David Nelms is the Groundwater Specialist for the U. His studies have dealt with fractured-rock and karst aquifers, groundwater/surface-water relations, water budgets, age dating, aquifer susceptibility, groundwater contamination, hydroseismicity, and land subsidence.
Some sand-and-gravel aquifers in Oswego County contain mixtures of old and young water.
Wellhead-protection efforts need to focus on protection of the quality of young water in the sand-and-gravel aquifers because young water is more likely to be contaminated than old water.

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.
