Theoretical bases of information support of geological prospecting researches and works on use and protection of underground waters are considered. The methodology of information support is based on the principles of target infogeological structuring of the geological environment on the basis of traditional methods of formational analysis taking into account hydrogeological (hydrodynamic and hydrochemical) components. Prospects for the introduction of a system of frame organization of the geological environment in infogeological modeling are discussed. In the applied sense, research focuses on that part of the underground hydrosphere that is now or in the future able to meet the needs of mankind in drinking, mineral, technical, industrial, thermal waters. The principles of management of groundwater resources based on the ratio of renewable natural (dynamic resources, which make up the majority of open hydrodynamic systems in the zone of intensive water exchange), renewable manmade (artificial or disturbed resources) and non-renewable components (capacitive reserves and semi-closed structures). Accordingly, during the operation of deposits, not only the calculated value of the allowable level reduction but also the "allowable balance" of groundwater should be observed. It is also proposed to define and agree on the boundaries of deposits and boundary conditions. The latter should be responsible not only for the water intake production, but also to demonstrate the degree of hydrodynamic, hydrochemical, geological protection and the risk of quantitative and qualitative depletion. Groundwater extraction must be balanced by restoring their reserves, which can be achieved by combined alternate water use of surface and groundwater sources, the creation of infiltration basins and more. On this conceptual basis, a system of information support for research and work on the use and protection of groundwater is proposed, which in the long run should be as close as possible to world standards.

Abstract Coastal areas worldwide are often densely populated and host regional agricultural and industrial hubs. Strict water quality requirements for agricultural, industrial and domestic use are often not satisfied by surface waters in coastal areas and consequently lead to over-exploitation of local fresh groundwater resources. Additional pressure by both climate change and population growth further intensifies the upcoming water stress and raise the urgency to search for new fresh water sources. In recent years, offshore fresh groundwater reserves have been identified as such a potential water source. In this study, we quantify, for the first time, the global volume of offshore fresh groundwater in unconsolidated coastal aquifers and show that it is a viable option as additional fresh water source in coastal areas. Our results confirm previously reported widespread presence of offshore fresh groundwater along the global coastline. Furthermore, we find that these reserves are likely non-renewable as they were deposited during glacial periods when sea levels were substantially lower compared to current sea level. We estimate the total offshore fresh groundwater volume in unconsolidated coastal aquifers to be approximately 1.06 ± 0.2 million km³, which is roughly three times more than estimated previously and about 10% of all terrestrial fresh groundwater. With extensive active and inactive offshore oil pumping present in areas of large offshore fresh groundwater reserves, they could be considered for temporary fresh groundwater exploration as part of a transition to sustainable water use in coastal areas on the long run.

The results of the study of the ecological-hydrogeochemical state of the underground waters of the Chop-Mukachevo basin and the identification of its spatio-temporal changes in the chemical composition using GIS facilities are presented. The methodology for processing the initial hydrogeological data on the basis of geographic information technologies has been improved and tested on the example of spatio-temporal changes in the indicators of chemical composition. A specialized geoinformation database of the chemical composition of groundwater has been created. The evaluation of spatio-temporal patterns of changes in the chemical composition using statistical analysis, cartographic modeling, and spatial analysis in GIS, identified areas with increased salinity and hardness of groundwater. Based on an integrated approach, zoning was performed and the current hydrogeochemical state of the groundwater resources of the study area was evaluated.

Local Resource Management

Despite efforts to reform management of water resources, groundwater levels have continued to decline steadily in key aquifers across India, leading to serious environmental concerns and impacts. While policy makers have looked to efforts aimed at improving the efficiency of field-level irrigation and strengthening ownership and property rights in local resource management, hydrologists have asserted that more direct control of consumptive use patterns of water is needed. In this paper, we illustrate the divergence between current groundwater usage patterns and an optimal path, in which the groundwater levels are stabilized with better demand-side management. The paper assesses the tradeoffs embedded in alternative policy instruments that are aimed at modifying the groundwater pumping behavior of agricultural water users. The challenges of regulating smallholder agricultural water users are shown to be relevant in determining which instrument might have the best chance of slowing the depletion of groundwater resources in the hard-rock aquifers of India, and promoting the long-run sustainability of this critical natural resource.

AbstractMunicipal wastewater irrigation induces elevated concentrations of heavy metals in the soil which their further leaching leads to groundwater contamination in the long run. In this study, both column experiment and 5-year prediction modeling using HYDRUS-1D were conducted to investigate the probable adsorption and transport of 10 different metals including As, Ba, Cr, Cu, Mo, Ni, Pb, Rb, Sr, and Zn in an alkaline soil from Nazarabad plain in Iran which has been irrigated with treated urban wastewater for several years. The obtained results revealed that reaching the equilibrium rate for the mentioned elements during 1825 days (= 5 years) was as follows: Mo > Cr > Rb > Zn > Ni > Ba> Sr > Pb > As> Cu. The finding implies that molybdenum (Mo) and copper (Cu) are the most mobile and the most adsorbent heavy metals in the soil, respectively. Higher mobility poses the greater potential risk of leaching into groundwater resources. Overall, experimental and numerical modelings had good accordance and were capable of describing the actual condition.

Hydrogeochemical Characterization

This paper presents a comparative hydrogeochemical characterization on the predominant ions of the underground water that flow the Cocal vein, in the Mina 3 (Companhia Nitroquímica Brasileira), Fluorine Distritic of Santa Catarina, Morro da Fumaça Co., Santa Catarina, Brazil. Four samples were selected: P1 – underground water to 300 m of depth; P2 –underground water to 150 m of depth; P3 – water of the dam of reject; P4 – treated water of provisioning of Companhia Catarinense de Águas e Saneamento (CASAN). In the water sample collected in the selected sources, quantitative determinations of physical-chemical parameters (pH and electric conductivity) and of cations (Al, Ca, Cl, Li, Mg, Mn, K, Si, Na, and Zn) and anions (sulfate, chloride, bicarbonate, and fluorine) were performed. The results obtained revealed that most of the analyzed ions are related to the representatives that originated from rocks that constitute the pools where the studied water flow. The hydrogeochemical classification was obtained starting from the miliequivalence pattern among the main elements, in the cations and anions form being used the triangular diagram of Piper. The underground water of the point 1 presented a hydrogeochemical characterization compatible with is geological environment occurrence and being perceptible the characterization of an interrelation among the rock and the water that circulate within and they also presented an amount of larger ions than the water of the point 2, in since it flow through a mineralized pool. The underground water of the point 2 presented good potable conditions, with some restrictions. In the water of the point 3 there is a larger ions concentration by due to the washing of the mineral, that allows a larger solubilization of the elements, and the time of permanence of the water in the lake also causes larges concentration. The water collected in P4 point exhibit good water potability parameters and absence of conditions that favor fluorosis.

The main working tool is a targeted multi-scale information modeling of promising geological objects, based on the general theoretical scheme of forecast-paleoreconstructive retrospective-static model with the introduction of the concept of formation-material system of oil and gas accumulation, which includes three cognitive-functional components: initial source, transportation and objects of hydrocarbons localization. This methodological apparatus provides solutions to the main forecasting and diagnostic tasks: development of localization criteria, forecasting of traps and assessment of the potential of their hydrocarbons realization. The proposed apparatus is multi-scale, i.e. one that provides forecasting at the zonal (group of deposits), local (deposits) and sublocal (productive beds) levels. Prospects for further development of the direction are to develop a modern holistic theory of geoinformatic modeling and its subject methodological and methodological section – frame organization of the geological environment of oil and gas specialization in order to innovatively increase the efficiency of hydrocarbon field development. The examples of updated target information modeling of promising geological objects, basing upon methodological approach of infogeology with introducing of geological environment frame organization principles are demonstrated.

The results of multi-year regional geological, geophysical, oil, and hydrogeological exploration related to the study of seas and oceans were used to characterize the submarine hydrogeological structures of the Sea of Okhotsk region - hydrogeological massifs, artesian and volcanogenic basins. The hydrogeological stratification of the geological cross-section was performed, according to which five Cenozoic aquifer systems were distinguished in the artesian basins. The chemical composition of submarine groundwater was characterized, whose mineralization decreases with depth from 27–30 g/dm3 to14–20 g/dm3. Gases (mainly methane) and thermal waters forming orebodies of metallic sulfides and non-metallic minerals are discharged into the bottom sea waters along zones of tectonic faults.
