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
PAM Used To Reduce Erosion From Rainfall And Irrigation
Similar Soil Erosion Problems
Polyacrylamide Types
1. Emulsion
2. Granular
3. Gel Block
Site Specific Soil/Water Test Needed To Ensure Performance
Must Have Documentation Of Toxicity Testing

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

•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
