“…The SGD input of phosphorus is massively inferior to its nitrogen and silicon contribution on a molar basis as a result of the differential mobility of phosphorus in soils compared to the other species (Appelo and Postma 1993). Contrary to N and Si, P has high adsorption affinity for calcium carbonates (Cole et al 1953;Freeman and Rowell 1981;House and Donaldson 1986;Isenbeck-Schröter et al 1993) and it is therefore unsurprising to see that P mobility is reduced within the Gort karst system. Indeed, phosphorus leeching from agricultural soils and septic tanks is effectively attenuated very close to the source input (Spiteri et al 2007).…”

“…Perhaps the most important of these uncertainties is the extent to which concentrations in samples collected from groundwater are maintained in transfers to the surface water receptor or wetland (House, 2003). These transfers may be affected by (1) adsorption reactions within the saturated zone (Isenbeck-Schröter et al, 1993;Stollenwerk, 1996); (2) processes within the riparian or hyporheic zone, which retain and/or release P depending on seasonally variable environmental conditions (Hendricks and White, 2000;Carlyle and Hill, 2001;Prior and Johnes, 2002;Griffioen, 2006); and (3) whether groundwater P enters the surface water body through discrete entry points (e.g. Howden et al, 2004) rather than diffuse inflow.…”

“…Reactive phosphate in the aquifer is mostly present as dissolved inorganic phosphate (Slomp and Van Cappellen, ) while little is known about concentrations of dissolved organic phosphate in groundwater (Kalbitz et al, ). Fast surface sorption of the dominant forms of phosphate, which are HPO 4 2− and H 2 PO 4 − , occur by anion exchange (Isenbeck‐Schröter et al, ; Ptacek, ; Robertson, ) onto positively charged mineral surfaces such as Al‐containing, Mn(IV)‐containing and Fe(III)‐containing oxides and (oxy)hydroxides, and calcite (e.g., Wilhelm et al, ; Ptacek, ; Zanini et al, ; Spiteri et al, ); onto clay surfaces by complexing with calcium, aluminium and iron (Loeb and Goldman, ; Ptacek, ); and onto solid organic carbon (Harman et al, ).…”
