“…Such local variability in MBR is often overlooked when quantifying basin-wide estimates but is clearly evident in Table 1 for studies like Liu and Yamanaka (2012) and others discussed below that report MBR contributions for individual wells. Peng et al (2016) attributed a modest mean fraction (12%) of total recharge to the Langyang alluvial fan aquifer in Taiwan to MBR using stable isotopes and electrical conductivity (EC) in an EMMA model. They later applied this same approach in the eastern coastal plain of Taiwan and found more significant fractions of MBR (22-54%) that correlated with mountain-block geology (Peng et al, 2018).…”

Mountain‐block recharge (MBR) is the subsurface inflow of groundwater to lowland aquifers from adjacent mountains. MBR can be a major component of recharge but remains difficult to characterize and quantify due to limited hydrogeologic, climatic, and other data in the mountain block and at the mountain front. The number of MBR‐related studies has increased dramatically in the 15 years since the last review of the topic was conducted by Wilson and Guan (2004), generating important advancements. We review this recent body of literature, summarize current understanding of factors controlling MBR, and provide recommendations for future research priorities. Prior to 2004, most MBR studies were performed in the southwestern United States. Since then, numerous studies have detected and quantified MBR in basins around the world, typically estimating MBR to be 5–50% of basin‐fill aquifer recharge. Theoretical studies using generic numerical modeling domains have revealed fundamental hydrogeologic and topographic controls on the amount of MBR and where it originates within the mountain block. Several mountain‐focused hydrogeologic studies have confirmed the widespread existence of mountain bedrock aquifers hosting considerable groundwater flow and, in some cases, identified the occurrence of interbasin flow leaving headwater catchments in the subsurface—both of which are required for MBR to occur. Future MBR research should focus on the collection of high‐priority data (e.g., subsurface data near the mountain front and within the mountain block) and the development of sophisticated coupled models calibrated to multiple data types to best constrain MBR and predict how it may change in response to climate warming.

“…The total concentration of NP ranged from ND to 632.9 ng/L in one sample, while the average was 398.9±259.4 ng/L. The total concentration of NP changed obviously with the depth of groundwater, which may be related to the lithologic character of monitoring wells and the recharge sources of groundwater [9,10]. Chloridion is often used as a tracer, so in order to study the recharge Beijing China Yanggezhuang Feng River relationship, the chloridion in the reclaimed water and groundwater was detected.…”

Abstract. Groundwater recharge using reclaimed water is considered a promising method to alleviate groundwater depletion. However, the pollutants in the reclaimed water would be recharged into groundwater during this process and pose risk to groundwater and human. In this study, 12 isomers of NP were detected in the reclaimed water and receiving groundwater in Feng River and Yanggezhuang. The variation rule of total concentration of NP was not obvious in Feng River, while the variation rule was obvious in Yanggezhuang.

“…In this context, mixing models are commonly applied for quantifying the source contributions to a mixture (Vázquez-Suñé et al 2010), based on the different chemical signature of the endmembers. Here, various concepts are available such as endmember mixing analysis (EMMA), mixing ratios or lumped models (Christophersen and Hooper 1992;Hooper 2003; Barthold et al 2011;Jurgens et al 2014;Peng et al 2016;Tubau et al 2014), which allow an estimation of the mixing ratios for nonconservative dissolved substances whose concentration is known in the endmembers.…”

Hydrochemical evaluation of water resources and human impacts on an urban karst system, Jordan

Urban karst aquifers are threatened by anthropogenic activities, especially in semiarid developing countries. Recent water-sampling campaigns assessed the extent of groundwater-quality impairment in the Wadi Shueib in Jordan by a comprehensive hydrogeological and hydrochemical characterization of groundwater, wastewater, and imported water with its endmembers Lake Tiberias, Yarmouk River and Mukheiba wellfield. The results of a ternary mixing model with the mass ratios of Cl−/Br− and Ca2+/Mg2+ indicate that Lake Tiberias and Yarmouk River provide most of the imported water at the time of sampling in 2017 and Mukheiba wellfield provided minor amounts. The similarity in seasonal variations of Br− concentrations in the springs and the imported water revealed that imported water has generally a greater impact on groundwater than wastewater. However, the Br− concentrations also showed that the spatial wastewater impact is more visible towards urbanized areas due to increased infiltration of pollutants. The analysis of historical data series demonstrated the long-term urban impact on groundwater by an electrical conductivity increase over several decades, particularly since the mid-1990s, which is related to a doubling of Jordan’s population since that time and the associated urban growth. In this context, increased chloride and sulfate concentrations are noticeable due to the increased impact of more highly mineralized imported water and wastewater and decreasing recharge of low-mineralized rainwater. This study showed the hydrochemical differences in the Wadi Shueib groundwater system and serves as an example for the spatial and long-term response of karst aquifers to anthropogenic, seasonally variable input of imported water and wastewater.
