Short description: The Report describes nitrogen attenuation and cycling processes in the subsurface environment. The report reviews the current state of knowledge on N-cycling processes in aquifers and sediments. It should be of interest to those assessing the attenuation of N in groundwater catchments and along river corridors. 
Long description: Nitrate is commonly thought of as behaving conservatively in the sub-surface environment but under certain circumstances it undergoes a microbially mediated transformation to nitrogen gas (denitrification). This process can be critical for protecting drinking water supplies and surface waters. This report provides a literature review of nitrate attenuating mechanisms as they occur in the sub-surface environment. It discusses the chemical conditions under which attenuation occurs and the hydrogeological environments within which this has been observed. It includes a review of the use of riparian buffer zones for managing nitrogen fluxes to rivers.
