“…Mn is a common natural groundwater contaminant and is present at concentrations much higher than the recommended drinking water guidelines [38]. Superfluous Mn has been found in groundwater in many countries worldwide, such as western Quebec in Canada [39], the lower Kelantan River Basin on the north-eastern coast of Malaysia [40], the Balat-Teneida area in the El-Dakhla Basin in Egypt [41], and Hidalgo in Mexico [42]. Mn also exceeds the standards in groundwater in some cities in China.…”

Groundwater is the main water supply in Suzhou City in China. In recent years, heavy metal contamination of urban groundwater sources has become a serious threat to water quality and human health. Groundwater samples from 87 monitoring wells were collected in the study area and analyzed using ICP-MS spectrometry, their major heavy metals concentrations have been analyzed by a series of chemical and statistical indexes for the evaluation of pollution status and dinking suitability. We found that heavy metals are evenly distributed in the groundwater source, 10% of the samples were of excellent quality and 75% were deemed good; however, 70% of the samples exceeded the allowed Mn content. In 62% of the samples, the carcinogenic risk of As exceeded the recommended levels. Based on the non-carcinogenic health risk values, the metals could be ordered as follows: Mn>Fe>Pb>Cu> As>Zn. Mn accounted for 71% of health risk, and the total health risk was mostly due to excess As. Therefore, the levels of As, Mn, and other heavy metal elements in this region warrant urgent regulatory strategies and methods to reduce the Mn concentration should be continuously investigated.

“…This scenario creates a reducing environment that accelerates the solubilization of Mn [49]. Second, Mn concentrations increase in groundwater with the dissolution of Fe-oxyhydroxides under reducing conditions [50]. Third, groundwater is affected by the leakage of domestic sewage, characterized by low Eh and dissolved oxygen levels, in urban environments [49].…”

Investigating the Potential Role of Geological Context on Groundwater Quality: A Case Study of the Grenville and St. Lawrence Platform Geological Provinces in Quebec, Canada

The hydrogeochemical study of the Lanaudière and Eastern Mauricie regions (Canada) demonstrates that trace elements appear to be better tracers of geological influence on groundwater chemistry than major elements. Isotopic ratios and the similar chemical composition of groundwater suggest that the physicochemical parameters of groundwater have a greater effect on hydrogeochemical mechanisms than the immediate geological environment The results allow us to propose a conceptual model of groundwater geochemical evolution with the aim to guide the protection and sustainable management of regional groundwater resources in the Lanaudière and Eastern Mauricie regions. These regions were selected because of their location at the boundary of the Grenville and St. Lawrence Platform geological provinces, representing two distinct geological contexts (Precambrian crystalline rocks and Paleozoic sedimentary rocks). Regional-scale hydrogeochemical and isotopic groundwater characterization was carried out to identify the role of the differences in regional geology on groundwater quality. Our analyses included major and trace elements, stable isotopes, and multivariate statistics. Similar processes are at the origin of dissolved major chemical elements and suggest that soluble minerals common to both geological provinces control groundwater chemistry. If differences exist, they are due to the hydrogeological conditions of the samples, such as residence time or groundwater entrapment at the time of the postglacial marine incursion of the Champlain Sea, rather than the geological context. Some differences, sometimes significant, were observed for some minor elements (F−, Mn2+, H2S), which implies a more comprehensive knowledge of the chemistry of the stratigraphic units within the Lanaudière and Eastern Mauricie aquifers.

“…On the basis of equations (5) to (7), the single-salt parameters β (0)v M,X , β (1)v M,X , β (2)v M,X , and C v M,X for NaAsO 2 at each temperature were fitted and are listed in Table 5. e temperature relation coefficients a i in equations (8) to (12) were fitted and are listed in Table 6, and the fitted results of each single-salt parameter β (0)v M,X , β (1)v M,X , β (2)v M,X , and C v M,X of NaAsO 2 were in good agreement with the experimental values, which indicated that the Pitzer model we constructed is suitable to describe the volumetric properties of the binary…”

“…Arsenic (As) is a ubiquitously toxic, carcinogenic, and possibly teratogenic element [1,2], and the toxicity of arsenite (As III ) is 60 times higher than that of arsenate (As V ) in the environment [3]. Many studies show that arsenic as a carcinogenic agent poses a high risk to human health if it is released into the environment, typically arsenicosis, a serious disease mainly caused by As-contaminated drinking groundwater [4][5][6][7][8]. Apparent molar volume reveals the volume change in solution caused by changes of temperature, concentration, and pressure and further provides some basic understanding of the structure and ion interaction in aqueous solution [9].…”

Densities of sodium arsenite (NaAsO2) aqueous solution with the molality varied from 0.19570 to 1.94236 mol·kg−1 at temperature intervals of 5 K from 283.15 to 363.15 K and 101 ± 5 kPa were measured by a precise Anton Paar Digital vibrating-tube densimeter. Apparent molar volumes (VΦ) and thermal expansion coefficient (α) were obtained on the basis of experimental data. The 3D diagram of apparent molar volume against temperature and molality and the diagram of thermal expansion coefficient against molality were generated. According to the Pitzer ion-interaction equation of the apparent molar volume model, the Pitzer single-salt parameters (βM,X0υ, βM,X1υ, βM,X2υ, and CM,Xυ, MX = NaAsO2) and their temperature-dependent correlation F(i, p, T) = a1 + a2ln (T/298.15) + a3(T − 298.15) + a4/(620 − T) + a5/(T − 227) (where T is temperature in Kelvin and ai are the correlation coefficients) for NaAsO2 were obtained for the first time. The predictive apparent molar volumes agree well with the experimental values, and those results indicated that the single-salt parameters and the temperature-dependent formula are reliable.
