Abstract

Dredged material management options for Great Lakes commercial ports are diminishing. Many existing confined disposal facilities (CDFs) serving these ports are at or near capacity and high costs plus limited new site availability make prospects for new or expanded capacity increasingly unlikely. Restrictions on dredging have severe implications for freight movement in the North American midcontinent. Beneficial use (BU) of dredged materials as an alternative source of material for habitat restoration, earthworks, and transportation-related construction is emerging as a potentially attractive approach to sustainable material management in the region. This project builds directly upon previous efforts by the proposal team funded under CFIRE RI-8: “Beneficial Use of Dredging Materials from Harbors and Channels.” These previous efforts include planning of the recent beneficial use summit and development of a beneficial use technical framework. The proposed work plan is a natural extension of those efforts.

Objectives

The objective of this project is to advance the beneficial use of dredged materials as a sustainable material resource for construction operations in the Great Lakes region. Emphasis is placed on laboratory characterization of dredged materials from select confined disposal facilities (CDF) in Wisconsin, using this information to enhance web-based tools for dredged material management, and disseminating this information to a targeted audience of stakeholders in the region.

Tasks

  1. Lab characterization of dredged materials
  2. Enhancement of a web-based screening tool
  3. Dissemination and outreach of project results
  4. Final report
