Interests: geochemical tracers in hydrological studies; interactions between water and the geological and chemical environment; quantitative understanding of chemically based processes in hydrogeochemical environments and complementary physical and biological processes and conditions; kinetics and equilibria of geochemical reactions; the movement of isotopes and soil chemistry; freshwater-seawater interactions in coastal aquifers; basic and applied research on speciation and transformation of trace metals and metalloids during biogeochemical processes in both natural and anthropogenic environments; radiogenic and stable isotope geochemistry
Within the realm of the newly evolving discipline of environmental sciences, the application of isotopes methodology is being used to an ever-increasing extent.
Application include tracing the evolution of a water mass from its origin as precipitation, through its recharge processes and ending at its occurrence in an aquifer. There is a special focus on the processes at the surface–atmosphere and land–biosphere–atmosphere interfaces, since these are the sites of major changes in isotope composition.
Isotopes can also be used to determine the origin of a specific solutes in ground water. Application of this type commonly involve stable isotopes. The list of stable isotopes that has important implications for water resources management has grown in recent years. The other main class of applications of isotopes is based on the decay of radioisotopes. Unlike stable isotope applications that shed light on geochemical processes in aquifers, the radioisotopes are primarily used to determining the relative or absolute age of water in an aquifer. Actually, the date obtained give some indication of the residence time of water in an aquifer once it has passed through the vadose zone.
In some instance, ground waters can be dated by the use of radioisotopes, although the stable isotope can also be used in some dating applications.
In the last decades is increasing interest in environmentally friendly tracers, like isotopes, because of concern has emerged about the application of artificially tracers in aquatic ecosystems due to their potentially negative impact on the environment.

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 papers will be 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. Water is an international peer-reviewed open access monthly 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 1500 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.
