This picture is great because it gives us a chance to see the cloudy water (silt/sediment) within the Floating Turbidity Barrier. And it also allows us to see the clean and clear water on the exterior of the curtain. Please note that this product was designed to serve this very purpose. Confine any silt and sediment within a work area, while keeping the water outside of the work area clean, clear and free of any silt and sediment. The water is so clear on the outside of the curtain that we can practically see the bottom of the yellow curtain.
