“…Pumping groundwater in urbanised coastal zones is extremily complicate because of poor water quality and quantity (Eftimi et al 2017;Kouzana et al 2007); moreover, worldwide and local climate change affect the rainfall quantity, which may trigger saltwater intrusion towards fresh groundwater (Beretta 2021;Farina et al 2016;Freeze and Cherry 1979;Lukač Reberski et al 2020;Pardo-Igúzquiza et al 2019). Therefore, groundwater pumping in coastal zone needs to be monitored in order to avoid an increase of ions concentrations carrying to a variation in time and space of water quality in the aquifers (Azonsi et al 2003, Kouzana et al 2007.…”

The aqueduct serving the municipalities of Formia and Gaeta (Latina province, Italy), an area under the enforcement and control responsibility of “ATO 4” Autorità d’Ambito Territoriale Ottimale – (Integrated Urban Water Management Agency), is supplied by two important karst springs. These springs, fed by the western Aurunci Mountains system are known as Mazzoccolo and Capodacqua having an average flow rates of 1100 l/s and 1300 l/s, respectively. Although these sources have been used since ancient Roman times and the quality of their water is excellent, variations in the precipitation regime, possibly related to worldwide climate changes, has exacerbated the following problems: a decrease in the flow rates of the springs caused by the reduction in winter rainfall, and an increase of turbidity due to concentrated rainfall events. In order to mitigate these problems, which affect a resident population of about 150,000 inhabitants, Acqualatina S.p.A. - the water utility company - promoted a series of geological and hydrogeological surveys. These studies aim at increasing the knowledge on the geological setting and to find additional sources to improve the existing supply. Within the framework of these activities, we studied a strategy aimed at diversifying the water supply by identifying new exploitable aquifers in the area, to reduce the aforementioned problems. This paper presents the results of research carried out before and during the construction of the water well field “25 Ponti” located in the coastal area of the plain of Formia. The research consisted in laboratory analyses of 130 groundwater samples and in monitoring of piezometric trends. The data show a seasonal variation in groundwater chemical composition caused also by aquifer exploitation, which in some periods of the year affects the regulated reserves. This seasonal phenomenon was however present in absence of pumping.

“…Groundwater is a vital global water resource and is under increasing pressure from contamination due to anthropogenic activities (Collet et al, 2015;Gleeson et al, 2012;Lapworth et al, 2017;Lukač Reberski et al, 2019;Simonffy, 2012;Taylor et al, 2012). Groundwater is generally less vulnerable to contamination by EOCs than surface water (White et al, 2019), but trace concentrations of many pollutants, including EOCs, are still commonly detected in groundwater (Cabeza et al, 2012;Lapworth et al, 2012Lapworth et al, , 2019Lopez et al, 2015;Moreau et al, 2019).…”

A quarter of the world's population uses groundwater from karst aquifers. A range of emerging organic contaminants (EOCs) are considered a potential threat to water resources and dependant ecosystems, and karst aquifers are the most vulnerable groundwater systems to anthropogenic pollution. This paper provides the first global compilation (based on 50 studies) of EOCs in karst aquifers and explores EOC occurrence and the use of EOCs to understand karst systems. Of the 144 compounds detected in the reviewed studies, the vast majority in karst groundwater are pharmaceuticals and pesticides. Maximum concentrations of compounds varied over five orders of magnitude, and nearly half of the detected compounds exceed 100 ng/L. Karst groundwater is shown to have lower frequency of detection and lower concentrations compared to surface waters and local shallow intergranular aquifers, but overall higher concentrations compared to other major aquifer types. A growing number of studies have demonstrated the utility of EOCs and some legacy compounds for groundwater quality assessment and as tracers for characterising karst systems. They can improve understanding of vulnerability, storage, attenuation mechanisms, and in some cases have been used to assist with catchment delineation. This is a growing research area for karst hydrogeology, and more research is needed to understand EOC contamination of karst aquifers, and to develop EOCs as tracers within karst to improve our understanding of this critical water resource.

Due to numerous droughts in recent years, the amount of surface water in arid and semi-arid regions has decreased significantly, so reliance on groundwater to meet local and regional demands has increased. The Kabgian watershed is a karst watershed in southwestern Iran that provides a significant proportion of drinking and agriculture water supplies in the area. This study identified areas with karst groundwater potential using a combination of machine learning and statistical models, including entropy-SVM-LN, entropy-SVM-SG, and entropy-SVM-RBF. To do this, 384 karst springs were identified and mapped. Sixteen factors that are related to karst potential were identified from a review of the literature, and these were compiled for the study area. The 384 locations were randomly separated into two categories for training (269 location) and validation (115 location) datasets to be used in the modeling process. The ROC curve was used to evaluate the modeling results. The models used, in general, were good at determining the location of karst groundwater potential. The evaluation showed that the E-SVM-RBF model had an area under the curve of 0.92, indicating that it was most accurate estimator of groundwater potential among the ensemble models. Evaluation of the relative importance of each of the 16 factors revealed that land use, a vector ruggedness measure, curvature, and topography roughness index were the most important explainers of the presence of karst groundwater in the study area. It was also found that the factors affecting the presence of karst springs are significantly different from non-karst springs.
