Early data from the George Richardson site indicate a reduction in [[Total suspended solids]] and phosphorus after going through the system.<ref name=CVC/> "Average TP concentrations into the filter were 0.12 mg/L with a maximum of 0.54 mg/L as compared to an average outlet concentration of 0.052 mg/L with a maximum of 0.13 mg/L. Average soluble phosphorus (orthophosphate) concentrations into the filter were 0.01mg/L with a maximum of 0.031 mg/L as compared with an average outlet concentration of 0.007 mg/L with a maximum of 0.044 mg/L." <ref name=LSRCA/> Poor orthophosphate removal was observed during hypoxic or anoxic conditions because the iron/phosphorus bond that facilitates the removal of orthophosphate can be broken under low oxygen conditions.<ref name=LSRCA/>
