Keep Sedona Beautiful will hold our next Preserving the Wonder Speaker Series event on Wednesday, November 15 at 5:00 pm. This month’s speaker is Dr. Tom Ginn, Environmental Toxicologist. His topic will be “Sedona Water – Sources, Discharges and Quality.”
In Arizona, it’s surprisingly difficult to understand where our water comes from, how much may be available, and what happens to it after it leaves our homes and apartments. Dr. Tom Ginn will present an overview of Sedona’s water supply and the current methods for returning treated wastewater to the environment. He will describe the groundwater aquifers that supply our municipal water and the sustainability of that source for future supply. Dr. Ginn will also discuss the issue of naturally occurring arsenic in our water supply. The presentation will also include a description of Sedona’s Wastewater Treatment Plant, including a discussion of the current disposal options for treated wastewater. Dr. Ginn will also present his recommendations for future wastewater disposal alternatives.
Dr. Tom Ginn is a retired water quality scientist and environmental pollution specialist with a 50-year career working on major sites throughout the U.S. He has served as an expert witness in major environmental lawsuits including wastewater treatment options for San Diego, PCB remediation in the Hudson River, PFAS sources in the Mississippi River, and metals pollution at many mining and smelting sites in the western states. In Sedona, Dr. Ginn is active in the OLLI Program at Yavapai College (Osher Lifelong Learning Institute) where he has taught many workshops and courses on a wide range of environmental Issues. He presented a fascinating discussion on “The Role of Nuclear Power in Our Energy Future” a year ago at KSB.
