Ralph Turner, Ph.D., P.G.
Environmental Chemist - Associate
Dr. Ralph Turner has diverse experience spanning more than 30 years in the field of biogeochemistry of terrestrial and aquatic ecosystems. After completing his PhD in 1975, Ralph became a researcher in the Environmental Sciences Division of Oak Ridge National Laboratory (ORNL), Oak Ridge, Tennessee. During his 22-year tenure at ORNL he conducted extensive research and characterization at two large mercury-contaminated sites: a defunct chlor-alkali plant and a nuclear weapons plant. In 1997 he joined Frontier Geosciences, a specialty research and analytical services company in Seattle, Washington. In February 2000, Ralph formed his own company, RT Geosciences Inc., in Squamish, BC. Consultant activities with this company include project planning (mainly sampling and analysis) as well as the conduct of special field and laboratory projects. These special studies have focused particularly on mercury (Hg) contamination; examples include Hg treatability studies, measurement of soil and water fluxes of Hg vapor, sediment pore water extraction and analysis, dendrochemistry to reconstruct historic atmospheric Hg releases, building decontamination, Hg immobilization studies, soil/sediment Hg speciation studies, thermodynamic modeling of Hg behavior, and groundwater tracing study using dye and fluoride. For one of the major environmental remediation projects in BC (the Squamish Hg chloralkali site) he was the Environment, Health and Safety Manager. Ralph has served on numerous expert panels related to mercury in the environment. Between 2001 and 2004, he served on a panel concerned with mercury in sediments in the St Lawrence River near Cornwall, Ontario. Currently, he is a member of expert panels concerned with mercury in the Shenandoah River system in Virginia and East Fork Poplar Creek in Tennessee.
Through RT Geosciences, Ralph has been an Associate of Azimuth since 2005, for his work in Canada.
