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

6 Similar Soil Erosion Problems

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

8 Site Specific Soil/Water Test Needed To Ensure Performance

9 Must Have Documentation Of Toxicity Testing

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

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

12 Raw Slope Stabilization Test

13 Insert pic of water wagon applying PAM

14 PAM Flocculation: Good Settling & No pH Change

15 Dust Suppression Using PAM

16 Insert pic of fertilizer spreader applying PAM & water wagon pics

17 PAM For Demucking

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

21 Turbidity Control Of Dewatering Discharge

22 FLOC LOG Used For Turbidity Control During Rain Events

23 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

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