Water

Water is essential to support life on Earth, is vital for humankind and also provides a useful energy resource.

Our research focuses on identifying the processes controlling the sources and cycling of carbon, nitrogen and phosphorus in surface aquatic systems and the inter-relationships between hydrology, land use and water quality in upland catchments, especially acidification and metal mobilisation.

Projects

We have generated new knowledge in using ochre (a waste material from treating polluting mine drainage) to remove phosphorus from sewage effluent and agricultural runoff and in the recycling of recovered phosphorus as an agricultural fertiliser. 

Our research has also contributed to assessing the effectiveness of sustainable urban drainage systems (SUDS) in remediation of urban runoff, particularly sedimentation and sediment quality in SUDS structures and improving understanding of the functioning of constructed wetlands for farmyard runoff and wastewater treatment, including the effect of different reed populations on treatment performance.

  • Quantifying methyl halide emissions from different ecosystems.
  • Biogeochemical cycling of trichloroacetic acid (a phytotoxicant) in the environment to determine whether it is derived from manmade (atmospheric oxidation of chlorinated solvents) or natural (in situ soil processes) sources.
