1. A composite silt fence fabric configured to be coupled to stakes to form a composite silt fence, the fabric comprising:
a polymeric geotextile fabric particulate filtering layer extending substantially an entire width and length of the composite silt fence fabric and defining a hydraulic flow capacity for the silt fence, wherein the polymeric geotextile fabric particulate filtering layer is one of i) a nonwoven material and ii) a woven material;
a pollutant capturing layer coupled to the polymeric geotextile fabric particulate filtering layer and extending substantially the entire width and length of the composite silt fence fabric so as to substantially entirely overlay the polymeric geotextile fabric particulate filtering layer and configured to capture some select pollutants in water from flow that has passed through the polymeric geotextile fabric particulate filtering layer through absorption or adsorption; and
a backing layer coupled to the pollutant capturing layer extending substantially the entire width and length of the composite silt fence fabric so as to substantially entirely overlay the pollutant capturing layer.
