Description
Sampling of 3H and 4He environmental tracers from screened groundwater wells to constrain groundwater age distributions and validate numerical model predictions of mixing between modern and pre-modern groundwater.
Typical Equipment
- groundwater wells
- environmental tracer sampling equipment
Output Measurements
- 3H concentrations
- 4He concentrations
- groundwater age constraints
