AquaGate+PAC provides a means to place powder activated carbon (PAC) through the water to a contaminated sediment surface. This can be done with the material blended with other granular capping materials (i.e. sand) to achieve a uniform distribution within an 'Active Cap', or it can be placed alone in very thin layers to achieve a low impact, in-situ treatment to reduce the bio-availability of contaminants within the sediment.
AquaGate+PAC (Powdered Activated Carbon) is a patented, composite-aggregate technology resembling small stones typically comprised of a dense aggregate core, clay or clay-sized materials, polymers, and fine-grained activated carbon additives.

AquaGate+PAC serves as a delivery mechanism to reliably place reactive capping materials into aquatic environments.
