standards for physical and chemical parameters is associated with the excess of the MAC for nitrates and hardness. Also the excess of the MAC for total alkalinity was determined. The main reasons for the poor quality of drinking water are the pollution of water sources. The data obtained confirmed the need for constant monitoring of the water quality in all springs and development of measures to improve them.

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.

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.

A comprehensive study for the spatial distribution of drinking water quality had been conductedfor residential area of Lahore, Pakistan. The study had made use of the geographic information system(GIS) for geographical representation and spatial analysis of groundwater quality. Physicochemicalparameters including electric conductivity, pH, TDS, Cl, Mg, Ca, alkalinity and bicarbonates from 73 ofthe water samples had been included in the analysis. Water quality data had been geo-referenced followedby its interpolation using inverse distance weighted (IDW) for each of the parameters. Very high alkalinityand bicarbonates values were observed in most parts of the area. For the comprehensive view, water qualityindex map had been prepared using weighted overlay analysis (WOA). The water quality index map wasclassified into five zones of excellent, good, poor, very poor and unfit for drinking as per WHO standardsof drinking water. 21% region had excellent quality of the underground water and 50% was found goodfor drinking. Poor quality of water was found in southeastern part, covering 27% of the study area. Only2% of the area was found under the very poor and unfit water quality conditions for drinking.

This research aimed at assessing the drinking water quality of piped water distribution in Jimeta-Yola Adamawa State, Nigeria. The strategy was based on establishing the possibilities of contaminants underlying the distribution channels compromising the quality from the treatment source to the consumer point of use. Selected heavy metals and physiological parameters were determined toward establishing the water quality indices (WQI). Though, most of the parameter determined fell below or within the permissible limits (PL) set by WHO for drinking water, the results indicated significant (p<0.05) differences in the concentrations determined in the treatment plants (Yola treatment plant (YTP) and Jimeta treatment plant (JMTP)) with those at the consumer endpoints (YTPC and JMTPC). The results showed the WQI at the treatment plants being compromised due to the induction of pollutants across the distribution pipes. The water samples at the treatment point (JMTP) were excellent, having WQI <25 and good quality at YTP (25< WQI<50). However, the water quality on leaving the treatment source was observed to slightly change to poor quality at JMTPC (WQI= 57.00), and further observed to be in moderate-good quality at YTPC (WQI=49.27). Further analysis showed an increase in bacterial counts in the water samples at the consumer points.  Escherichia coli concentrations of 565 and 718 cfu /100 mL were detected in samples from YTPC and JMTPC, despite the fact the water was observed to be free from bacteria at the treatment plants.
