Presentation Transcript

  1. Polyacrylamide (P.A.M.) Blends For Erosion, Dust, & Turbidity Control

  2. 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

  3. USDA Has Used PAM To: • Reduce Agricultural Erosion • Increase Soil Infiltration • Improve Crop Yield

  4. PAM Used To Reduce Erosion From Rainfall And Irrigation

  5. Similar Soil ErosionProblems

  6. Polyacrylamide Types 1. Emulsion 2. Granular 3. Gel Block

  7. Site Specific Soil/Water Test Needed To Ensure Performance

  8. Must Have Documentation Of Toxicity Testing

  9. Reedy Creek Improvement District (RCID) Field Test Of Polyacrylamide Test Site: I 4 & Osceola Parkway Interchange Project Summer 1999

  10. PAM Test Applications: • Raw Slope Stabilization • Turbidity Control Of Stormwater Discharge • Turbidity Control Of Dewatering Discharge • Dust Suppression On Dirt Road

  11. Raw Slope Stabilization Test

  13. PAM Flocculation: Good Settling & No pH Change

  14. Dust Suppression Using PAM

  15. Insert pic of fertilizer spreader applying PAM & water wagon pics

  16. PAM For Demucking

  17. PAM For Demucking

  18. Insert PAM/muck grassing test on I-4 pics

  19. Insert PAM/muck grassing test on I-4 pics

  20. Turbidity Control Of Dewatering Discharge

  21. FLOC LOG Used For Turbidity Control During Rain Events

  22. 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

  23. PAM Blends Assist BMPs Must Match PAM To Soil Type With Testing Toxicity Test Documentation
