ENVIRONMENT

  • Environmental diagnosis.
  • Soils and associated water characterization, including: site historical study; physical environment study; site activity conceptual model with possible contaminant presence and spatial distribution. Site investigation design, sampling and testing; site and laboratory works; pollution assessment; potential sources and the most appropriate remedial measures. Finally, in necessary cases, study and assessment of the most suitable clean-up method according to physico-chemical conditions of the place.
  • Environmental hazard assessment related to potential soil/water contamination. Valuing: pollutants, concentration, exposure and toxicity.
  • Substance reference level determination according to soil guideline values (SGVs), determining the maximum substance concentration in a soil and the potential risk for environment and health for a particular land use.
  • Soil background level (BL) determination, including: carthographic databases collection; geological formation grouping; mapping according to: lithology, slope, protected areas, industrial or urban areas, etc. Sampling design and analysis. Data processing and background levels determination.
  • Landfill design or control studies, including: location, geometry and site geological characterization. Slope stability studies related to construction and filling sequences. Earthworks estimation; site searching for surplus materials or deposits to extract sealing materials. Geotechnical surveys. Hydrological and hydrogeological site characterization. Existing landfill control studies: environmental assessment, monitoring network for groundwater quality control, setting of possible remedial measures.
  • Environmental impact assessment for projects, (civil and hydraulic works, mining, etc) throughout different phases. Including: project analysis; identification of potential impact actions; affected environment analysis; effects characterization; impact evaluation; environmental impact prevention; protective and corrective measures; environmental surveillance plan; impact public communication. Summary document. .
  • Environmental mapping at different scales according objectives.
  • Environment oriented GIS digitalized and georeferenced geographical information related to external databases. Data integration. Mapping of different theme updated inventories.
  • Previous hydrogeological research aimed to avoid aquifer impacts by actions or hazardous substances or to authorize their deposition or removing.
  • 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).
