Abstract:

The aim of this work was to study the occurrence of Aeromonas sp in the bottled mineral water, well water and tap water from the municipal supplies. Positive samples were found for Aeromonas spp. 12.7% from the mineral water, 8.3% from the artesian water and 6.5% from the tap water. The recovery of Aeromonas spp. was significantly higher in the bottled mineral and artesian water than in the tap water from municipal supplies. The occurrence of the Aeromonas spp. did not correlate significantly with the contamination indicator bacteria (i.e. total coliforms) in the artesian water samples. However, a significant correlation was found between Aeromonas spp. and total coliforms in the both mineral water and tap water samples. The presence or absence of a correlation between the indicator bacteria and Aeromonas could reflect the occasional appearance of the pathogen in the drinking water and the different rates of survival and recovery of these agents compared with those fecal indicators. The finding that 41.6, 14.8 and 9.0 % of the artesian water, bottled mineral water and tap water, respectively, sampled in the current study failed to meet the Brazilian standard for total coliforms in the drinking water should therefore be of concern.

Abstract:

Following the recent discovery of artesian supplies, the Shearers’ Strike of 1891 and the onset of the Federation drought (1895–1902), A. B. ‘Banjo’ Paterson’s Song of the Artesian Water, published in 1896, was written at a time of profound social and environmental upheaval in the ‘bush’ of Australia. In order to better understand the historical encounters between colonial capitalism and semiarid rangeland environments, this paper unpacks the cultural meaning behind Song of the Artesian Water by exploring the interactions between water, scientific knowledge, drought and environmental transformation along the pastoral frontier of Queensland. Banjo Paterson’s poem is used as a framework to provide an historical interpretation of European exploitation of the Great Artesian Basin as well as a framework for current economic uses and environmental threats.

Abstract:

Inquiries into the diminishing supply of artesian water within the Queensland aspect of the Great Artesian Basin began in 1939. These investigations produced a Queensland phenomenon without Australian precedent in terms of rationale, geographical diversity, and commitment of resources. In some regions, exposure of herds to fluoride emerged as an urgent issue because fluoride was perceived as an invasive, invisible, and odourless 'contaminant' in artesian water. This paper discusses the scientific background to, and management of, concerns over the consumption by stock of artesian water with a high concentration of natural bioavailable fluoride. The Queensland Department of Agriculture and Stock managed the problem by scientific investigation, methodical field study, and the application of research findings to animal husbandry. The practical solutions arrived at involved rotation of stock on an age-related basis to and from certain bore supplies, fencing young sheep away from the artesian supply, fencing young sheep near the bore-head, and limiting the use of supplements.

Abstract:

The Mukhrani artesian basin is a reservoir containing high quality groundwater. Well-known aquifers and galleries are located within the artesian basin, which are one of the main sources of drinking and household water supply for the city of Tbilisi. The article summarizes the hydrogeological conditions of the Mukhrani artesian basin. The hydrogeological parameters of the productive aquifer were determined based on the results of studies carried out at the existing water intakes. A hydrodynamic map of the artesian basin was compiled. The spatial and quantitative distribution of groundwater resources in the basin has been estimated.

Abstract:

Abstract. Understanding pathways of recharge to alluvial aquifers is important for maintaining sustainable access to groundwater resources. Water balance modelling is often used to proportion recharge components and guide sustainable groundwater allocations. However, it is not common practice to use hydrochemical evidence to inform and constrain these models. Here we compare geochemical versus water balance model estimates of artesian discharge into an alluvial aquifer, and demonstrate why multi-tracer geochemical analyses should be used as a critical component of water budget assessments. We selected a site in Australia where the Great Artesian Basin (GAB), the largest artesian basin in the world, discharges into the Lower Namoi Alluvium (LNA), an extensively modelled aquifer, to convey the utility of our approach. Water stable isotopes (δ18O and δ2H) and the concentrations of Na+ and HCO3− suggest a continuum of mixing in the alluvial aquifer between the GAB (artesian component) and surface recharge, whilst isotopic tracers (3H, 14C, and 36Cl) indicate that the alluvial groundwater is a mixture of groundwaters with residence times of < 70 years and groundwater that is potentially hundreds of thousands of years old, which is consistent with that of the GAB. In addition, Cl− concentrations provide a means to calculate a percentage estimate of the artesian contribution to the alluvial groundwater. In some locations, an artesian contribution of up to 70 % is evident from the geochemical analyses, a finding that contrasts with previous regional-scale water balance modelling estimates that attributed 22 % of all inflow for the corresponding zone within the LNA to GAB discharge. Our results show that hydrochemical investigations need to be undertaken as part of developing the conceptual framework of a catchment water balance model, as they can improve our understanding of recharge pathways and better constrain artesian discharge to an alluvial aquifer.

Abstract:

SUMMARY The aim of this work was to compare, from a parasitological ( Cryptosporidiumspp. and Giardia duodenalis), bacteriological (total and thermotolerants coliforms) and physicochemical perspective, water sources used for drinking and irrigation of vegetables intended to be sold for human consumption. From January 2010 to May 2011, samples of different water sources from vegetable producing properties were collected; 100 liters for parasitological analysis, 200 mL for bacteriological analysis, and five liters for physicochemical analysis. Water samples were filtered under vacuum with a kit containing a cellulose acetate membrane filter, 1.2 µm (Millipore(r), Barueri, SP, Brazil). The material retained on the membrane was mechanically extracted and analyzed by direct immunofluorescence (Merifluor(r)kit). From 20 rural properties investigated, 10 had artesian wells (40 samples), 10 had common wells (40 samples), and one had a mine (four samples), the latter contaminated by Cryptosporidiumspp. In samples from artesian wells, 90 to 130 meters depth, 42.5% were positive for total coliforms and 5.0% were identified to have abnormal coloration. From the samples of common wells, 14 to 37 meters depth, 87.5% were contaminated with total coliforms, 82.5% were positive for thermotolerant coliforms, and 12.5% had color abnormalities. We did not detect the presence of Giardiaspp. or Cryptosporidiumspp. in artesian and common wells. The use of artesian or common wells is an important step in the control of the spreading of zoonoses, particularly Cryptosporidiumspp. and Giardiaspp., as well as artesian wells for coliform control in local production of vegetables to be marketed.

Abstract:

The article focuses on the features of the formation of artesian basins of intermountain type. The conditions of formation of groundwater of Heihe artesian intermountain basin, located in the arid region of North-Western China, and water resources of the Tien Shan within Kyrgyzstan are considered. The differences in the hydrogeological structure of the basins, the features of recharge / discharge caused them to be divided into areas that are characterized by features in the chemical composition and quality of groundwater. This study describes the factors affecting the formation of groundwater, the geological and hydrogeological, and also hydrodynamic features of intermountain artesian basins. The main pattem of groundwater flows is characterized and the conceptual models of groundwater systems are presented. The chemical composition of their constituent aquifers is characterized. The obtained results provide a scientific basis for rational planning of social-economic management in the water-limited regions.

Abstract:

The urgency of the conducted studies is dictated by the problem of Urban Territories’ sub-surface waters purification providing in the Republic of Sakha (Yakutia) population with drinking water, which can be partly solved by involving the sub-surface waters of the Yakutian artesian basin in the domestic and drinking water supply systems. The chemical composition feature of the under-ground waters under consideration, which substantially complicates their widespread use for domestic and drinking purposes, is the increased content of lithium, fluorine and sodium. The main research objective is to develop an effective method for clearing the sub-permafrost waters of the Yakutian artesian basin from lithium compounds, which can be used in water treatment systems for domestic and drinking purposes. As a result of the experimental studies on the sub-permafrost water purification of casting by the ion exchange method, its content reduced from 0.5 to 0.01 mg / l, which fully met the requirements for drinking water. On the basis of the results obtained, a comprehensive scheme for the sub-permafrost waters purification of the Yakutian artesian basin from lithium, fluorine and sodium was developed for the purpose of household and drinking water supply.

The article contains a description of the hydrodynamic features of the Mukhran artesian basin and a generalization of the hydrogeological conditions. Based on the results of experimental filtration studies carried out in the wells of existing water intakes, the hydrodynamic parameters of pressure aquifers were determined, according to which a map of the permeability of aquifers of the Quaternary period was compiled. The peculiarities of changes in water conductivity indicators formed the basis of isolated hydrodynamic zones, which is a clear expression of the filtration structure of the Mukhran artesian basin, in terms of the distribution of pressurized groundwater resources.

The formation of water-deficit conditions in most of the territory of the Crimean Peninsula causes the redistribution of surface and underground runoff between regions. Available volumes of water resources in various regions of the Crimea are distributed unevenly, which requires the construction of long water supply routes. To improve water supply, a water supply System has been developed for the Eastern Crimea with artesian water from wells in the South-Eastern part of the Crimean Peninsula.

Abstract:

The paper aims to investigate hydrodynamic treatment processes of raw (artesian) groundwater to be used for household needs and drinking. The main advantage of hydrodynamic raw water treatment is that a single device, a so-called hydrodynamic vibration generator, is enough to perform the most important processing (deferrization, manganese removal, aeration) without any additional reactants. A hydrodynamic vibration generator contributes to accelerating mass exchange processes without using additional chemical reactants, solely by means of the kinetic energy inherent in the raw water flow undergoing treatment, which is generated when the hydrodynamic properties of the flow itself change dramatically. The generator by itself does not purify water; it processes raw water so as to derive insoluble products by recombining the forms in which the substances to be removed are found in the water, that is, by transforming dissolved manganese and iron compounds into insoluble compounds and decreasing carbon dioxide content in the water so as to precipitate insoluble calcium compounds. The resulting insoluble compounds are easy to remove via further processing in a ceramic membrane filtration system. Hydrodynamic vibration generator efficiency depends on many factors, which means that, when implementing hydrodynamic raw water treatment in real life, obtaining fundamental laws governing the treatment processes as functions of respective parametric characteristics is a necessary stage so as to ensure maximum efficiency. Our experiment confirmed that a phenomenon known as sonoluminescence occurs in raw water subjected to hydrodynamic treatment. We propose a monitoring technology indirectly confirming the efficiency of the hydrodynamic raw water treatment implemented, which is based on recording the sonoluminescence phenomenon via an acoustic technique

Abstract:

The problem of clean water supply to meet the needs of the community is the main obstacle experienced by residents of Bumi Purnawira housing. Water management is completely left to the residents starting from installation of pipes to each house, installation of water meters, calculation of the cost of water usage per cubic meter, as well as administration and maintenance of the artesian well. Some problem that arise include: frequent miscalculation of cost to be paid; monthly meter recapitulation records in the form of paper prone to damage and data lost; meter recapitulation records is only kept by the treasurer, so if the residents want to know the history of meter records and the payment, they have to see the treasurer; the meter’s monthly status is vulnerable to manipulation whether done by the residents or the treasurer; There is often a discrepancy between the financial recapitulation recorded and the physical cash; and financial expenditures are sometimes not properly recorded, so that it triggers the discrepancy between the recorded amount and the physical cash. Seeing the existing reality, an idea to make an application for the management of artesian well administration has arisen. The initial step is to form two teams, namely the development team and the socialization team. The development team is responsible for developing the management system of the artesian well’s administration and finance. Meanwhile, the socialization team is responsible for conducting the socialization and the application training. The result of this project is an application and socialization that can help both the administrators and the residents in managing the administration and finance of the artesian well.

Abstract:

Various studies have shown that stable isotope analysis has the potential to verify the geographic origin of foods and drinks. However, stable isotope composition is not always constant in the environment and can even change in the same area. Dairy products are of particular interest as a group of foods that play an important role in feeding the population. The composition of milk is fundamentally dependent on the feeding of the cows, and thereby on a particular environment. To better understand the amount of variation in δ18O, δ13C, and δ15N values in the milk from the same area, we measured stable isotope ratios in cow milk water, artesian water, and precipitation (δ18O) as well as in bulk milk samples (δ13C and δ15N) collected in 2014–2016. Different water and food sources were available during the winter (artesian water only and dry grass) and summer (artesian water and fresh grass), and spring and autumn seasons reflected transitional periods. Oxygen stable isotope ratios in milk water were relatively lower in winter and transitional seasons and higher in summer, showing the dependence on the main water source. δ13C values reflected particular food sources. This study shows the applicability of the stable isotope ratio method in linking cow milk to specific environments and reveals the amount of variation in stable isotope ratios in the same area. These results could be valuable for other studies on geographical origin determination of dairy products.

Abstract:

Culture and molecular methods were used to describe the planktonic bacterial diversity of an artesian water supply in rural Latah County, Idaho, within the drainage of a small perennial stream, Thorn Creek. The surrounding depth to groundwater at this location is thought to be significant (>100 m), and this transitional zone (basalt–granite) of the Palouse aquifer system is little studied. The water produced by this artesian source is consistent even in years of drought and is of high quality, both mineralogically and microbiologically. A culture-based analysis using 30 media types and four incubation temperatures demonstrated that several metabolic types were present in the water. 16S rRNA gene fragments amplified from the DNA of pooled cultured cells and from the DNA extracted from 1 L of the source water were compared using denaturing gradient gel electrophoresis. The results indicated that the two DNA samples did not have similar 16S rRNA gene compositions and that several uncultured phyla were present in the community DNA sample. These results indicated that large-scale culturing did not accurately represent the structure planktonic community. 16S rRNA gene sequences from 17 different genera were obtained from the community DNA sample; the most abundant were similar to Rhodoferax, Rhodobacter, and Polaromonas species. Sequences related to the Proteo bacteria, Bacteroidetes/Chlorobi, Firmicutes, and Acidobacterium/Fibrobacter divisions were also detected.Key words: artesian spring, bacterial diversity, DGGE, 16S rRNA, enrichment culture.

Abstract:

Production landscapes depend on, but also affect, ecosystem services. In the Rejoso watershed (East Java, Indonesia), uncontrolled groundwater use for paddies reduces flow of lowland pressure-driven artesian springs that supply drinking water to urban stakeholders. Analysis of the water balance suggested that the decline by about 30% in spring discharge in the past decades is attributed for 47 and 53%, respectively, to upland degradation and lowland groundwater abstraction. Consequently, current spring restoration efforts support upland agroforestry development while aiming to reduce lowland groundwater wasting. To clarify spatial and social targeting of lowland interventions five clusters (replicable patterns) of lowland paddy farming were distinguished from spatial data on, among other factors, reliance on river versus artesian wells delivering groundwater, use of crop rotation, rice yield, fertiliser rates and intensity of rodent control. A survey of farming households (461 respondents), complemented and verified through in-depth interviews and group discussions, identified opportunities for interventions and associated risks. Changes in artesian well design, allowing outflow control, can support water-saving, sustainable paddy cultivation methods. With rodents as a major yield-reducing factor, solutions likely depend on more synchronized planting calendars and thus on collective action for effectiveness at scale. Interventions based on this design are currently tested.

Abstract:

There has been investigated the chemical composition of groundwater from a series of wells from Causeni district, Republic of Moldova. Using the Water Quality Index (WQI), the quality of the analyzed water has been classified. It was emphasized that the water from artesian wells does not meet the state standards for the drinking water. The quality indexes – the content of ammonia and ammonium ions, hydrogen sulfide and soluble sulfides, as well as the content of sodium and fluorine ions. exceed the maximum permissible concentrations (MPC), while the total hardness is under the MPC parameters. In groundwaters, the exceeding of the maximum permitted concentrations for the content of nitrates, nitrites, ammonium ions, calcium and magnesium salts, sodium ions, sulphates, etc. was registered most frequently. Using the WQI method, it was shown that none of the analyzed water samples from artesian wells were classified as “excellent” or “good”. Only two water samples from wells entered the ”good” category

Abstract:

The article presents the results of in-situ studies of the chemical composition and quality of underground (subsoil and artesian) water within the basin of the Baraboy River where irrigation of agricultural areas using the water resources of the Dniester River has been carried out since 1967. These water resources are fed into the network of reservoirs and channels of the Lower Dniester Irrigation System. Filtration losses of water from irrigation areas and water supply and sewage systems of settlements replenish the reserves of underground (subsoil) waters increasing the ingress therein of dissolved substances from the sedimentary rocks which leads to increase in the concentrations of certain ingredients included in chemical composition of surface and underground waters within the basin of the Baraboy River. It is shown that groundwater is enriched with nitro-gen compounds containing high concentrations of chlorides, sulfates, calcium and magnesium. Mineralization, toxicity and degree of contamination of underground water increase along the length of the Baraboy River. The chemical composition of the groundwater coming to the riverbed of the Baraboy River does not meet the fishing requirements and worsen the water quality of fish farming water bodies. The results of assessment of groundwater quality at the stations under study give reason to consider these sources of groundwater as an important factor affecting the hydrochemical regime and the quality of the water of the Baraboy River and its reservoirs which should be taken into account when developing the recommendations for optimization of the current hydroecological state of the Baraboy River as a whole. If high mineralization and significant content of principle ions in groundwater can be explained by natural factors, the high level of contamination by biogenic substances is resulted from entering of industrial, domestic and return waters from irrigated areas into aquifers. Such contamination is not a temporary but a permanent phenomenon. In terms of magnesium content artesian waters used for utility and drinking water supply are recognized as «mediocre, suitable with limitations and having undesirable quality». In addition, after 50 years of operation compounds of nitrogen and phosphorus were found in artesian water, and this was not a case in 1960s of the last century. A conclusion on the negative effect of long-term donor irrigation on the quality of underground water and on the need for additional treatment of water of artesian aquifers of the Sarmatian Stage used for centralized water supply was made.

Abstract:

The creation of effective demanganization technologies by the development of new and intensification of known processes of manganese removal from natural waters are currently of increasing importance.The search for promising ways to demanganize water to regulatory values is a topical issue for the modern water treatment domain.Recent publications of methods for extraction of manganese ions from water by sorption, membrane, ion exchange methods were reviewed. The prospects of application of oxidative methods for water demanganation are shown.The purpose of the article is to investigate the manganese ions removal methods from water during their oxidation by sodium hypochlorite and to establish the dependence of the efficiency of demanganization on the consumption of oxidizing agent and the concentration of manganese ions in water.The study presents the application of sodium hypochlorite as an oxidant in the purification of artesian water from manganese ions. It was determined in static conditions that the degree of manganese removal is affected by both its initial concentration in water and the dose of sodium hypochlorite. Water purification process is more efficient with initial manganese concentrations above 5 mg/dm3. At a manganese ion concentration 30 mg/dm3, its complete removal was achieved in 4 hours of settling at a stoichiometric ratio of manganese and sodium hypochlorite in water and at any excess of oxidant. The process of manganese ions oxidation in artesian water by sodium hypochlorite depending on its dose and contact time was studied. The dose of oxidant for the removal of manganese ions from artesian water was also determined. Thus, the research allowed to improve the methods of water purification from manganese ions during their oxidation by sodium hypochlorite and found that the water purification efficiency increased both with increasing consumption of oxidizing agent and increasing the concentration of manganese ions in water.

Abstract:

A controlled study was conducted in Lebanon over a period of 12 months to determine bacterial regrowth in a small network supplying the Beirut suburb of Naccache that had a population of about 3,000. The residential area, which is fed by gravity, is supplied twice a week with chlorinated water from two artesian wells of a confined aquifer. A significant correlation was detected between the turbidity and the levels of heterotrophic plate count bacteria (HPC) in the samples from the distribution network as well as from the artesian wells. However, a negative significant correlation was found between the temperature and the HPC count in the samples collected from the source. A statistically significant increase in counts, possibly due to regrowth, was repeatedly established between two sampling points lying on a straight distribution line but 1 km apart. Faecal coliforms were detected in the source water but none in the network except during a pipe breakage incident with confirmed Escherichia coli reaching 40 CFU/100 mL. However, coliforms such as Citrobacter freundii, Enterobacter agglomerans, E. cloacae and E. skazakii were repeatedly isolated from the network, mainly due to inadequate chlorination. A second controlled study was conducted to determine the effect of storage on the microbial quality of household storage tanks (500 L), which were of two main types - galvanized cast iron and black polyethylene. The mean bacterial count increased significantly after 7 d storage in both tank types. A significant difference was found in the mean HPC/mL between the winter and the summer. Highest counts were found April-June although the maximum temperature was reported later in the summer. A positive correlation was established between the HPC/mL and pH, temperature and storage time.

Abstract:

ABSTRACT Pumpkin (Curcubita moschata Duchesne) production in quantity and quality is often restricted due to adverse environmental conditions. Thus, the objective was to evaluate the action of phytohormones as stress attenuators on the germination and initial growth of pumpkin seedlings, cv. Sergipana, under different types of water. The design adopted was completely randomized, in a 3 × 4 factorial scheme, with four repetitions. In addition to the control, the seeds were treated with the gibberellic and salicylic acids and irrigated with the supply water, fish farming wastewater, artesian well water and solution of the mixture of fish farming wastewater + artesian well water, in a 1:1 ratio. The variables evaluated were germination, first germination count, germination speed index, length of shoots and roots, dry mass of shoots and roots, soluble sugars, amino acids and proline. Treatment of pumpkin seeds, cv. Sergipana, with gibberellic and salicylic acids improved germination kinetics and attenuated the effects of water salinity during the initial growth of pumpkin seedlings.

Abstract:

A traffic causeway placed on the sediments of saline Tramping Lake failed during construction in the summer of 1982. Vertical subsidence has continued until present (1988). The failure mechanism was controlled by sedimentary structure and artesian groundwater conditions. The shear zone is in a soft, near normally consolidated lacustrine sandy silt unit 22 m thick. The lake basin contains lacustrine, deltaic, and fluvial deposits of postglacial origin. Artesian conditions in the Upper Cretaceous Judith River Formation and postglacial fluvial sand and gravel dominate the hydrogeology at the site. The failure took place along a composite slip surface when excess pore-water pressures developed during loading [Formula: see text]. The estimated effective friction angle from triaxial tests and back calculation was 27° assuming c′ = 0. However, a parametric analysis showed that at very high pore-water pressures the effective friction angle required for equilibrium is very sensitive to small variations in ru. The calculated cohesion at [Formula: see text] required for equilibrium was 3.9 kPa, whereas the remolded vane strength measured in the field was 5.0 kPa. Key words: Foundation failure, artesian, saline environment, groundwater discharge, silty clays, postglacial fluvial and lacustrine deposits.

Abstract:

Artesian wells remain strategically important sources of drinking water for the Kyiv megacity, especially in the vicinity of radioactively contaminated areas of the Chornobyl exclusion zone. The contribution of groundwater to the total volume of drinking water was indicated. The water from 144 artesian wells was investigated in terms of total alpha activity: 67 of them were drilled up to the Cenomanian aquifer of the Upper Cretaceous, 77 - up to the Bajocian aquifer of the Middle Jurassic. Studies have found that the total alpha activity in 39 wells exceeds the regulatory limit, with 37 of the 39 wells supplying water from the Bajocian aquifer. The average total alpha activity of the Cenomanian water is 0.033 ± 0.003 Bq/dm3, the most active water of this aquifer is produced in the Obolon area where the average value equals 0.045 ± 0.004 Bq/dm3. The average total alpha activity of the Bajocian water is 0.115 ± 0.012 Bq/dm3, the most active water of this aquifer is produced in the Obolon and Troyeshchyna areas where the average values equal 0.097 ± 0.010 Bq/dm3 and 0.188 ± 0.018 Bq/dm3, respectively. Therefore, in average, the Bajoian water is 3.5 times more active than the Cenomanian one: the average activity reaches 0.115 ± 0.012 Bq/dm3 against 0.033 ± 0.003 Bq/dm3. GIS mapping of the total content of α-emitters in the groundwater of both aquifers was created. The dynamics of the gross alpha activity of artesian water from both aquifers was monitored for the Obolon area. It was determined that when consuming the Bajocian water, two times more alpha-emitters enter the human body than from the Cenomanian water. The processing of the results through the spline interpolation with the Spatial Analyst Tools module ArcGIS 10.1 made it possible to analyze this trend for the megacity area: geological and tectonic factors such as block movement of the foundation, unequal incision of ancient watercourses into the pre-Bajocian surface and the erosion of sediments had always had the greatest influence on the enhanced alpha activity of the Bajocian water.

AbstractThe MH-2B borehole, a part of Project HOTSPOT, was drilled to a depth of 1821 m in late Cenozoic basalts, hyaloclastites and interbedded lake sediments, on the Mountain Home Air Force Base in southern Idaho, USA. Drillers encountered hot water (145°C) under artesian pressure at 1745 m in a narrow zone of highly fractured rock associated with a major sub-surface fault. X-ray diffraction (XRD) analysis identified corrensite (with and without smectite) between 1700 and 1800 m, but only smectite above 1700 m and below 1800 m. This corrensite horizon contains a relatively narrow zone of fracturing and hot artesian water near its centre but for the most part occurs in relatively massive basalt flows. No evidence was found for randomly interstratified chlorite-smectite.

Full text

Abstract:

The Great Artesian Basin (GAB) underlies a vast, mainly arid, region where most of the indigenous biota are not dependent upon surface water. In contrast, an important minority is dependent on refuges such as mound springs and their associated wetlands. In some parts of the GAB, such as western New South Wales, many springs have either ceased to flow, or are now barely detectable, because the proliferation of artesian waterbores has reduced groundwater pressures. Because of the rarity of species endemic to mound springs, and the damage they have suffered since pastoral settlement, emphasis should be directed towards conservation and possible rejuvenation of these ecosystems. Provision of artificial sources of water allows more widespread grazing by livestock, larger native and feral herbivores, thereby posing threats to native plants and animals that do not use the water. Because of the proliferation of artificial waters and the grazing they allow, terrestrial grazing-sensitive species now appear to be confined to tiny patches in the landscape. Some nature reserves within the GAB retain numerous artificial sources of water. Most of these should be closed over time to reduce negative impacts on grazing-sensitive plants and animals, especially where these species are inadequately protected elsewhere. In those regions where the ratio of artificial to natural waters is still low, consideration should be given to balancing provision of water for livestock with conservation of biological diversity, by maintaining a patchwork of areas remote from water. In regions where the density of artificial waters is high, conservation of biodiversity on freehold and leasehold lands might be enhanced with a mix of approaches accommodating the needs of the biota and the aspirations of landholders, tailored according to land type and condition. Key words: Great Artesian Basin, biological diversity, mound springs, refuges, rare biota, grazing impact, conservation management, groundwater.

Abstract:

More than 200 million people worldwide are exposed to excessive fluoride in drinking water. According to the World Health Organization, the optimal concentration range of fluoride in drinking water is 0.5 to 1.5 mg/L. Above this range, populations may contract dental fluorosis or, in severe cases, crippling skeletal fluorosis. In the Gokwe area in NW Zimbabwe, where drinking water contains up to 11 mg/L fluoride, fluorosis prevalence has previously been estimated at 62%. This paper investigates the water quality of 126 water sources in Gokwe (58 pumped boreholes, 15 flowing artesian boreholes, 46 wells and 7 streams). The water chemistry, determined from high performance ion chromatography and field measurements, showed that the water source types exhibit significantly different (P < 0.05) concentrations of F−, Cl−, Na+, K+, Ca2+, Mg2+, temperatures, pH and conductivity values. Thirty-five (28%) of the 126 water sources (18 pumped boreholes, 15 artesian boreholes, one well and one stream) contained F− > 1.5 mg/L, indicating that fluoride contamination in the area is a characteristic of deeper groundwater, possibly due to its interactions with the potentially fluoridic coaly and carbonaceous materials of the Lower Karoo Aquifer at depth. The plausibility of providing alternative low fluoride water, and defluoridation, should be investigated.

Introduction. Drinking water includes a multitude of natural elements, with a strong connection between them, which through the dynamics of their modification in many cases influence the health of the population. Material and methods. The quality of drinking water from the Prut river ecosystem was studied (water from aqueducts fed from the river, water from artesian wells, water from adjacent wells), health status of the population from riparian localities (Lipcani, Ungheni and Cahul). The correlations between these two indicators and the risk of population disease caused by water quality were calculated. Hygienic, epidemiological, sanitary-chemical and statistical methods of investigation were used. Results. Following the study, the existence of small and medium correlative dependencies between the water quality indices from the aqueduct fed from the Prut River and the prevalence of the main groups of nosology of morbidity was highlighted. High direct correlative dependencies of health indices on water quality in artesian wells and wells were quantified. The values of the risk of genito-urinary, osteo-articular, digestive system, blood diseases/anemia, etc. were determined. Conclusions. Finally, there was a causal relationship between the factors investigated and the health of the population, highlighting the risk of developing nosological forms.

Abstract:

Objective: We aimed to analyze the results of the measurements of the total alpha activity and activity of radon-222 in the water of artesian wells to establish the geographical regions of Ukraine which require a deep attention to the assessment of the radioactivity of the groundwater. Methods: We used empirical, analytical, radiometric, spectrometric methods and method of mathematical statistics in the study. Materials: We carried out a statistical analysis of the results of the measurements of the total alpha activity and the activity of radon-222 in water samples from the artesian wells of 23 administrative regions of Ukraine studied during 2016 - 2020. Results: Analysis of the results of the measurements of the total alpha-activity and radon-222 activity in the water of artesian wells showed their significant heterogeneity for different regions of Ukraine and a connection with the geological features of the area. The statistical distribution of the values of the total alpha activity and the activity of radon-222 in water samples, diagrams of the range of measured values within the regions of Ukraine and between regions are presented in the work; the measurement results were plotted on the hydrogeological map of Ukraine. Conclusion: The values of the total alpha activity and the activity of radon-222 indicate that these indicators are extremely heterogeneous for the territory of Ukraine and reflect the geological features of the area. The results of the analysis can be useful for making recommendations to collective and individual water consumers, well owners regarding the need in more detailed study of the content of natural radionuclides in the sources of water and the use of the appropriate methods of water treatment in cases of non-compliance with the accepted standards. It is shown that it is necessary to develop a strategy for radiation monitoring of the groundwater quality in the country in order to study objectively the existing state and the achievement of an acceptable quality of the water consumed by the population.

In order to investigate the pollution with hexavalent chromium (Cr6+) of the groundwater and surface water around the industrial dump Jugohrom – Jegunovce, hydrogeological investigations were carried out during November 2019, where 16 samples of groundwater and 3 samples of surface water were taken. In most of the analyzed samples of groundwater and surface water, the concentration of Cr6+ exceeds the maximal allowed concentrations (MAC) of Cr6+ (0.01 mg/l) according to the Macedonian and European standards in drinking water. The highest contamination with Cr6+ which is in the range of 0.052 – 132.98 mg/l is registered near the dump in the shallow groundwater, i.e. in the unconfined aquifers. Cr6+ pollution ranging from 0.017 to 0.041 mg/l has also been registered in some of the samples at artesian aquifers with a sub-artesian level. Two tests were carried out on the surface water of the Vardar River, before and after the dump. A sevenfold increase in Cr6+ concentration of 0.069 was observed after the dump. Cr6+ content of 725 mg/l was found in the drainage of overflow water in the discharge. Pollution of the groundwater and surface water with Cr6+ is anthropogenic and is a result of the operation of the Metallurgical Plant Jugohrom in the period from 1955 to 1994.

Abstract:

The uneven distribution of water resources in most of the Crimean Peninsula leads to the redistribution of surface and underground runoff between regions. The available volumes of water resources in the Nizhnegorsk District have been redistributed due to the construction of extended water supply routes and groundwater intakes. An assessment of the rationality of using artesian waters from wells in the Nizhnegorsk region of the Crimean peninsula is carried out.

Abstract:

Purpose: The popularity of bottled water products (BWPs) is growing in Canada. Concentrations of minerals with important implications for health were compared in different types of BWPs. Methods: One sample of each brand and type of plain BWP (purified, remineralized, spring, mineral, and artesian), flavoured BWP, and nutrient-enriched BWP sold in major stores in Ottawa, Ontario, was purchased to allow determination of mineral concentrations by flame atomic absorption or emission spectroscopy. A total of 124 BWPs representing 37 brands were analyzed. Results: In general, spring and mineral water contained higher amounts of magnesium and calcium than did purified, remineralized, artesian, flavoured, or nutrient-enriched water. Most plain BWPs contained little sodium and potassium, whereas 15% to 35% of flavoured and nutrient-enriched products had considerably higher concentrations. Only magnesium and calcium concentrations were highly correlated (r=0.76, p<0.001). Calculation of the percentage of Dietary Reference Intakes that could be supplied by each product revealed that, if they are consumed habitually, many products can contribute substantially to recommended intakes of these minerals. Conclusions: Mineral concentrations in most types of BWP varied, but distinct differences between types of products were identified. Consumers should be aware of the mineral content of BWPs because some could influence intakes of certain minerals significantly.

Abstract:

Abstract The article presents the results of a study on the geochemistry of fresh water from natural sources (springs) in the salt dome territories of the Pre-Ural Artesian Basin. Spring waters are understudied; they are not classified according to their chemical composition and purpose. The research area is the territory of the Pre-Ural Artesian Basin in Orenburg Region with salt-gypsum tectonics. There are numerous springs with fresh water suitable for household and drinking purposes there. Springs with mineralization from 156 to 806 mg/dm3 of mixed composition, sulfate-chloride, sulfate-bicarbonate, bicarbonate and calcium and magnesium-calcium, sodium-magnesium-calcium are related to gypsum fields and salt dome structures. The total hardness varies from 3.5 to 10.27 mg/eq/l from moderately hard to extremely hard. The conclusion on the quantitative and qualitative assessment of spring waters should be made by prospecting and exploration activities with experimental filtration activities and assessment of reserves.
