“…This method obviously requires the existence of solid databases on the quality of groundwater, as well as a strong spatial constraint provided by the compartmentalization into groundwater bodies. As this information was supported by the European Water Framework Directive, it should be available in the majority of the European Community countries [19,[35][36][37][38]. In our case, after studying areas ranging from 3000 to 10,000 km 2 , i.e., two or three departments according to the French administrative division, it appeared that studying the sources of spatial variability over larger areas (for example the PACA region of around 30,000 km 2 ) requires the development of an appropriate methodology.…”

“…Driven by the European Water Framework Directive (WFD) in 2000 [19,20], the Water Agencies with the support of the French Geological Survey (BRGM) inventoried underground water reservoirs on a national scale, which were then subdivided into groundwater bodies (GWB units of the Water Information System for Europe: WISE) referred to hereafter as MESO (for Masse d'Eau SOuterraines in French). MESO corresponds to a distinct volume of groundwater in one or more aquifers, an aquifer representing one or more underground layers of sufficient porosity and permeability to allow either a significant groundwater flow or the capture of large quantities of groundwater.…”

In France, the data resulting from monitoring water intended for human consumption are integrated into a national database called SISE-Eaux, a useful and relevant tool for studying the quality of raw and distributed water. A previous study carried out on all the data from the Provence-Alpes-Côte d’Azur (PACA) region in south-eastern France (1061 sampling points, 5295 analyses and 15 parameters) revealed that the dilution of the information in a heterogeneous environment constitutes an obstacle to the analysis of ongoing processes that are sources of variability. In this article, cross-referencing this information with the compartmentalization into groundwater bodies (MESO) provides a hydrogeological constraint on the dataset that can help to better define more homogeneous subsets and improve the interpretation. The approach involves three steps: (1) A principal component analysis conducted on the whole dataset aimed at eliminating information redundancy; (2) an unsupervised grouping of groundwater bodies having similar sources of variability; (3) a principal component analysis carried out within the main groups and sub-groups identified, aiming to define and prioritize the sources of variability and the associated processes. The results supported by discriminant analysis and machine learning show that the grouping of MESO is the best-suited scale to study ongoing processes due to greater homogeneity. One of the eight main groups identified in PACA, corresponding to the accompanying aquifers of the main rivers, is analyzed by way of illustration. Water–rock interactions, redox processes and their effects on the release of metals, arsenic and fecal contamination along different pathways were specifically identified with varying impacts according to the subgroups. We discussed both the significance of the principal components and the mean values of the bacteriological parameters, which provide information on the causes and on the state of contamination, respectively. Based on the results from two different groups of MESO, some guidelines in terms of a strategy for resource quality monitoring are proposed.

“…Safe drinking water is becoming a scarce commodity in many parts of the world, and several countries rely on groundwater systems for its supply ( 1 ). However, with the advent of modern agriculture, urbanization, and other anthropogenic practices, groundwater reservoirs are threatened by the leaching of chemical pollutants and their toxic degradation products ( 2 ).…”

“…During the last decades, an increasing global awareness regarding the key ecological, hydrological, and economic roles of groundwater bodies has driven both national and international authorities to create instruments intended to protect aquifer systems from pollution and assure the normal provision of ecosystem services. A good example of such practices are fundamental norms included in European river basin management plans, as required by the Water Framework Directive and by the Groundwater Directive of the European Union [4][5][6][7].…”

An Open Source GIS-Based Application for the Assessment of Groundwater Vulnerability to Pollution

2019

Groundwater is a crucial natural resource for regular socio-economic function. Groundwater vulnerability to pollution can be assessed through Geographical Information System (GIS)-based qualitative methods. GIS-based tools, dedicated to the assessment of groundwater vulnerability, usually present several limitations, such as high cost, unavailable code, and a lack of functionality concerning the flexible application of vulnerability indices and vulnerability map comparison. The objective of this work was to create a new GIS-based open source application for groundwater vulnerability assessment, GVTool, developed using QGIS software, with the capability of creating and comparing groundwater vulnerability maps considering four different methods: DRASTIC, GOD, SINTACS, and Susceptibility Index (SI). This application incorporates features from a previous tool, DRASTIC Model, and new functionalities were included, namely three additional vulnerability assessment methods, map comparative analysis, map statistics, and index interval reclassification and symbology definition. The GVTool functionalities and capabilities are illustrated through a groundwater vulnerability assessment in Serra da Estrela mountain (Central Portugal). GVTool is mostly useful in integrated assessments, helping to verify if the groundwater vulnerability maps are accurate and to decide which is the most suitable method or the combination of methods to express groundwater vulnerability to pollution in a specific area.
