Donald Ira Siegel (born October 24, 1947 [1] ) is the emeritus Laura J. and L. Douglas Meredith Professor in the department of Earth Science at Syracuse University. [2] He served as the president of the Geological Society of America from July 2019 until June 2020. Siegel is known for his work in wetland geochemistry and hydrogeology.
Siegel earned his Bachelors in Geology at University of Rhode Island in 1969. He earned his MS at Penn State and PhD in Hydrogeology at University of Minnesota. [3] His 1981 PhD thesis was titled "Hydrogeochemistry and kinetics of silicate weathering in a gabbroic watershed, Filson Creek, Northeastern Minnesota". [4]
Siegel began his career at Amerada Hess Corporation in 1971 as an exploration geologist, conducting geological studies to locate oil and gas in the Rocky Mountains and southwestern United States. [5]
He moved to the United States Geological Survey in 1976 as a district hydrogeologist in the Minnesota District. [5] [6]
In 1982, he became an assistant professor at the College of Arts and Sciences at Syracuse University, becoming a full professor in 1992. Siegel was appointed department chair in 2013 and worked at Syracuse until his retirement in 2017. [7] He was also the Jessie Page Heroy Professor and a Meredith Professor of Teaching Excellence (2009). [8] [9]
While working as a USGS hydrologist, after making his early observations on deep groundwater deposits, Siegel discovered that groundwater flow regulates the diversity of habitats in the mires, world's largest wetlands. He also studied interaction of oil-spill organic matter with minerals in affected aquifers, interaction of this groundwater with wetlands, and the westernmost edge where acid rain was being deposited by coal-fired power plants. [10]
After joining the faculty at Syracuse, Siegel studied of how groundwater and deep saline waters passed through the Marcellus Shale millions of years ago to the present. Siegel's wetland research evolved into an examination of how groundwater flow and water quality influences greenhouse gas emissions in vast peat lands in northern Canada, Siberia, and northern Minnesota. His early study of groundwater contamination resulted in the closure of Staten Island's Fresh Kills Landfill. [10] [11]
Siegel also investigated the use of similar forensic techniques to characterize fluids generated by hydraulic fracking and other unconventional gas and oil extraction in western China, Pennsylvania, Ohio, and New York State. [10] [12] [13]
Siegel has said that hydrofracking benefits in New York state outweigh the environmental risks, [14] calling it a safe process. [15] [16]
In 2015, Siegel was involved in a conflict-of-interest controversy. [17] [18] [19] In a peer reviewed paper, Siegel came to a conclusion that natural-gas production using fracking wells had not contaminated groundwater in Pennsylvania and that methane in drinking water was unrelated to fracking. [20] [21]
After media reports that Siegel did not disclose that Chesapeake Energy, a hydrocarbon exploration company, had paid him to analyze the data, the journal Environmental Science & Technology, which published the analysis, posted a correction. [22] [23]
While fracking proponents praised the study, many environmental groups ethical violations and cited smaller sample size that had produced conflicting results. Despite Siegel's admission of private funding, he received intense backlash. Critics demanded that he be fired or retire from Syracuse University, and that an ethics investigation be launched by both SU and the journal. The university later found that Siegel was in compliance with University's internal disclosure policies. [24] In 2015, Siegel was called to testify before the Committee on Science, Space, and Technology in Washington, D.C. [25] [26] [27]
The Hydrogeology Division of the Geological Society of America selected Siegel as the 1993 Birdsall Distinguished Lecturer in Hydrogeology. [1] [28] He was elected and served as the 1995 Chairman of the Hydrogeology Division of the GSA. [5] He is a recipient of the Geological Society of American’s Distinguished Service Award. [10]
In 2005, Siegel received the Meinzer Award for Research by the Hydrogeology Division of the Geological Society of America. [6]
In 2010, Siegel was appointed chair of the Water Sciences & Technology Board for a three year term. [29] In 2012, Siegel was elected member of the American Association for the Advancement of Science for "his distinguished service and pioneering contributions on the hydrogeology and biogeochemistry of wetlands and contaminant transport". [10] [30] He was elected a fellow of the American Geophysical Union in 2013. [7]
Siegel served as the president of the Geological Society of America from July 2019 until June 2020. [31] [32] [33]
In 2022, he was awarded the Marcus Milling Legendary Geoscientist Medal by the American Geosciences Institute. [34]
Siegel was born on October 24, 1947, into a Jewish family in New York City. [1] He lives in Syracuse with his wife Bette Siegel.
In 2005, he wrote a cookbook titled "From Lokshen to Lo Mein: The Jewish Love Affair With Chinese Food" (Gefen, ISBN 9789652293572). [35] [36]
Dimock Township is a township in Susquehanna County, Pennsylvania, United States. The population was 1,232 at the 2020 census. It is the home of former U.S. Congressman Chris Carney, a Democrat who represented Pennsylvania's 10th congressional district from 2007 to 2011. The school building for the Elk Lake School District is located near the village of Elk Lake in the township.
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available freshwater in the world is groundwater. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology.
Hydrogeology is the area of geology that deals with the distribution and movement of groundwater in the soil and rocks of the Earth's crust. The terms groundwater hydrology, geohydrology, and hydrogeology are often used interchangeably, though hydrogeology is the most commonly used.

The O.E. Meinzer Award is the annual award of the Hydrogeology Division of the Geological Society of America. Established in 1965, it is named after Oscar Edward Meinzer who has been called the "father of modern groundwater hydrology". The Meinzer award recognizes the author or authors of a publication or body of publications that have significantly advanced the science of hydrogeology or a closely related field.
Fracking is a well stimulation technique involving the fracturing of formations in bedrock by a pressurized liquid. The process involves the high-pressure injection of "fracking fluid" into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants hold the fractures open.
Fracking in the United Kingdom started in the late 1970s with fracturing of the conventional oil and gas fields near the North Sea. It was used in about 200 British onshore oil and gas wells from the early 1980s. The technique attracted attention after licences use were awarded for onshore shale gas exploration in 2008. The topic received considerable public debate on environmental grounds, with a 2019 high court ruling ultimately banning the process. The two remaining high-volume fracturing wells were supposed to be plugged and decommissioned in 2022.
Environmental impact of fracking in the United States has been an issue of public concern, and includes the contamination of ground and surface water, methane emissions, air pollution, migration of gases and fracking chemicals and radionuclides to the surface, the potential mishandling of solid waste, drill cuttings, increased seismicity and associated effects on human and ecosystem health. Research has determined that human health is affected. A number of instances with groundwater contamination have been documented due to well casing failures and illegal disposal practices, including confirmation of chemical, physical, and psychosocial hazards such as pregnancy and birth outcomes, migraine headaches, chronic rhinosinusitis, severe fatigue, asthma exacerbations, and psychological stress. While opponents of water safety regulation claim fracking has never caused any drinking water contamination, adherence to regulation and safety procedures is required to avoid further negative impacts.
The environmental impact of fracking is related to land use and water consumption, air emissions, including methane emissions, brine and fracturing fluid leakage, water contamination, noise pollution, and health. Water and air pollution are the biggest risks to human health from fracking. Research has determined that fracking negatively affects human health and drives climate change.
