Anionic Polyacrylamide (aPAM) has been approved for use under the federal Construction General Permit (CGP) for over two decades and still many stormwater and erosion/sediment control practitioners are not aware of how, when or where to use this technology. This presentation will provide the fundamentals for using aPAM safely and effectively and highlight its appropriate use for dust control, soil stabilization and water clarification on three separate projects in Florida. The dust control case study is from a landfill adjacent to Disney World where fugitive dust was a major nuisance to the surrounding community. The soil stabilization case study was developed in conjunction with the Florida Department of Transportation and demonstrates how aPAM was used to stabilize a newly constructed highway project and held up under the destructive forces of a hurricane. Lastly, the session will review a construction project for a theme park attraction at Disney World where turbid discharges led to the project being shut down until they could get their discharge NTUs under 32. This case study will show how turbidity levels exceeding 400 NTUs and discharging into adjacent wetlands was treated with aPAM to achieve a discharge level of 12 NTUs, well within the targeted amount.
