Polyacrylamide (P.A.M.) Blends For Erosion, Dust, & Turbidity Control
POLYACRYLAMIDE (P.A.M.) • Natural Gas Derivative 1940’s & 1950’s • Several Thousand “Kinds” Of PAM • Only Use Anionic PAMS (No Toxic Effects) • Super Long Chain Molecule Composed Of Acrylamide Subunits • Must Match PAM To Soil Type • PAM Enhances BMPs Not Replaces Them
USDA Has Used PAM To: • Reduce Agricultural Erosion • Increase Soil Infiltration • Improve Crop Yield
Polyacrylamide Types 1. Emulsion 2. Granular 3. Gel Block
Reedy Creek Improvement District (RCID) Field Test Of Polyacrylamide Test Site: I 4 & Osceola Parkway Interchange Project Summer 1999
PAM Test Applications: • Raw Slope Stabilization • Turbidity Control Of Stormwater Discharge • Turbidity Control Of Dewatering Discharge • Dust Suppression On Dirt Road

TEST RESULTS: • Significantly Improved Soil Retention On All Sites • Good Flocculation Results For Turbidity Control • No Apparent Toxic Results From PAM To Ecosystem • Easy Application Using Existing Equipment • Cost Effective • Easy To Keep On Site • Contractors Liked Floc Logs
PAM Blends Assist BMPs Must Match PAM To Soil Type With Testing Toxicity Test Documentation
