Characterization and risk assessment (Contact: Poul L. Bjerg)
Methods for characterization of pollution sources, redox processes, and contaminant distribution in aquifers and low permeability settings are developed and applied at contaminated sites. Methods for contaminant mass fluxes are developed and coupled to risk assessment at actual sites.
Soil and groundwater sampling and analysis (Contact: Peter Kjeldsen)
Methods and recommendations for sampling of soil and groundwater are developed. Chemical analysis for inorganic or organic compounds in soil, aquifer sediments and groundwater, and gas are developed or refined. Analyses are tailored to support experimental work in order to ensure high quality analysis and special needs in terms of small sampling volumes, complex matrixes or new types of contaminants.
Soil leaching tests for organic compounds (Contact: Peter Kjeldsen)
Groundwater risk assessment of contaminated soils should be based on a mobility assessment of the pollutants. Development of test methods to characterize the leaching of organic compounds from soils and ways of interpreting the results is carried out.
Food contamination (Contact: Stefan Trapp)
Uptake of contamination by crops is measured in lab and field tests and/or calculated by plant uptake models. For polluted soils in residential areas, food contamination often has the greatest impact on human health.
Toxicological testing of soil and groundwater (Contact: Poul L. Bjerg)
Toxicity tests are developed and applied to soil and groundwater samples collected at contaminated sites (e.g. gasoline spills, former gas work plants, and landfills). The biotests are used concomitantly with chemical analyses and both approaches are used in risk assessments and remediation of complex contaminations.
