“…Although (i) different types of MAR schemes are widely distributed and applied on various scales and for various purposes in the European countries (Sprenger et al, 2017), and (ii) the effectiveness of MAR in European mountain regions is well known since centuries ago (Martos‐Rosillo et al, 2019), MAR is poorly implemented in Alpine and pre‐Alpine regions. Available databases (Sprenger et al, 2017; Stefan & Ansems, 2018) show that very few are the locations (along the Rhine River close to Basel and the Arve River in Geneva, Switzerland; de los Cobos, 2002) where MAR is ongoing to replenish aquifers using surplus surface waters. This evidently contrasts, for example, with the ongoing practice in the Netherlands where managed recharge of coastal aquifers is widely implemented (Stuyfzand & Doomen, 2004).…”

Managed aquifer recharge (MAR) is becoming a common practice worldwide. MAR is carried out in different environments from coastlands to highlands, in megalopolis, farmlands and pristine areas, and in arid and humid regions. Pre-Alpine aquifers represent an optimal target when MAR is aimed at storing large amounts of high-quality waters. In fact, pre-Alpine aquifers are generally characterized by high permeability and a thick unsaturated zone, with the catchments crossed by watercourses rich of high-quality water. Here, we focus the attention to a representative pre-Alpine aquifer system located in the Friuli region, northeastern Italy. A 1-year long MAR test was carried out through a~700 m 2 infiltration basin recharged by water diverted from a nearby channel. The site was characterized from the hydrogeological viewpoint, and the MAR test was monitored through time-lapse hydrogeophysics, water level and piezometric records, and physicochemical water characterization. The data set was used to calibrate a local groundwater flow model, showing that MAR recharged the 50 m deep phreatic aquifer with 1,000 m 3 /day. Hydrogeologic data made available by previous studies were processed to develop a groundwater model of the regional aquifer that allowed for estimating the natural groundwater recharge of the phreatic system and, subsequently, evaluating the MAR effects in the context of the natural balance. If a single MAR site, like the tested one, plays a certain effect at a local scale only, the MAR implementation on several gravel pits and large-diameter wells scattered in the region could store several million cubic meters of water per year, significantly raising the water table and improving the groundwater quality.

“…Numerous studies published in the field cover various aspects of MAR, including water recycling [5], recharge and recovery using wells [6], technologies and engineering for artificial recharge [7], riverbank filtration [8], MAR case risk assessment [9], sustainable groundwater management through artificial recharge [10,11], the progression of MAR practices in China, USA, and Europe [12][13][14], and the historical evolution of artificial recharge in the coastal dunes of the Netherlands [15]. Some examples of operational MAR systems include the large-scale infiltration basins in the Burdekin Delta in Queensland, Australia [16], the subsurface infiltration galleries of the aquifer recharge system of Geneva in Switzerland [17], the aquifer storage and recovery system in the Upper Floridian Aquifer System in the USA [18], underground dams in Shandong Peninsula, China [13], and the Amsterdam Water Supply Dunes system in the Netherlands [15].…”

Jinan, China, is famous for its springs. However, societal and economic development over the past decades has detrimentally altered the natural water cycle in the spring area. Managed aquifer recharge (MAR) is an effective measure to ensure the normal gushing of springs. Balancing water resource utilisation, ecological effects, and water quality risks is not always easy to implement. This study focused on the potential effects of MAR projects that divert water from multiple local surface water sites, e.g., the Yellow River and South-to-North Water Diversion (SNWD) Project. A numerical simulation model for the entire spring area was built using MODFLOW and MT3DMS. The SNWD Project diverts water with relatively high total dissolved solids (TDS) to the Yufu River, which consequently recharges groundwater and poses a potential risk to the downstream karst water in the Jinan Spring area. Different simulation scenarios were set, and the results showed that the 90% recovery ratio scheme yields the highest TDS reduction efficiency as well as the largest karst water extraction volume. In addition, the water table remains stable as a whole. The benefits of the designed scheme are multifold, including improving water quality up to Standard III groundwater quality and meeting the water needs of the economy. The study provides a novel method of addressing the groundwater quality risks posed by artificial recharge.

“…Conjunctive water management allows the combined use of surface water and groundwater and other non-conventional sources (UNESCO-IHP Groundwater Portal, n.d.). In Geneva, for instance, household water is supplied partly from groundwater, partly from Lake Geneva; the groundwater component replenished also by recharge from the Arve River (de los Cobos, 2002). Groundwater supplying Berlin is bank filtrate from percolated stormwater and surface water, benefitting from natural cleaning while passing through soil.…”

Since the late 1800s, the source selection – surface water or groundwater – for urban water supply has faced several policy changes in Finland. First, groundwater was favored. In 1920, driven by cost and reliability issues, one major city turned to surface water which was a sourcing determination for the country. After WWII, groundwater gradually gained preference motivated by reliability, including managed aquifer recharge since 1970. Instead of identified policy decisions, this shift was based on accumulated strategy. Since the 1980s security issues have favored groundwater while environmental concerns manifest themselves controversially. As a sub-study, treated lake water and groundwater were tasted by 167 persons of whom 86% preferred the latter. An additional expert survey (n=14) showed several benefits for groundwater. Combining these findings, groundwater has several advantages over surface water for Finnish urban water. Yet, for the futures, we need to keep both water sources in as good condition as possible.
