Paper - colloids, slopes & streams

Colloids can be important for transfer of phosphorus (P) to groundwater (GW) and contribute to elevated P concentrations later delivered to surface water. The analysis of water quality data from hillslope locations revealed contrasting P levels, fractions and species between two catchments (Timoleague and Castledockrell) with different soil chemistry and land use.
