“…Low lithium levels were found in some Japanese municipalities, areas of Macedonia, the East of England, and Lithuania, while higher lithium levels in public drinking water were found in several Texas counties . Interestingly, lithium levels in public drinking water comprising more than 1000 µg lithium L −1 were observed in distinct areas of several countries with high lithium salt deposits, such as Australia, Northern Argentina, Chile, and Bolivia …”

Scope Lithium is an important trace element in human nutrition and medicine. Mineral and medicinal waters may represent a significant source of dietary lithium intake. Methods and results The lithium concentration of 360 German mineral and 21 medicinal waters is determined. Based on a systematic screening, three different mineral waters exhibiting low (1.7 µg L−1), medium (171 µg L−1), and high lithium (1724 µg L−1) concentrations are chosen for an acute bioavailability study in male healthy volunteers. In Germany, a north‐east to south‐west gradient of analyzed lithium concentrations is observed in the 381 tested waters. The lithium concentration in the water is significantly correlated with its sodium (r = 0. 810), potassium (r = 0.716), and magnesium (r = 0.361), but not with its calcium concentration. In a randomized cross‐over trial, volunteers (n = 3×10 each) drink 1.5 L of the respective mineral waters, and lithium concentrations in serum and urine are monitored over 24 h. Consumption of the mineral waters with a medium and high lithium content results in a dose‐dependent response in serum lithium concentrations and total urinary lithium excretion. Conclusion Lithium‐rich mineral and medicinal waters may be an important and highly bioavailable lithium source for human consumption.

“…Almost all wells located in this area are used as a source of drinking water and they are manually excavated (INE, 2017). The wells around the plain and close to river have high EC values due to the lacustrine origin of sediments and by evaporative concentration in a semi-arid climate (Ormachea et al, 2013;Ramos et al, 2014). High EC values in groundwater are linked to the presence of saline groundwater (Fig.…”

“…2). The source of Ca 2+ can be partly the dissolution of calcareous rocks (Yidana et al, 2008;Ormachea et al, 2013) and sediments of Quaternary lakes deposited in drier climate between 8000 and 1500 BP (Coudrain-Ribstein et al, 1995a, 1995b, such as calcite, aragonite and dolomite as suggested by the geochemical modelling.…”

Hydrochemical investigations of groundwater and surface water were carried out to better understand the spatial distribution of As, major ions and trace elements. The study was carried out to evaluate the sources of dissolved species and elucidate the processes that govern the evolution of natural water in the Lower Katari Basin. The study area is close to the Titicaca Lake (Cohana Bay) formed by sediments of the Quaternary system, deposited in the fluvio-glacial to fluvio-lacustrine environment and geologic formations of the Devonian and Neogene system of volcanic origin. The study area has several environmental problems mainly caused by contaminants such as heavy metals, nutrients, and bacteria. These problems are linked to the urban and industrial wastes, natural geologic conditions, and mining activities carried out upstream of the Katari Basin, where rivers discharge into the Cohana Bay. A total of 37 water samples were collected during wet season, 31 groundwater samples including drinking water wells and six surface water samples. The hierarchical cluster analysis and principal component analysis were applied to hydrochemical data. Results show high salinity in groundwater related to the evaporation causing serious problems for the groundwater quality and rendering it unsuitable for drinking. Dissolved As concentration ranges from 0.7 to 89.7 μg/L; the principal source of As could be the alteration of volcanic rocks, more than 48% of the shallow groundwater samples exceeded the WHO guideline value for As and more than 22% for NO 3-. Groundwater has neutral to slightly alkaline pH, and moderately oxidizing character. The groundwater chemistry reveals considerable variability, ranging from Na-SO 4 ,Cl type through mixed Na-HCO 3 type and Ca,Na-HCO 3 ,Cl type. The distribution of trace elements shows a large range of concentrations. Speciation of As indicates that the predominant oxidation state is As (V). The geochemical modelling indicates that As could be associated with iron oxides and hydroxides which are probably the most important mineral phases for the As adsorption. The spatial distribution and the variation of dissolved As concentration in groundwater is governed by the variability in geological characteristics of the region that raises a significant concern about drinking water quality.

“…As in other volcanic regions where natural As contamination has been reported, the southern area of Lake Poopó in the Bolivian highlands, or the Altiplano, has elevated amounts of As in the water [3,183,184]. Samples of ground and surface water collected from 24 different sites, including drinking water wells and rivers, in the southern Poopó basin revealed various levels of As in shallow drinking water wells, from below detection level to 207 μg/L [3,183,184].…”

Natural Arsenic in Global Groundwaters: Distribution and Geochemical Triggers for Mobilization

The elevated concentration of arsenic (As) in the groundwaters of many countries worldwide has received much attention during recent decades. This article presents an overview of the natural geochemical processes that mobilize As from aquifer sediments into groundwater and provides a concise description of the distribution of As in different global groundwater systems, with an emphasis on the highly vulnerable regions of Southeast Asia, the USA, Latin America, and Europe. Natural biogeochemical processes and anthropogenic activities may lead to the contamination of groundwaters by increased As concentrations. The primary source of As in groundwater is predominantly natural (geogenic) and mobilized through complex biogeochemical interactions within various aquifer solids and water. Sulfide minerals such as arsenopyrite and As-substituted pyrite, as well as other sulfide minerals, are susceptible to oxidation in the near-surface environment and quantitatively release significant quantities of As in the sediments. The geochemistry of As generally is a function of its multiple oxidation states, speciation, and redox transformation. The reductive dissolution of As-bearing Fe(III) oxides and sulfide oxidation are the most common and significant geochemical triggers that release As from aquifer sediments into groundwaters. The mobilization of As in groundwater is controlled by adsorption onto metal oxyhydroxides and clay minerals. According to recent estimates, more than 130 million people worldwide potentially are exposed to As in drinking water at levels above the World Health Organization's (WHO's) guideline value of 10 μg/L. Hence, community education to strengthen public awareness, the involvement and capacity building of local stakeholders in targeting As-safe aquifers, and direct action and implementation of best practices in identifying safe groundwater sources for the installation of safe drinking water wells through action and enforcement by local governments and international water sector professionals are urgent necessities for sustainable As mitigation on a global scale.
