Dredged Material Management

TestAmerica's Comprehensive Dredged Material Management Support

Several hundred million cubic yards of sediment are dredged from U.S. ports and waterways annually to maintain navigational channels and facilitate commerce, national security and recreation.

The regulations for dredged material disposal in U.S. waterways and oceans are complex, and are managed jointly by the U.S. Army Corps of Engineers (USACE) and EPA.  The USACE and EPA, in conjunction with a number of states, have developed guidance documents to support the decision making associated dredged material management.  To support this decision making process, TestAmerica supports chemical and physical environmental testing to aid in the evaluation of the potential environmental impacts of dredged material discharges.  

Potential dredging sites vary in their size and complexity. Dredged material evaluations often involve more than one environmental matrix, which can included sediment, surface water, elutriates, leachates, and tissues.   TestAmerica has extensive experience providing chemical and physical testing services in support of dredged material evaluations projects nationwide. These projects have been executed with oversight from various EPA Regions, USACE Districts, and state agencies. Guided by industry leading expertise and unmatched laboratory capacity, TestAmerica’s goal is to generate chemical and physical testing data to meet project specific objectives, thereby facilitating appropriate dredged material evaluation decisions.

How Can TestAmerica Help You?

TestAmerica’s 20 years of dredged material experience has consistently demonstrated that the critical factor for project success involves a dedication to pre-project planning, including Quality Assurance Project Plan review, with a detailed review and evaluation of targeted reporting limits for each project. TestAmerica has the experience, resources and desire to continue to support each project team’s goal, achieving mutual success in the execution of dredged material evaluation testing projects.

Chemical Testing

TestAmerica follows EPA methods and USACE procedures to evaluate dredged material samples for various contaminants of concern. Our chemical testing program supports matricies such as sediments, site water, elutriates, leachates and tissues.

Physical Testing

Physical, or geotechnical testing, is performed as a fundamental part of the dredged material evaluation process to support the characterization of sediment samples. TestAmerica offers comprehensive geotechnical services supporting sediment and dredged material evaluations utilizing ASTM Standards.

Elutriate & Leachate Generation and Column Settling Tests

TestAmerica supports all industry recommended elutriate and leachate generation procedures, as well as column settling tests required under the Ocean Testing Manual, Inland Testing Manual, Upland Testing Manual and various state guidance documents.
