Technical Abstract: Subsurface tile drainage is essential in the construction and functionality of golf course greens. However, due to turf management, the waters conveyed by the drainage network contain potentially high levels of nutrients and pesticides. The objective of this research is to assess the subsurface hydrology and efficiency of different filter materials and in-line filter designs at removing or reducing the levels of pollutants in the discharge waters. In the laboratory, the filter materials significantly reduced the amount of phosphorus, chlorothalonil, and metalaxyl in the drainage waters. In the field studies, the results are mixed. Significant reductions in nitrogen species and total phosphorus were measured. Reductions in concentrations of dissolved phosphorus and chlorothalonil were noted; however, the reductions were not statistically significant.
