HYDROGEOLOGY (+)

  • Groundwater vulnerability assessment to pollution by human activities. Evaluation of isolated/diffuse contaminants that can be poured on the aquifer in a controlled or uncontrolled way. Environmental assessment for civil works, mining, etc.
  • Previous hydrogeological research aimed to avoid aquifer impacts by actions or hazardous substances or to authorize their deposition or removing.
  • Delineating groundwater protection areas for groundwater catchments which supply more than 50 people populations or for natural mineral waters and spa catchments.
  • Aquifer vulnerability assessment using hydrogeological, statistical, mathematical or parametric approaches, specifically, assessment of aquifer pollution vulnerability in landfills and large linear works or assessment of diffuse pollution (sea intrusion and nitrate content mainly).
  • Regional hydrogeological studies. Aquifer or aquifer system description and characterization: dimensions, hydraulic parameters, hydrodynamic performance, water quality, uses, hydric balance or resource availability.
  • Hydrogeological mapping at different scales according objectives: general or specific maps (particular ion concentration, water uses, water flow, physical-chemical water characterization, exploitation potential, etc
  • Hydrogeology oriented GIS, digitalized and georeferenced geographical information related to external databases. Data integration. Mapping of updated inventories, piezometry, hydrochemical values, etc.
  • Geophysics applied to hydrogeology. Aquifer surface investigations or borehole logging to know physical parameters (permeability), chemical water quality, hydrodynamic performance, or to carry out a proper borehole installation (correct location for grilles and filters).
  • Hydrogeological investigations for water extractions in supply, irrigation or industry, including previous location study, site investigation design, management and supervision, design of borehole/wellhead equipment (casing, grillage, prefilter, etc) and design, management, supervision and analysis of pumping test.
