PRESENTER BIOGRAPHIES 

David C. Goss 

David C. Goss served as the Executive Director of the American Coal Ash Association from 

August 2002 until his retirement in February 2009. Previously he worked for Xcel Energy where 

he coordinated the ash management activities for nine coal-fueled power plants located in 

Colorado and TDOE’s Combustion Byproducts Recycled Consortium (CBRC). He has been 

active in the EPA’s Coal Combustion Products Partnership (C2

PP

2

) since its inception in 2003 and 

was the CCP industry representative to the Industrial Resources Council (IRC). Goss received 

his Bachelor of Arts Degree from the University of Denver and a Masters of Public 

Administration from the University of Oklahoma. 

Dr. Warren Dick 

Dr. Warren Dick is currently a professor at the School of Environmental and Natural Resources 

of Ohio State University. Warren grew up on a farm in North Dakota. He was a chemistry major 

as an undergraduate at Wheaton College in Illinois and attended graduate school at Iowa State 

University where he received his PhD in 1980 in soil biochemistry. Since 1980 he has worked at 

The Ohio State University in Wooster, OH. During a sabbatical year in 1991-1992, he worked at 

AgCanada in Ottawa, Ontario. 

Warren has been active in his profession and has served as Editor of the Journal of 

Environmental Quality (1995-2001) and Editor-in-Chief of the Soil Science Society of America 

(2000-2006) and the American Society of Agronomy (2009- present). He became a Fellow of 

both the American Society of Agronomy and the Soil Science Society of America in 1997. His 

research has focused on cycling of carbon, nitrogen and sulfur in soils. Warren has been active 

since about 1990 on research related to beneficial land application uses of coal combustion 

products. This has included using clean coal combustion products for mineland reclamation and 

flue gas desulfurization (FGD) gypsum for agricultural use. Warren teaches a course on Soil and 

Environmental Biochemistry and has advised more than 25 graduate students and a dozen 

visiting international scientists. He is on the Ohio Agricultural Research and Development 

Center’s speakers list and has given talks to numerous local, national and international 

audiences. 

Dr. L. Darrell Norton 

Dr. L. Darrell Norton is a Research Soil Scientist for the USDA-ARS National Soil Erosion 

Research Laboratory located on the campus of Purdue University, West Lafayette, IN where he 

also is a Professor in the Departments of Agronomy and Agricultural and Biological 

Engineering. He has been with the Laboratory since 1982 conducting research on various 

aspects of soil erosion related to physio-chemical interactions between soil and rainwater. The 

last 19 years he has been leading research in the Laboratory to evaluate various industrial 

byproduct materials for use in controlling erosion and managing water in agricultural production 

systems. Much of his research has focused on relatively clean high Ca and S containing 

materials from air purification systems from coal-fired power plants. Dr. Norton’s research team

conducted an award winning project that created an environmental friendly synthetic soil from 

composts of fly-ash, bottom-ash and bio-solids from a pharmaceutical plant for use in 

reclamation and re-vegetation of strip mined lands. Dr. Norton and co-authors including many 

of his PhD students have published more than 250 articles and technical reports and has been 

widely invited to present results of his research at Scientific Congresses all over the World. He 

has conducted projects and cooperative research with many Agencies in the USA and many 

International Research Institutions such as CSIRO, Australia, EMBRAPA, Brazil, UN-FAO, 

India, CAS, China, US-AID, Africa, BARD, Israel, and many University and Institutes in the 

USA and Europe. He holds a BSc. '75 and MSc. '76 from Purdue University and a PhD '81 from 

The Ohio State University. 

Dr. Rufus L. Chaney 

Dr. Rufus L. Chaney is a Senior Research Agronomist in the Environmental Management and 

By-Product Utilization Laboratory of the USDA-Agricultural Research Service at Beltsville, 

MD, where he conducts research on the fate, food-chain transfer, and potential effects of soil 

microelements. He obtained his B.S. from Heidelberg College, Tiffin, OH in 1964 (Chemistry) 

and his Ph.D. from Purdue University, W. Lafayette, IN (Biochemistry). He has conducted 

research with USDA-ARS since 1969 in varied laboratories and positions. His research includes 

studies on 1) plant uptake of metals and translocation to edible plant tissues; considers plant-soil 

interactions in microelement phytoavailability; 2) speciation of metals in plants and 

bioavailability to animals; 3) development of hyperaccumulator crops to phytoextract and 

recycle metals in contaminated soils; 4) bioavailability of lead and other metals in soils, 

biosolids, and composts directly ingested by animals; 5) development of "Tailor-Made Composts 

and Biosolids" to remediate Pb, Zn, Cd, Ni and other element contaminated soils including urban 

gardens; and 6) potential methods to reduce food-chain transfer or toxicity of metals in these 

organic resources and potential regulatory approaches to protect food safety and soil fertility. 

These areas of study make him especially qualified to conduct risk assessment for trace elements 

in agricultural environments. Since beginning his career in 1969, Dr. Chaney has 418 published 

papers and 255 published abstracts on these topics. He has cooperated with the USEnvironmental Protection Agency, the US-Food and Drug Administration, the Office of 

Management and Budget, and many States in preparing advice and regulations for utilization of 

biosolids and risk evaluation and remediation of metal contaminated soils. 

Dr. Malcolm Sumner 

Malcolm Sumner (Professor Emeritus) was a professor at the University of Natal, 

Pietermaritzburg and at the University of Georgia. He has edited 5 books including the 

“Handbook of Soil Science”. He is also the author/co-author of 2 books, 249 refereed papers, 41 

book chapters and 300 other publications. Some career accomplishments include: Fellow, Soil 

Science Society of America and American Society of Agronomy; Soil Science Society of 

America Research Award; American Society of Agronomy Werner L. Nelson Award; CSIRO, 

Australia Sir Frederick McMasters Visiting Fellowship; American Society of Agronomy 

Research Award; Honorary Doctor of Science, University of Natal; Soil Science Society of 

America International Award; Soil Science Society of America Distinguished Service Award. He 

has consulted with various agricultural enterprises, companies, mining houses, state and local
