Dredged Material Management

We have demonstrated expertise in the evaluation of the physical, chemical, and biological characteristics of sediment for assessment of placement options. Our expertise extends well beyond sampling and analysis to include interpretation, evaluation, and management recommendations for placement options, beneficial use, and innovative reuse.  For decades, EA has provided scientific data and environmental documentation to support dredged material management and planning initiatives for maritime clients and in-water projects.
