Abstract:

Unmanaged construction stormwater runoff can pose a risk for the quality of downstream water bodies. Temporary sediment control practices are designed to capture sediment particles and reduce the turbidity of discharge; however, commonly used practices have limited performance in capturing fine-sized sediment particles. Flocculants can be introduced to construction stormwater runoff to enhance the performance of sediment control practices by increasing the settling velocity of suspended materials. This research study explored practical methods to enhance guidance for proper selection, use, and application of flocculants in construction stormwater management through (1) a state of the practice survey, (2) soil assessments, (3) bench-scale experiments, (4) flume experiments, and (5) intermediate-scale flume and large-scale evaluations. In total, 14 different products were used for bench-scale experiments. Best performing products for unique soils were identified with a match test study, which ranked products based on their performance.
