Intro
John H. Williams has a BA in Geology from Colgate University, and a MS in Geosciences from Pennsylvania State University. John currently is the Groundwater Specialist for the U. S. Geological Survey Water Science Center in New York, and is responsible for technical oversight of the Survey’s groundwater program in the State.
John has provided technical assistance to the U. S. Environmental Protection Agency, Army Corp of Engineers, and U.S. Nuclear Regulatory Commission on investigations of contaminated fractured-bedrock aquifers. He has worked with the Geological Survey of Canada in the investigation of transboundary aquifers in New York and Quebec.
In addition, John is an integral part of the geophysical training and technology transfer program of the Hydrogeophysics Branch of the Earth System Processes Division. He has provided support in borehole geophysics to Survey offices throughout the U. S. and in the United Arab Emirates. He recently co-taught a borehole geophysics workshop in northern Iraq for the Iraqi Central and Kurdish Regional Governments that was supported by the U. S. Department of Defense.
Over the past several years, John has made presentations on water-resource issues related to shale-gas development to the U. S. Department of Energy, U. S. Environmental Protection Agency, National Ground Water Association, North American Energy Marketers Association, Empire State Water Well Drillers Association, New York State Department of Environmental Conservation, Pennsylvania Department of Environmental Protection, professional associations of geologists, geophysicists, and engineers, universities, and environmental groups. He also has provided testimony to the New York State Assembly and New York City Council on these issues.

Geohydrology and Water Quality of the Northern and Central Parts of the Tug Hill Glacial Aquifer, Jefferson and Oswego Counties, North Central New York
Problem - The entire Tug Hill glacial aquifer is a 47-mile-long, crescent-shaped mixture of glacial deposits of predominantly sand and gravel on the western side of the Tug Hill Plateau in Jefferson, Oswego, and Oneida Counties in north central New York. The Tug Hill aquifer can be divided into three parts (northern, central, and southern) based on geohydrological setting, depositional history, anHydrogeology of Two Areas of the Tug Hill Glacial-drift Aquifer, Oswego County, New York
Problem - Several supply wells in Oswego County were evaluated by the USGS in 1999 by using stable oxygen and hydrogen isotopes and chlorofluorocarbon (CFC) age dating techniques. For two municipal well sites (the Villages of Sandy Creek and Lacona, and the Village of Pulaski) that tap a shallow, unconfined aquifer (typically 20-50 ft thick) there were significant discrepancies between ground-wateHydrogeology of the Virgil Creek Valley in the Town of Dryden, Tompkins County, New York
Problem The Village of Dryden, rural homeowners, farms, and businesses in the Virgil Creek Valley tap several confined sand and gravel aquifers in the Virgil Creek valley in the town of Dryden . The valley contains a large moraine with complex stratigraphy consisting of continuous and discontinuous layers of till, lake deposits, and glaciofluvial sand and gravel.

Groundwater-level analysis of selected wells in the Hoosic River Valley near Hoosick Falls, New York, for aquifer framework and properties
The U.S. Geological Survey, in cooperation with the New York State Department of Environmental Conservation, analyzed groundwater levels, drilling record logs, and field water-quality data from selected wells, and the surficial geology in the Hoosic River valley south of the village of Hoosick Falls, New York, to provide information about the framework and properties of a confined aquifer.

Evaluations of the lithostratigraphy, lithofacies, paleontology, ichnology, depositional environments, and cyclostratigraphy from 11 test coreholes were linked to geophysical interpretations, and to results of hydraulic slug tests of six test coreholes at the Snapper Creek Well Field (SCWF), to construct geologic and hydrogeologic frameworks for the study area in central Miami-Dade County, FloridaAuthorsMichael A. Wacker, Kevin J. Cunningham, John H. WilliamsObservations from borehole dilution logging experiments in fractured crystalline rock under variable hydraulic conditions
Identifying hydraulically active fractures in low permeability, crystalline-bedrock aquifers requires a variety of geophysical and hydrogeophysical borehole tools and approaches. One such approach is Single Borehole Dilution Tests (SBDT), which in some low flow cases have been shown to provide greater resolution of borehole flow than other logging procedures, such as vertical differential Heat PulAuthorsPhilip T.

In situ chemical oxidation (ISCO) treatment with sodium permanganate, an electrically conductive oxidant, provides a strong electrical signal for tracking of injectate transport using time series geophysical surveys including direct current (DC) resistivity and electromagnetic (EM) methods. Effective remediation is dependent upon placing the oxidant in close contact with the contaminated aquifer.AuthorsPhilip T. Harte, Thor E. Smith, John H. Williams, James R. Degnan - Software
