Isotope Studies.
- Stable isotope studies (deuterium and oxygen-18) of surface water and groundwater.
- Studies of origin and residence time of groundwater (tritium, carbon-14).
- Studies on origin and biogeochemical processes of sulfate (sulfur-34 and oxygen-18).
- Tracer tests with isotope tracer.
- Design of early alert systems of contact water infiltration, based on isotope monitoring.
- Liner failure detection and monitoring.
- Support for karst studies.
