Geochemical signatures associated with each TCE source zone were identified by examining spatial patterns in groundwater chemistry.
Groundwater ages were calculated using the tritium/helium-3 (3H/3He) dating method.
Professor Stute holds a concurrent position as Adjunct Senior Research Scientist at the Lamont-Doherty Earth Observatory and is a member og the faculty of Columbia's Department of Earth and Environmental Science.
Professor Stute teaches such courses as Environmental Data Analysis, Hydrology, Workshop in Sustainable Development and leads the joint Columbia/Barnard Senior Research Seminar, the capstone experience for our majors.
All Groundwater samples contained an excess of atmospheric noble gases (‘excess air’) usually with an elemental composition equal to air.
The concentrations of atmospheric noble gases in the groundwater were used to calculate the excess air component and the water temperature at recharge.
