Ground-water age dating in community wells in Oswego County, New York
Stephen C. Komor
2001, Open-File Report 2001-232
Officials in Oswego County, in north-central New York, have been concerned about potential contamination of community wells. Many of these wells are completed in unconfined glacial sand-and-gravel aquifers, although some are finished in till or in the underlying fractured and jointed bedrock of Late Ordovician and Early Silurian ages.

Art F. White, Alex E. Blum, Marjorie S. Schulz, Thomas G. Huntington, Norman E. Peters, David A. Stonestrom
2001, Book chapter, Water-Rock Interactions, Ore Deposits, and Environmental Geochemistry: A tribute to David A. Crerar
Present-day elemental and mineral weathering rates based on solute fluxes are compared quantitatively to past long-term rates determined from solid-state elemental fractionation in a saprolitic granite regolith at Panola, Georgia, USA. Saturated fluid flow across a low-permeability kaolin duripan controls the rate of steady-state unsaturated flow in the underlying saprolite....
