A new paper, co-authored by Drs. Stephane Ngueleu, Fereidoun Rezanezhad and Philippe Van Cappellen, has been published in Journal of Geofluids. The article, titled "Biodegradation Kinetics of Benzene and Naphthalene in the Vadose and Saturated Zones of a (Semi)-arid Saline Coastal Soil Environment", was written in collaboration with Drs. Riyadh Al-Raoush and Saeid Shafieiyoun from Qatar University.

In a new paper, ERG members Adrian Mellage, Christina Smeaton, Fereidoun Rezanezhad and Philippe Van Cappellen, together with colleagues from Technion and University of Delaware, describe the results of a fully saturated sand-filled column reactor experiment where the growth of the bacterium Shewanella oneidensis during nitrate reduction to ammonium is monitored using spectral induced polarization (SIP).

A new paper in Water Resources Research, co-authored by ERG members Serghei Bocaniov and Philippe Van Cappellen, assesses the fate of phosphorus loads to Lake St. Clair. The outflow of this fairly large but shallow lake enters Lake Erie, which has been experiencing re-eutrophication since the mid-1990s.

Camille Vautier successfully defended her PhD thesis at Université de Rennes 1 on Monday December 16. Ms. Vautier visited the Ecohydrology Research Group in July 2019 as an International Visiting Graduate Student in order to discuss her research on the water quality impacts of agricultural nitrogen legacies.

Ecohydrology members presented research at this year's fall meeting of the American Geophyiscal Union (AGU), which was the centennial year of the event. The conference was held in San Francisco, California, from December 9 to December 13.

A paper by ERG researchers in the journal Environmental Science & Technology reports the results of an experimental study of the oxidation of arsenic (As) as aqueous As(III) to As(V) in the presence of flavins.

The Ecohydrology Research Group hosted a symposium on December 6, 2019 celebrating the research impact of Philippe Van Cappellen, his colleagues, and his current and former students. The full-day schedule included research seminars and lightning talks from researchers from over 15 institutions around the world.

Ecohydrology group PhD candidate Igor Markelov successfully defended his PhD thesis today titled: "Modelling biogeochemical cycles across scales: From whole-lake phosphorus dynamics to microbial reaction systems".

Ecohydrology PhD student Igor Markelov was part of a team that participated in the ETHWaterloo hackaton that took place in Waterloo on November 8-10, 2019. His team was selected as 1 of 5 winners out of over 60 submissions at the event.

A new publication entitled, “Sulfate Mobility in Fen Peat and Its Impact on the Release of Solutes”, considers the effects of subsidence and seawater intrusion on the decomposition of organic matter in coastal peatlands.
