Geochemistry of Groundwater

Dear Colleagues,

Groundwater is a complex and intriguing geosystem ubiquitously diffused on Earth. It is the main source of water for humankind and the place where meteoric and deep fluids mix, carrying information about geodynamic processes acting at deeper levels of the lithosphere. Its equilibria are affected by quantitative and qualitative pressures, such as pollution, overexploitation, and alterations of the hydrological cycle driven by climatic changes. Geochemistry is a powerful tool for investigating resistance/resilience of groundwater to such changes.

This Special Issue of Water calls for contributions on these subjects, with a particular focus on the geochemical proxies of both anthropogenic and geogenic processes altering the current equilibria of groundwater. A non-exhaustive list of possible contributions includes recent advances in geochemical modeling of groundwater; new equipment and methods for the near-continuous monitoring of geochemical parameters of groundwater; transport and fates of minor, trace, and ultra-trace elements in groundwater; water–rock and meteoric–deep fluid interaction processes in active seismic and volcanic areas; transport and fate of pollutants in groundwater; geochemical proxies of sea intrusion in coastal aquifers; spatial modeling and mapping of geochemical parameters of groundwater; isotopic signature of groundwater, and associated meteoric recharge, as a tool for reconstructing groundwater circulation schemes; and the chemical and isotopic signature of gas phases dissolved in groundwater, with a special focus on active seismic and volcanic areas.

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 250 words) can be sent to the Editorial Office for assessment.

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. Water 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 2600 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.
