“…Many authors have added new parameters that impact groundwater contamination. Most frequently these were the type of land-use [17][18][19][20], lineament [21], groundwater velocity [22], and soil exchange capacity [23]. Some authors have excluded some parameters from the original DRASTC model, such as a topography and hydraulic conductivity [24], because these parameters are characterized by low spatial variability over the study area or show strong interdependence.…”

Our paper presents the possibility of applying the DRASTIC model as a useful tool to support the process of local and regional development planning. The study was carried out in the catchment of Stare Miasto Reservoir in Central Poland. In order to plan the policy to protect the reservoir and groundwater, the assessment of groundwater vulnerability to pollution was made by means of the DRASTIC model. The original model was modified by adding a new parameter called "land use." The measured nitrate concentrations were used to test the original and modified models. The results of the study revealed that the modified DRASTIC model gave more accurate predictions than the traditional model. The Pearson correlation coefficients characterising the relationship between the vulnerability index and the nitrate concentration was 0.56 before the modification and 0.69 after it. The groundwater vulnerability map is necessary for planning local development and for assessing environmental impact. The DRASTIC model is expected to be a useful tool for designing programs and strategies, e.g., for improving the quality of surface water and groundwater.

“…The DRASTIC index defines the aquifer intrinsic vulnerability; nevertheless, based on this model, contaminant-specific methods have been developed to assess groundwater vulnerability to nitrate (Jia et al, 2019;Voutchkova et al, 2021), pesticides (Al-Mallah and Al-Qurnawi, 2018;Thapa, 2018) and mining pollutants (Haque et al, 2018;Tiwari et al, 2016). Frequently, new and additional parameters have been used by other authors that include land use (Kozłowski and Sojka, 2019), lineament (Abdullah et al, 2015), proximity to rivers, residential areas, and roads (Aydi, 2018), hydraulic parameters (Lappas, I and Matiatos, I, 2014), redox state of the aquifer (Voutchkova et al, 2021), adsorption capacity of soils (Herlinger, and Viero, 2006), contamination index (Cd) and heavy metal pollution index (HPI) (Haque et al, 2018).…”

Groundwater metal pollution is a major concern in mining areas. This study proposes a new addition to the DRASTIC method (DRASTIC+Lu) to assess groundwater vulnerability to metal pollution in mining areas by combining remote sensing (to locate metal pollution sources) and the DRASTIC index. The study was performed in a mining area in northwestern Mexico showing current and historical mining activities. The proposed methodology allowed locating known and unknown sources of metal pollution (mining tailings, active/inactive mines, and areas with exposed natural geochemical anomalies). Generally, the addition of the land use (Lu) parameter causes not only a decrease in vulnerability but also highlights very high vulnerable areas and identifies new ones in the vicinity of metal pollution sources. This result is relevant to focus stewardship efforts in very high vulnerable areas. Results allowed to identify the need to implement protection and restauration measures in the Sonora river channel and its vicinity. The proposed method could be implemented in other mining areas around the world –at a low cost– to locate unknown metal pollution sources and clearly identify very high vulnerable areas that play a key role in the protection of groundwater resources.

“…Coastal plains are complex hydrological environments where the chemical composition of water is controlled by multiple natural factors such as regional discharge, rainfall, tides, and evapotranspiration (e.g., Vandenbohede and Lebbe, 2012;Da Lio et al, 2015). In addition, these regions located at the interface between oceans and the continents are highly stressed owing to their intensively use and the accumulation of the byproducts of inland human activities, that are discharged from rivers and atmospheric deposition (Pruden et al, 2006;Da et al, 2014;Wu et al, 2014;Zhu et al, 2017;Herlinger and Viero, 2007;Graber et al, 2008;Güler et al, 2012). Therefore, an integrated understanding of fundamental physical and chemical processes is required to manage coastal resources more efficiently, based on site-specific comparative studies of coastal environments.…”

“…Modifications to the hydrological functioning and to the water quality are commonly registered in coastal plains with industrial development worldwide (e.g., Vecchioli, 1998;Herlinger and Viero, 2007;Botté et al, 2010;Marcovecchio et al, 2010;La Colla et al, 2015;Sá et al, 2015). The coastal plain of the Río de la Plata is one of the most extensive of the Atlantic coast of South America.…”

The coastal plain of the middle estuary of the Río de la Plata is a highly industrialized area and is densely populated by sectors. The main human activity in the sector encompassed between the cities of Ensenada and Berisso is associated with the petrochemical industry. In this work, hydrogeochemical and isotopic characteristics of surface and groundwater in the impacted area are analyzed and the results are contrasted with those obtained in an undisturbed protected area. Major and trace elements were determined using standardized methods while the stable isotopes δO y δH were analyzed by mass spectroscopy. Human impact is evidenced by the occurrence of large variations in the major chemical composition of water, and also by the elevated concentrations of some trace elements that are not contributed from natural sources. These results may contribute to the understanding of chemical processes and pollutants distribution in highly industrialized coastal plain areas.
