Secondarily treated wastewater was applied separately to sandy and siltaceous soil-turf filters to study relative removals of phosphorus, sodium, boron, and chlorine and the associated implications for groundwater recharge. Removal of phosphorus was greater in the siltaceous filter, but in both filters leachate phosphorus concentrations increased with rate of wastewater application and with time; amendment of soils with lime may be necessary to keep leachate phosphorus concentrations low. That neither filter retained boron indicates potential problems may arise if wastewater borate concentrations increase. Sodium adsorption ratios were 3 to 4, regardless of application rate or soil type, and seemed to pose no hazard. Leachate chlorine was undetectable; however, high-pH-induced iron chlorosis could be harmful to turf.
