“…The result of water quality evaluation shows that Tuo River has better water quality than Bian River; according to Figure 3, the average content of sulfate in the Bian River is 306.81 mg/L, which is far beyond the quality standards of surface water in China (250 mg/L) and drinking water under the guidance of the World Health Organization (250 mg/L). Zheng et al [47] studied the δ 34 S-SO 4 content of the main surface water in this area and found that coal mining had a certain impact on the sulfate content in this area.…”

To study the disparity of river hydrochemical characteristics and water quality in different regions of the city, this paper took the Tuo River in the center of Suzhou, Northern Anhui, China and the Bian River on the edge of the urban area as the research objects, used Piper trigram, Gibbs diagram, and hydrogen and oxygen isotope content characteristics to analyze the geochemical characteristics of surface water in the study area, and then the improved fuzzy comprehensive evaluation method was used to evaluate the water quality. The results showed that the hydrochemical types of the two rivers were SO4-Cl-Na type, and the contents of Na+, K+, SO42−, Cl−, Ca2+, total phosphorus (TP) in the Bian River at the edge of the city were much higher than those in the Tuo River at the center of the city (ANOVA, p < 0.001). Gibbs diagram showed that the ion composition of the two rivers was mainly affected by rock weathering. The results of correlation analysis and water quality evaluation showed that Bian River was greatly affected by agricultural non-point source pollution, and its water quality was poor, class IV and class V water account for 95%, while, for Tuo River, due to the strong artificial protection, class II and class III accounted for 40.74% and 59.26%, respectively, and the overall water quality was better than that of Bian River. The evaluation results of irrigation water quality showed that the samples from Tuo River were high in salt and low in alkali, which could be used for irrigation when the soil leaching conditions were good, while Bian River water samples were high in salt and medium in alkali, which was suitable for irrigation of plants with strong salt tolerance.

“…The interactions between precipitation and groundwater can be investigated using stable isotopes of hydrogen and oxygen [26][27][28][29]. The application of isotope tracers (δ 34 S-SO 4 2 , δ 18 O-SO 4 2 ) in identifying sources and fate of SO 4 in groundwater has been successfully achieved for several decades [30][31][32][33][34][35]. The geochemical evolution of karst water and its associations with urbanization impacts have not been fully addressed in the karst regions throughout the world [36][37][38][39][40][41][42].…”

Karst groundwater in the Niangziguan spring fields is the main source to supply domestic and industrial water demands in Yangquan City, China. However, the safety of water supply in this region has recently suffered from deteriorating quality levels. Therefore, identifying pollution sources and causes is crucial for maintaining a reliable water supply. In this study, a systematic sample collection for the karst groundwater in the Niangziguan spring fields was implemented to identify hydrochemical characteristics of the karst groundwater through comprehensive analyses of hydrochemistry (piper diagram, and ion ratios,) and stable isotopes (S and H-O). The results show that the karst groundwater in the Niangziguan spring fields was categorized as SO4·HCO3-Ca·Mg, HCO3·SO4-Ca·Mg, and SO4-Ca types. K+, Cl-, and Na+ are mainly sourced from urban sewage and coal mine drainage. In addition, SO42− was mainly supplied by the dissolution of gypsum and the oxidation of FeS2 in coal-bearing strata. It is noteworthy that, based on H-O and S isotopes, 75% of the karst groundwater was contaminated by acidic water in coal mines at different degrees. In the groundwater of the Niangziguan spring field, the proportions of SO42− derived from FeS2 oxidation were 60.6% (N50, Chengxi spring), 30.3% (N51, Wulong spring), and 26.0% (N52, Four springs mixed with water). Acid mine drainage directly recharges and pollutes karst groundwater through faults or abandoned boreholes, or discharges to rivers, and indirectly pollutes karst groundwater through river infiltration in carbonate exposed areas. The main source of rapid increase of sulfate in karst groundwater is acid water from abandoned coal mines.

“…Rivers are an important components of surface water, playing an important role in the global biogeochemical cycle (Zheng et al 2019). The dissolved matter in rivers carries abundant information regarding the geological and human activity, is an important channel of land and marine material, and is closely related to global climate change (Stögbauer et al 2008).…”

“…The δ 34 S SO4 and δ 18 O SO4 can be used to distinguish natural and anthropogenic sulfates (Wynn et al 2014). The isotopes have also been extensively used to trace sulfate sources in water (Wynn et al 2014;Shin et al 2015;Zheng et al 2019). In the industrialized countries of the Northern Hemisphere, the value of δ 34 S SO4 in SO 4 2À , which is mainly caused by man-made pollution in atmospheric precipitation, generally varies form À3‰ to þ9‰ (Zhang 2015).…”

Throughout the last few decades, sulfate concentrations in streamwater have received considerable attention due to their dominant role in anthropogenic acidification of surface waters. In order to determine the cycle of riverine sulfate, affected by natural weathering and anthropogenic activities, the Zhuzhaoxin River Basin and Dongyu River Basin in Heze City, China are selected. The conventional hydrochemical characteristics, distribution characteristics of sulfate concentration, and distribution characteristics of sulfur and oxygen isotopes are analyzed and texted. The results are as follows: The concentration of SO42− in the surface water of the study area increased gradually from upstream to downstream. In the study area, the δ34SSO4 and δ18OSO4 value in the surface water of Zhuzhaoxin River Basin ranges from +8.0‰ to +22.3‰ and +7.3‰ to +10.5‰, respectively, while the values of Dongyu River Basin are between +9.3‰ ∼ +9.5‰ and +4.2‰ ∼ +8.1‰. The main sources of SO42− in the Zhuzhaoxin River Basin are domestic sewage, industrial and mining wastewater and the evaporation of dissolved salt rock, and their average contribution rates are more than 50 and 30% respectively; the main sources of SO42− in the Dongyu River Basin are agricultural activities and atmospheric precipitation, and their average contribution rates are more than 60 and 20%, respectively.
