Characterizing Sediment from Active Road Construction Sites in Central Ohio

Alec Grimm – Graduate Student, The Ohio State University

This presentation will compare runoff quality on active road construction sites and the performance of inlet protection products (IPP). Thirty IPP were evaluated using a full scale testing approach on four mock road sections with varying inlet configurations. Products were evaluated based on sediment removal capacity, ability to reduce or eliminate ponding behind the product, cost, ease of installation, product availability, and maintenance frequency. The goal of this project was to provide a standard specification for IPP performance testing in Ohio and allow for direct comparisons of performance in further IPP testing.

Learning Objectives: 

  • Understand the dynamic nature of stormwater runoff on road construction sites.
  • Develop a basis for evaluating the performance of sediment and erosion control products on road construction sites.
  • Understand improvements that can be made to current inlet protection products in order to improve water quality, longevity, and overall performance.

Alec Grimm is a graduate student under Dr. Ryan Winston at The Ohio State University in the department of food, agricultural, and biological engineering. His research focuses primarily on water quality, urban hydrology, and the performance of sediment and erosion control products used on active road construction sites. Prior to attending graduate school, Mr. Grimm received his B.S. in Environment and Natural Resources from The Ohio State University where as an undergraduate, researched potential pre-treatment devices for stormwater control measures.
