Slide 9 of 100
Notes:
This slide illustrates estimated sediment deposition rates of stormwater ponds and wetlands. Sedimentation is the primary pollutant removal mechanism in ponds and wetlands, and these data suggest that in-stream ponds and wetlands are less effective at promoting sedimentation than off-stream designs. While generally not as significant, biological uptake by plants and algae is another important pollutant removal mechanism in ponds and wetlands.
