Research
My research focused primarily on groundwater flow and geochemistry in aquitards (confining units) of glacial origin (primarily till and loess). Within that broad framework, I investigated physical groundwater flow and chemical properties of groundwater in the till; using radioactive and stable isotopes to elucidate groundwater source and age; describe and quantify groundwater transport of agricultural chemicals in till, including the interaction of groundwater with lakes and streams and tile drainage; and examined the vertical integrity of the aquitards using anthropogenic tracers and aquifer tests.
