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

Polyacrylamide Types

1. Emulsion

2. Granular

3. Gel Block

Site Specific Soil/Water Test Needed To Ensure Performance

Must Have Documentation Of Toxicity Testing
