The exploitation of groundwater resources must always keep in account the geology and hydrogeological settings of the catchment basin for the sustainability of withdrawals, in order not to overexploit the aquifer. Especially, in the case of mineral water extraction, even more attention should be paid to understand what are the water-rock-gases interaction mechanisms, which allow obtaining a specific water chemistry. The case of Ferrarelle mineral water (western sector of Riardo Plain, Caserta) is particularly complex. Through the acquisition of a great amount of former geological and hydrogeological data and by new hydrogeological surveys, it has been possible to distinguish the aquifer levels, distinguishing four circulations over the Roccamonfina Volcano and in the Riardo Plain. The presence of volcanic and volcaniclastic deposits deriving from the Roccamonfina Volcano which cover a highlytectonized carbonate bedrock, allows the formation of two aquifers in hydraulic continuity. This mixing between the two aquifers allows, with the ascent of deep CO2 through faults in the carbonate bedrock, the formation of the typical chemical composition of the mineral water Ferrarelle. In the eastern sector of the plain, it is possible to distinguish the volcanic aquifer from the carbonate one, probably due to the presence of low permeability deposits.

Two kinds of bottled mineral water from wells located in the northern (Baeksansu, BSS) and southern (Baekdusansu, BDS) areas near Mt. Baekdu (Changbai) were collected in order to monitor the chemical compositions of the groundwater near a potential volcanic area. The bottled water was produced between August 2014 and June 2017, and corresponds to the Na-HCO3 water type. The trend in variation of each chemical component between the two bottled waters was different. The BDS bottled water from the southern area of Mt. Baekdu showed a dramatic change in chemical composition during the study period, whereas the BSS bottled water from the northern area did not show any significant change in chemical composition. In particular, the BDS bottled water showed either systematic increases or decreases of chemical components relative to the Cl concentrations. However, the BSS bottled water did not show such trends. It was confirmed that the chemical composition in the groundwater was constant, even though the monitoring period lasted for about two years. Our data indicate that it may be possible to use the chemical composition of the bottle water produced from the groundwater in the volcanic area as a proxy for monitoring the geochemical environmental change of the groundwater aquifer.

AbstractThe objective of this study conducted from October to December 2020 in the Natural Resources and Sensitive Environment Development Laboratory was to demonstrate the importance of conservation protocols respect throw evolution of water chemistry. Ninety-nine samples representing three water types (tap, spring and mineral water) were analyzed. Storage was at laboratory temperature with no conservation protocol. Studied parameters (temperature, pH, CE, dissolved oxygen, oxydo-reduction potential, total dissolved solids, HCO3−, Ca2+, Mg2+, SO42− and Cl−) were determined using standard methods. The data registered from physico-chemical parameters were subjected to different analytical methods to assess the time affect on their values compared with initial state. The results indicate that pH and alkalinity (exprimed in HCO3−) are the most vulnerable to evolution processes with highly significant time factor effect, while the concentrations of chlorides and sulfates with conductivity levels are statistically less evolved. PCA analysis accounting 71.43% of the total variance examines contribution of water type composition as a second variation factor. Projection through F1*F2 plan demonstrates clearly two groups with surface waters (tap water) which are excessively mineralized and groundwaters (spring and bottled waters) in which pH and magnesium parameters variations are the best illustrated.

One of the hydrogeochemical parameters that classify groundwater as mineral water is the content of fluoride ions. Their concentration is both important and limited for bottled mineral waters. Hydrochemical research of mineral waters in the surrounding area of Bukulja and Brajkovac pluton, in central Serbia, was conducted in order to define the chemical composition and genesis of these waters. They are carbonated waters, with content of fluoride ranging from 0.2 up to 6.6 mg/L. Since hydrochemical analyses showed variations in the major water chemistry, it was obvious that, apart from hydrochemical research, some explorations of the structure of the regional terrain would be inevitable. For these purposes, some additional geological research was performed, creating an adequate basis for the interpretation of the genesis of these carbonated mineral waters. The results confirmed the significance of the application of hydrochemical methods in the research of mineral waters. The work tended to emphasize that ?technological treatment? for decreasing the concentration of fluoride in mineral waters occurs in nature, indicating the existence of natural defluoridization.

The Dzhida ore field in the Zakamensk district of Buryatia features high concentration of mineralization within a small area. The Dzhida deposit is composed of complex ore. The ore field contains commercial-value primary deposits: Pervomai stockwork of molybdenum, Kholtoson tungsten lode and Inkur stockwork of tungsten. The Modonkul river catchment basin lies inside the Dzhida ore field. A real threat to the town of Zakamensk is created by manmade sand-bulk (old) tailings and slurry dump. By now, the concentrated flow of natural and man-made sand enters the low terrace and floodplain of the Modonkul river in the form of a talus train. This study is focused on the influence of the mine drainage effluent and the Inkur tributary on the water chemistry in the Modonkul river. 80 water samples were taken from the surface layer 0-0.5 m thick at five stations. Physicochemical indices of water were measured at the water sampling points, and the water chemistry was analyzed in a laboratory. In the background conditions, cations and anions in the Modonkul water chemistry range in decreasing order as follows: Са2+ > Mg2+ > Na++К+ и HCO - > SO 2- > Cl-. In the zone of mixture of natural and mine process water, the chemistry changes: from hydrocarbonate to sulfate (anion), from calcium-magnesium to sodium-calcium (cation). Downstream the natural chemistry changes to the hydrocabonate-sulfate composition, with prevailing content of calcium in cations. Iron content of water lowers 3-4 times after influx of mine effluents, while the contents of Mn, Zn, Co and Cd grow and then decrease downstream.

With abundant groundwater resources and obvious spatial distribution characteristics of confined aquifers, the Yuyao River valley is located in Ningbo, a coastal city in eastern China. It is greatly significant for studying the formation, movement and recharge of groundwater and establishing a sustainable groundwater management system to determine the spatial distribution of confined aquifers. In this paper, the spatial distribution of confined aquifers in the Yuyao River valley are studied by combining the symmetrical quadrupole electrical sounding method with hydrogeological data. Through analysis of the existing hydrogeological data, it is corroborated that there are sand gravel and round gravel confined aquifers in the study area. Then, the results of borehole-side electrical sounding measurements show that significant electrical differences are found among each rock-soil layer in the study area, and the resistivity of sand gravel and round gravel confined aquifers varies from 10 to 20 Ω·m. Finally, 77 symmetrical quadrupole electrical soundings on 5 lines were carried out perpendicular to the Yuyao River valley, and the data of electrical sounding were inverted and analyzed by the analysis software of GeoElectro. After calibration with boreholes, the confined aquifers in the study area were determined to be zonally distributed along the middle line of the valley, with buried depth ranging from -65 to -25 m and width exceeding 1000 m.

We tested the effect of various culture media on life-history traits in three clones of the rotifer Lecane inermis, a potential bulking control agent. Four types of media were tested: a filtrate of activated sludge, mineral water, and each of these media enriched with molasses. The number of live and dead individuals and the number of amictic eggs were counted during the 14-day experiment, and the egg ratio (ER) and mortality rate were calculated. We found that the rotifers were well adapted to the changes in chemical composition of the medium and that the addition of molasses resulted in a significant increase in rotifer abundance. The highest ER was noted after two days, reaching a maximum of 4 eggs per female in treatments with filtrate and molassesenriched filtrate. The life-history traits varied depending on the clone and the medium, but all of the clones were able to survive and proliferate, even after 14 days of starvation.

The quantity and quality of water resources determines sustainable development of any country, as well as the standard of living and the health of the population. According to the national water cadastre, in 2009, 2.35 million m3 of water per day was taken from 20 thousand production wells in Belarus. The Republic of Belarus has significant mineral water resources, and there are 224 wells with mineral water on its territory. There are 130 wells in operation, and 94 wells are reserve wells. Drinking water supply in the Republic of Belarus is mostly based on the use of underground sources, with the exception of the cities of Minsk and Gomel, which makes it possible to obtain better and cleaner water than water from surface sources. At the same time, a significant part of wells operate at lower rate due to the phenomena of mechanical, biological and chemical clogging. Chemical clogging is an unavoidable process. Even with high-quality drilling operations, during well operation, due to the appearance of hydrodynamic disturbances in the reservoir, the gas equilibrium in underground water is shifted, which results in precipitation of hard-to-dissolve iron, calcium, manganese, and silicon compounds on the filter and in the filter zone. The analysis of the service life of water intake wells has shown that the main causes of their failure are filter clogging and sanding. The service life of most wells, even if mudding sediments are removed by the known methods, is never longer than 16–20 years. Operation of inefficient wells, their subsequent abandonment and re-drilling require significant financial resources. Currently, outdated wells are being designed and constructed at water intakes in the Republic of Belarus. They are insufficiently maintainable and short-lived, have a significant cost and high operating costs for lifting water. One of the ways to solve the problem is to build wells with annular systems of circulating reagent regeneration and replaceable filters to provide a significant increase in resource, stability of flow rate and reduction in operating costs. This will allow us to modernize water intakes of underground water by switching to wells of new designs and to reach a better level in ground water production.
