Summary: Laminated polyester fabrics (geotextiles) can be used to apply thin layer sorbant materials followed by 15 cm of sand placement. A 1100 m^2 area, 1.1 to 5.6 m deep area in the Anacostia River was used to demonstrate this technology in 2004. Flow velocities ranged from 0.003 to 0.4 m/s and plots were contained in a silt curtain during placement. The technique did not lead to significant resuspension or recontamination of the placement area, with the exception of slight elevations of naphthalene. The mats could be placed at a rate of 100 m^2/hr with a crane and divers. Overall placement costs ranged from $29-33/m^2.
