Water resource management

Water is naturally tagged with isotopic “fingerprints,” which can be used to determine the source, age, movement and interactions of water above and below ground. This information provides a scientific basis needed for the sound management of water resources.

  • Groundwater

    Groundwater is the largest source of freshwater for mankind. Isotope techniques are used to determine the origin and replenishment rates of groundwater, obtained through the use of stable and radioisotopes naturally present in groundwater. Read more →

  • Rivers

    Rivers comprise less than one per cent of all available freshwater, yet are central to humankind for water supply, energy and transportation. Stable isotopes are powerful tracers to study river-groundwater interactions, assess aquatic nutrient sources and dynamics, quantify the water balance of watersheds and address sedimentation dynamics.

  • Water availability

    Stable and radioisotope tracers are used in large-scale hydrological studies as powerful tools to assess the amount and origins of water and whether the amount that is taken out is sustainable. These tools help map water resources and obtain precise information on its availability. Read more →

  • Water Quality

    Water quality

    The quality of water is often compromised as a result of human activities and infrastructure, making the very source of life a threat to life. Nuclear techniques can help source water quality stress factors and offer insight into how to keep water fit for purpose and remediate polluted water.  Read more →
