A Nationwide Survey on Flocculant Usage in Construction Stormwater Management

Billur Kazaz, CPESC IT

Flocculants are improving the performance of construction stormwater management practices by reducing stormwater turbidity. However, improper implementation of these chemical agents on construction sites may be hazardous to the environment. This study presents the perspective of state departments of transportation on flocculant usage by implementing a state-of-the-practice survey. The results of this survey will guide future research studies to improve flocculant implementation on construction sites by considering the perspective of the state agencies.

• Upon completion, participants will be able to learn about the flocculant usage in the United States among the state Departments of transportation.
• Upon completion, participants will be able to learn about the reasons for hesitating to utilize flocculants on construction sites from the Departments of Transportation perspective.
• Upon completion, participants will be able to learn about the commonly adapted flocculant implementation techniques, flocculant types, and dosage guidance methods by the state agencies.
