Data was collected from three wet detention ponds in Wilmington, NC, over 29 months, with varying drainage areas affecting water quality outcomes.
One urban pond showed significant reductions in pollutants like nitrogen and phosphorus, attributed to its design and diverse aquatic plant life, while another urban pond reduced turbidity but not nutrient concentrations due to suburban runoff disrupting the process.
The golf course pond had increased nutrient levels in its outflow, likely due to fertilizer use, but still performed better than other golf courses due to passing through a wooded wetland after discharge; emphasizing the need for optimal wet pond design to enhance pollutant removal.
