• Groundwater - Water residence times and turnover rates in aquifers
  • Streamflow - Water transit times and flowpaths in catchments
  • Integrated freshwater systems – Nutrient sources and forecasting
  • Drinking water vulnerability assessment based on age dating*
  • Interpretation of age and source indicators – Tritium, Carbon-14, Stable water isotopes, CFCs, SF6 , Chemical constituents
*Residence time in the ground is one of the criteria for demonstrating groundwater security (Drinking-water Standards for New Zealand: 2000 (DWSNZ:2000)).
