• LA9. Integrated Services for the Geoenvironment

Coordination: Orquídia Neves, IST
Co-coordination: Mª Rosário Carvalho, FCUL
Institutions: FCUL, IGOT, IPCB, IST, LNEG, UA

Action line that promotes the integration of several working groups for the provision of services in geoenvironment, contributing to the sustainability of geological resources.

It aims to identify and enhance the use of C4G resources necessary to perform integrated services in Geoenvironment, through the identification, characterization and monitoring of geoenvironmental parameters.

Report with the plan and the best locations for monitoring.

  • Monitoring of geoenvironmental parameters
    Sampling and monitoring the spatio-temporal variation of the physical chemical parameters (eg. pH, electrical conductivity, dissolved oxygen, salinity, Eh, anions, cations), or mechanical (eg. simple compression resistance, friction angle…), evaluated in sampling under study (eg, waters, soils, sediments, plants and rock masses).

    Delimitation of the protection areas for groundwater abstraction from contamination, with resources for hydrogeological studies, analytical methods and numerical methods of flow modeling and transport of contaminants. Consultancy, to be evaluated on a case-by-case basis.

  • Definition of protection and recharge areas of aquifers
    Mapping of areas susceptible to aquifer contamination and areas of potential infiltration leading to aquifer recharge. Consultancy, to be assessed on a case-by-case basis.

  • Geoenvironmental characterization through the use of environmental isotopes (stable and radioactive)
    Use of environmental isotopes (2H, 13C, 18O, 3H and 14C) to identify carbon origin in aqueous systems; in the definition of the preferential recharge altitudes in aquifer systems;  in the determination of the apparent speed of groundwater flow; in the identification and quantification of mixtures between different water units; in the identification of salinization mechanisms in groundwater and, in groundwater dating (transit time, definition of flow lines, etc.).
