I recently accepted a position as one of three Executive Editors for the journal, Groundwater. Working with the editor-in-chief, Leonard Konikow, we assign reviewers and make editorial decisions. My very first paper was published in Groundwater (Isotopes in Groundwater Investigations, in 1982), so I owe a lot to the journal for getting me off to a good start in publishing!
My reading list just got a lot longer, however.
