Natural Attenuation of Nitrogen in Groundwater Discharging through a Sandy Beach

Changes in horizontal nitrogen (N) concentrations in predischarge groundwater were sampled in a profile of nutrient contaminated groundwater in a shallow sandy beach next to Cockburn Sound, W.A. from November 2004 to August 2005.

The degree of mixing and transport in the groundwater, and how this affected groundwater N concentrations, and whether these effects varied with changing seasons were measured.
