Sediment Management

Hull has worked as a premier engineering and consultant firm in contaminated sediment management since the 1980s. Our team has significant experience working on large, multi-faceted remediation and restoration projects. We have worked closely with the U.S. Army Corps of Engineers to obtain permits, identify opportunities for alternative sediment management and beneficial use of materials.

Hull participates in multiple industry task forces, including the Great Lakes Dredging Team, Western Dredging Association – Midwest Chapter, and the Sediment Management Working Group. We closely follow programs and activities managed by the Lake Erie Commission, the International Joint Commission, numerous NGOs, and locally-based efforts to address Areas of Concern and Sustainable Dredged Material Management Plan. We also served as an appointed peer reviewer of the current USACE wetland delineation manual.

Hull’s services include characterizing sites and materials, completing human health and ecological risk assessments, developing sampling and remedial plans, overseeing remedial activities, completing post-remedy operations and maintenance-related tasks, and completing documentation and reporting throughout project completion. Remediation and restoration experience includes in-situ, as well as ex-situ sediment remediation for RCRA, CERCLA, and CWA 404/401 program requirements. We have completed multiple upland and in-water beneficial use of dredged material projects to address brownfields, agricultural, and construction product uses and to facilitate habitat restoration.
