| Abstract/Contents: | "The transport of phosphorus (P) from soils to surface waters is a major cause of eutrophication. Phosphorus is often the limiting nutrient preventing algal blooms to surface water, so any method to prevent runoff containing phosphorus to surface waters is environmentallly [environmentally] important. One potential solution to this problem is through the use of various industrial byproducts that are rich in P-sorbing minerals. These materials (phosphorus-sorbing materials; PSMs) are able to react with dissolved P and remove it from solution preventing transport. A P-removal structure was constructed on the property of Stillwater Country Club, Stillwater, OK, to test whether it could be effective in removing dissolved P from golf course runoff. Results of the study include: During the first five months of operation there were 54 total runoff events, the majority of which were irrigation-induced. Dissolved P concentrations in irrigation runoff originating from nearby putting greens were typically between 0.3 and 0.5 mg L-1, while rainfall induced runoff events were normally 0.5 to 1.3 mg L-1. After five months, the P-removal structure captured 25% of the total P load entering the structure. As expected, the removal efficiency of the structure was highest at the beginning (near 100%) then decreased with additional P inputs. Phosphorus removal efficiency was greater for the low-flow irrigation-induced runoff events compared to rainfall-induced events. A model was developed that can be used to determine how much of a particular P-sorbing material is necessary for removing a targeted P load at a particular site." |
