“…Sulfide oxidation usually results in minimal S isotopic fractionation [ 64 , 65 ], basically preserving the original isotopic composition of the sulfide minerals. However, the oxygen in water and the atmosphere participates in sulfide oxidation in different proportions, resulting in the extremely complex behavior of δ 18 O−SO 4 2− [ 66 ]. In Figure 5 , the δ 34 S−SO 4 2− values of most UZ samples were close to the δ 34 S−SO 4 2− range (+6.3‰~+13.5‰, mean 9.9‰) of the precursor sulfide minerals (pyrite) in the coal mine area, as reported by Chen et al [ 21 ], indicating that the δ 34 S−SO 4 2− signatures resulted from the oxidation of sulfide.…”

Mining activities cause surface sulfate enrichment, which has negative impacts on human health and ecosystems. These high concentrations of sulfate may enter groundwater through the unsaturated zone (UZ), threatening groundwater quality. Therefore, we combined hydrochemical and dual isotopic analyses of sulfate in surface water, soil water and groundwater with evaluations of the UZ to identify the groundwater sulfate source and transformation in the coal mining area. Soil profile samples were collected near gangue heaps (UZ−1, UZ−2) and the mean sulfate concentrations of the UZ−1 profile and UZ−2 profile were 35.4 mg/L and 69.63 mg/L, respectively. The shallow groundwater sulfate was mainly from dissolution of evaporite, sulfide oxidation and sewage. Different sulfate contaminated areas showed different characteristics of sulfate sources. The sulfate source to groundwater near the coal gangue heaps was sulfide oxidation. The groundwater sulfate near the gangue heaps and industrial park compound contamination area was mainly derived from industrial and domestic sewage and sulfide oxidation. In addition, the role of bacterial sulfate reduction (BSR) in the groundwater was not obvious. This research result is of great significance for promoting the safe mining of coal resources and sustainable utilization of groundwater in the Huaibei coal mining area and other coal mining areas in China.

“…Esse resultado pode estar relacionado com a formação geológica da bacia hidrográfica, constituída de rocha ígnea, como o basalto, que possui em sua composição mineralógica o sulfeto. Ao realizar investigações isotópicas de enxofre e oxigênio em seis minas da Coreia do Sul, a concentração de sulfeto ocorreu nas águas superficiais e subterrâneas, em razão da presença da rocha granito, do grupo de rochas ígneas (KIM et al, 2019).…”

This paper aimed to analyze the influence of land use on the quality of water in Uberabinha river basin in the city of Uberlândia (MG). Using geoprocessing techniques and remote sensing data, land use, soil type, slope and hypsometric maps were drawn. Images were taken from the LANDSAT 8 satellite with 30 m space resolution, dated August 18, 2018, and from the Digital Elevation Model TOPODATA/SRTM together with the historical series data about water quality of the Uberabinha river, retrieved from Instituto Mineiro de Gestão das Águas (IGAM) and the Brazilian Ministry of Health. The data about water quality were organized according to the limits established by Conselho Nacional do Meio Ambiente (CONAMA) and international regulation. Uberabinha river basin is mostly used for agriculture. Concerning the water quality sampled from point PB 023, which was sixteen kilometers away from Uberlândia's sewage treatment plant (STP), the concentration of the variables totalscoliform index, Escherichia coli, sulfate, and phosphorus exceeded the limits set by laws between 2012 and 2018. Water quality data were collected on an annually basis, always in August. The land use influenced on the contamination of the basin water, especially, in the course that includes Uberlândia's urban area, due to a greater concentration of the parameters that indicate contamination of domestic and industrial water

“…The sulfur isotope compositions of sulfate are different if the sulfate sources are different (Brenot et al, 2007;Ingri, Torssander, Andersson, Morth & Kusakabem, 1997;Krouse & Mayer, 2000;Morth, Torssander, Kusakabe & Hultberg, 1999;Schiff, Spoelstra, Semkin & Jeffries, 2005;Tuttle, Breit & Cozzarelli, 2009;Yoon et al, 2008;Yuan & Mayer, 2012 ). Therefore, stable sulfur isotopes have been used in the past several decades to track the sources of dissolved sulfates (Hosono, Delinom, Nakano, Kagabu & Shimada, 2011;Killingsworth & Bao, 2015;Kim, Yun, Yoon & Mayer, 2019;Rivas, Pozo & Paz, 2014;Valiente et al, 2017;Yoon et al, 2008;Zhou et al, 2016; ). However, it is difficult to study the original sources of dissolved sulfates in lakes; e.g., the dissolved sulfates from atmospheric precipitation and sulfide have the same isotope signature (Mayer, Shanley, Bailey & Mitchell, 2010;Yang et al, 2010 ;Tuttle et al, 2009).…”

Since the Eastern Route of the South-to-North Water Diversion Project (SNWD-ERP) officially began operation, it was found that the concentrations of sulfate rapidly increased after water transfer from Jiangsu Province to Shandong Province, especially in Nansi Lake (NSL). The direct and original sources of sulfate in NSL and its surrounding inflowing rivers were investigated by analyzing the hydrochemical properties of the water bodies and sulfur and oxygen isotope compositions of dissolved sulfate during nondiversion and diversion water periods. During the diversion water period, the largest direct source of high SO42concentrations in NSL was evaporite dissolution, accounting for 52.18% of the total contribution. In contrast, during the nondiversion water period, the maximum contribution of SO42-came from inflowing river inputs. To ensure the safety of the water supply of the SNWD-ERP, some measures must be taken to decrease the sulfate inputs from inflowing rivers, such as formulating strict discharge standards to reduce the direct discharge of sewage into the inflowing rivers around NSL.Using sulfur and oxygen isotopes to analyze the source of sulfate associated with the Eastern Route of the South-to-North Water Diversion Project in China
