Special Issue Information
Dear Colleagues,
In densely urbanized areas, groundwater constitutes an essential source of freshwater and contributes to the socioeconomic development of urban centers. Nevertheless, the ever-increasing demand for safe drinking water attributable to anthropogenic activities poses a serious threat to groundwater quality, also in relation to future water scarcity scenarios. Although several approaches have been developed to address the problem of urban aquifer pollution, the main challenges are:
- The identification of the most vulnerable areas and the potential sources responsible for groundwater contamination, considering the contribution of both historical anthropogenic activities and sources that are still active today;
- The distinction of main point sources (i.e., hotspots) from diffuse contamination, which is attributed to unknown small sources clustered in large areas and cannot be remediated;
- The delineation of contaminant plumes, which can seriously affect sensible targets (i.e., water supply wells).
Among the different approaches, GIS-based statistical techniques (e.g., logistic regression, weights of evidence), statistical analysis (e.g., cluster and multivariate analyses), numerical modeling (e.g., groundwater flow and contaminant transport models) and, more recently, stochastic modeling (e.g., null-space Monte Carlo) represent key tools for the assessment of quality deterioration of urban aquifers. The use and combination of these approaches can support water managers and public authorities in practical problems including the 1) identification of the source responsible for the contamination according to the pollution pays principle, 2) the delineation of the areas affected by a background level of contamination and not by a specific source of pollution, and 3) the implementation of strategies to remediate sources and protect intake areas.
The aim of this Special Issue of Sustainability is to provide an overview of the different and innovative approaches used to assess urban aquifer pollution, in order to gain additional and useful insights on groundwater resource protection

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sustainability is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
