Professor W Mike Edmunds: a pioneer in applied hydrogeochemistry and champion of international collaboration

Mike Edmunds was a pioneer in modern applied hydrogeochemistry, helping to develop geochemical tools and their application to managing water resources. In a career span- ning almost 50 years, Mike made major contributions to water resource science as well as pro moting the role of chemistry in solving groundwater problems and championing the need to incorporate science into policy. There can be few hydrogeologists who travelled so extensively in order to study the vast range of groundwater environments of the world. Mike ’ s contribution to water scie nce was recognised through the many accolades he received including the Whitaker Medal in 1999, the O.E. Meinzer Award in 2009, and the Vernadsky Medal in 2010.
