“…The large relative mass difference between the two isotopes ( 11 B and 10 B) and the different properties of the two dominant aqueous species of boron (i.e., B(OH) 3 and B(OH) 4 − ) lead to a significant isotopic fractionation of B [10,27]. Due to their soluble and incompatible character, the unique geochemical characteristics of B isotopes are widely used to assess numerous key geological processes, such as dehydration and metamorphism during slab subduction, ancient oceanic pH levels, the evolution of the formation of continental crust [28][29][30][31][32][33], magmatism and the formation of hydrothermal ore deposits [25,26,34,35], the causes of anthropogenic contamination, wastewater recharge [36][37][38], the origin of salt lakes and groundwater [27,39,40], sedimentary environment, and water-rock interactions [41,42].…”

The Nangqen Basin is a typical shearing-extensional basin situated in the hinterland of the Tibetan Plateau. It contains abundant saline spring resources and abnormal trace element enrichments. The hydrochemical molar ratios (Na/Cl, B/Cl, and Br/Cl), H-O isotopes, and B isotopes of the saline spring were systematically measured to describe the evolution of brines and the origin of the boron. The sodium chloride coefficient of the water samples in this area is around 1.0 or slightly greater, which is characteristic of leached brines; the highest B/Cl value is 4.25 (greater than that of seawater). The Na/Cl, B/Cl, and Br/Cl values of the springs are clear indicators of a crustal origin. The18 O values of the spring waters range from −12.88‰ to −16.05‰, and the D values range from −100.91‰ to −132.98‰. Meanwhile the B content and B isotopes in the saline springs are in the ranges of 1.00 to 575.56 ppm and +3.55‰ to +29.59‰, respectively. It has been proven that the saline springs in the Nangqen Basin are a type of leached brine, suggesting that the saline springs have a terrestrial origin. The 11 B-B characteristics of the springs are similar to those observed in the Tibetan geothermal area, indicating that these two places have the same B source. Moreover, they have a crustal origin (marine carbonate rocks and volcanic rocks) instead of a deep mantle source.

“…Hydraulic connection between the stream and the groundwater can occur with a transfer of mass and/or pressure head, based on the local hydrogeological conditions [31]. The alluvial aquifers are fed by the limestone aquifers of the Apennine Mountains in the internal areas [32][33][34][35][36], while recharge from rainfall has a major role in the total recharge to the shallow alluvial aquifers moving downstream towards the sea, particularly in correspondence of the terraced deposits that are hydraulically connected to the lower valleys [37][38][39][40]. The wells considered in this study fall in the terminal areas of the Pescara River alluvial valley, near the Adriactic Sea.…”

Abstract:In this research, univariate and bivariate statistical methods were applied to rainfall, river and piezometric level datasets belonging to 24-year time series . These methods, which often are used to understand the effects of precipitation on rivers and karstic springs discharge, have been used to assess piezometric level response to rainfall and river level fluctuations in a porous aquifer. A rain gauge, a river level gauge and three wells, located in Central Italy along the lower Pescara River valley in correspondence of its important alluvial aquifer, provided the data. Statistical analysis has been used within a known hydrogeological framework, which has been refined by mean of a photo-interpretation and a GPS survey. Water-groundwater relationships were identified following the autocorrelation and cross-correlation analyses. Spectral analysis and mono-fractal features of time series were assessed to provide information on multi-year variability, data distributions, their fractal dimension and the distribution return time within the historical time series. The statistical-mathematical results were interpreted through fieldwork that identified distinct groundwater flowpaths within the aquifer and enabled the implementation of a conceptual model, improving the knowledge on water resources management tools.

“…Anthropogenic boron contamination in aquifers has been attributed to leaking septic systems (Massmann et al, 2008) and borate mining in Turkey (Gemici et al, 2008). Unlike ammonium and arsenic, high boron concentrations of geogenic origin have been more rarely reported in the literature, and most of them are related to geothermal activity (Bernard et al, 2011;Grassi et al, 2014) and Na-Cl brines (Wunsch et al, 2013;Palmucci and Rusi, 2014). High boron concentrations have also been described in deep aquifers in Bangladesh and Michigan (Ravenscroft and McArthur, 2003;Halim et al, 2010), and they are associated with chloride and Ca/Na cation exchange and are attributed to the mixing of fresh water with displaced ancient seawater.…”

High ammonium (NH4), arsenic (As) and boron (B) concentrations are found in aquifers worldwide and are often related to human activities. However, natural processes can also lead to groundwater quality problems. High NH4, As and B concentrations have been identified in the confined, deep portion of the Niebla-Posadas aquifer, which is near the Cobre Las Cruces (CLC) mining complex. The mine has implemented a Drainage and Reinjection System comprising two rings of wells around the open pit mine, were the internal ring drains and the external ring is used for water reinjection into the aquifer. Differentiating geogenic and anthropogenic sources and processes is therefore crucial to ensuring good management of groundwater in this sensitive area where groundwater is extensively used for agriculture, industry, mining and human supply. No NH4, As and B are found in the recharge area, but their concentrations increase with depth, salinity and residence time of water in the aquifer. The increased salinity down-flow is interpreted as the result of natural mixing between infiltrated meteoric water and the remains of connate waters (up to 8%) trapped within the pores. Ammonium and boron are interpreted as the result of marine solid organic matter degradation by the sulfate dissolved in the recharge water. The light δ(15)NNH4 values confirm that its origin is linked to marine organic matter. High arsenic concentrations in groundwater are interpreted as being derived from reductive dissolution of As-bearing goethite by dissolved organic matter. The lack of correlation between dissolved Fe and As is explained by the massive precipitation of siderite, which is abundantly found in the mineralization. Therefore, the presence of high arsenic, ammonium and boron concentrations is attributed to natural processes. Ammonium, arsenic, boron and salinity define three zones of groundwater quality: the first zone is close to the recharge area and contains water of sufficient quality for human drinking; the second zone is downflow and contains groundwater suitable for continuous irrigation but not drinkable due to high ammonium concentrations; and the third zone contains groundwater of elevated salinity (up to 5940 μS cm(-1)) and is not useable due to high ammonium, arsenic and boron concentrations.
