Bold & Gold
What is it?[edit]
Bold & Gold is a biosorption activated media (BAM) for pollution control developed by the Stormwater Management Academy at the University of Central Florida. It can be used to achieve nitrogen and phosphorus reduction in stormwater, wastewater and agricultural applications such as retention basins, swales and rain gardens, urban gardens and soil cells, permeable pavements, green roofs, filter strips and more. Bold & Gold is composed of a patented blend of mineral materials, sand, and clay.
How is it being used?[edit]
Bold & Gold was used to remove total phosphorus in an urban on-line up-flow filter and an off-line filter in Florida (FDOT, 2014)[1]. It was also used in Florida in residential swales covered with native soil and sod to remove nitrogen and phosphorus from stormwater (FDOT, 2023)Cite error: Closing </ref> missing for <ref> tag
