Research and projects
Our research is grouped under several overlapping themes :
- Natural attenuation of pollutants
- Restoration science and practice
- Biogeochemical processes
- Catchment science and management
These themes integrate multidisciplinary experimental research and engineering applications through laboratory, field and modelling studies. Details of individual research projects both current and closed can be found by following the project portfolio links below.
Natural attenuation of pollutants
Natural attenuation is the risk-based management of contaminated land and groundwater using the combined effects of biological, chemical and physical processes, which occur naturally in the subsurface environment. This approach is founded on a fundamental understanding of the in situ processes in the subsurface, proven methods to monitor their occurrence and appropriate technical frameworks to interpret their performance. The GPRG has an extensive track record of research and technology innovation in this field, including the development of advanced performance assessment models. The group collaborates with numerous international research teams in progressing the practical application of this scientific field.
Restoration science and practice
There is a increasing acceptance of risk based solutions and the importance of developing sustainable remediation strategies for the management of soil and groundwater contamination. However, the development and validation of new and improved remediation concepts and technologies to achieve desired performance and clean-up objectives remains a technical challenge. The GPRG undertakes fundamental and applied research to develop innovative remediation concepts in this field, collaborating extensively with industry partners and leading international research teams. The group has specific expertise in bioremediation concepts for in situ and ex situ applications, and development of "Green Remediation" approaches.
This research field is focused on improving our understanding of interactions between microorganisms and the natural system in subsurface environments, and how this affects the fate of contaminants in soil and groundwater. Our research involves the study and interpretation of cellular interactions of microorganisms within the natural environment and chemical compounds (organic compounds, nutrients, metals and radionuclides), from the molecular-scale to the field scale. A key feature is the emphasis on multidisciplinary approaches, which integrate laboratory, field and modelling studies to provide a systematic and comprehensive understanding.
Catchment science and management
This research theme operates at the large scale where science is used to inform policy and practice of government, the Environment Agency and local government. The GPRG works closely in this field with the Catchment Science Centre.
