CP080  Insitu Bioremediation for Contaminated Groundwater Waste Management
To reduce the impact of landfilling activities and agriculture on the aquatic environment, this project assessed the removal of nitrate from aquifiers by bioremediation.

The work examined natural denitrification attenuation properties of aquifers to provide a sustainable in situ method of contaminated groundwater treatment. A biochemical transport model was developed which, together with laboratory experimentation, was shown to minimise the cost to operators of assessing remediation strategies following entry of nitrate rich leachate into aquifers.

This project was approved by ENTRUST the regulator of Environmental Bodies under the UK Landfill Tax Regulations. The collaborators in the work were WRL (Project Management), Imperial College London, WRc, the UK Environment Agency, a Water Utility and the Drinking Water Inspectorate (DWI).

Benefits

A cost effective and sustainable treatment technology was produced for insitu remediation of groundwater polluted by ammoniacal-nitrogen (from landfills and agricultural sources). This is inline with the current environmental expectations of the European Community.
