Project description

Dredged material management options for Great Lakes commercial ports are diminishing. Many existing disposal facilities 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. Given the declining placement capacity, use or recycling of ‰ÛÏnon-toxic‰Û dredged materials for beneficial use emerges as the most practical approach to sustainable dredged material management in the region. Considering the quantity of dredged materials (over 3 million cubic yards annually), beneficial use in transportation systems construction makes sense since it is one of the most material-intensive construction sectors. As a first step, identification of dredged material sources, suitable use applications in the transportation sector, and required material characteristics for suitability is needed. This information can be used to develop a map of dredged materials sources relative to various transportation applications. This information can also be directly piggy-backed onto previous source identification/mapping efforts (e.g., Great Lakes Commission and USACE efforts) to refine that information specifically for beneficial use of dredged materials in the transportation sector. Such information will be an important resource to beneficial use interests such as material suppliers, transportation agencies, and others.
