Constructed Wetland Filter Use for Controlling Nutrient and Sediment Runoff from Golf Course Developments
Interest in the control of pollution entering into waterways has risen significantly since the last quarter of 20th Century and golf course developments have been identified as areas that use some of the chemical pollutants found in these waterways. Runoff control of pollutants from golf course developments is vital in assuring clean waterway systems for the future. This study investigates the runoff issues that can be related to golf course turf grass systems and their control through use of wetland filters. Three issues addressed in this study are suspended sediment, nitrogen, and phosphorus levels contained in turf grass runoff. Sediment runoff levels were found to be low to moderate for turf grass systems, while nutrient transport in runoff from turf grass areas can become a significant problem. Constructed wetland filtration systems were investigated as one potential method for controlling turf grass runoff. The design and construction of these wetland filters was investigated to determine their potential for filtering runoff from golf course facilities. Data showed that significant levels of runoff sediment and nutrient pollution could be removed if proper design and construction processes are followed.
