Abstract
Land disturbing activities during urban and suburban development are increasing soil erosion and leading to increasing turbidity in surface waters of Georgia. In two field trials, we tested the efficacy of low applications rates of polyacrylamide (PAM) for
reducing soil erosion on recently disturbed slopes of 15 and 35%. The total suspended solids (TSS) of runoff waters for treatments of PAM in combination with
hydroseeding were compared to hydroseeding alone or to controls. TSS of runoff waters from PAM with
hydroseeding or hydroseeding alone was similar and both treatments were lower than controls. All
treatments, however, showed >20-fold decreases in TSS with time. Currently, we are testing higher rate
applications of PAM as a potentially more effective means of reducing soil erosion.
