Short description: Remediation of Agricultural Diffuse NITRAte Polluted Waters through the Implementation of a Permeable Reactive BARrier 
Long description: NITRABAR is a passive system for the removal of nitrates derived from past and present agricultural practices. Essentially, the system is a narrow trench, installed between the field and a water body, which is filled with a mixture of natural materials. As groundwater, runoff and field drainage waters pass through the system the nitrates are converted to nitrogen gas by mirco-organisms which attach themselves to, or live in between, the materials. It is expected that this approach will achieve an 85% reduction in the nitrate level in waters passing through the system. The project aims to demonstrate the application of the NITRABAR system in the agricultural setting and enable others to replicate the system throughout Europe. The system will be installed at the ecos millennium environmental centre, Ballymena, Northern Ireland. The project started in December 2005 and runs until March 2009. In the first year, the project team will be obtaining informaiton from the demonstration site to assist the design and positioning of the system. The system itself will be installed by the end of the first year. This will then be intensively monitored for two years to provide sufficient information to demonstrate its effeciveness over the various seasons.
