AEM Group has excellent experience providing sediment sampling and analysis services in the Great Lakes Watershed states of Michigan, Minnesota, New York, Illinois, Indiana, Ohio, Pennsylvania, and Wisconsin. Due to the nature of investigations, our professionals coordinate with a number federal, state, and local agencies assuring all the applicable requirements are considered for accomplishing objectives of the investigation.
USACE-Detroit District
Sediment Sampling of Duluth-Superior Harbor, Wisconsin and Minnesota
This project included sediment, surface water, elutriate, and benthic investigation of the St. Louis River and Duluth-Superior Harbor in Wisconsin and Minnesota. Our professionals conducted the following: delineation of contamination identified during earlier investigations; project management; reviewing contractor quality, quality assurances and quality control; subcontractor selection; preparing site health and safety plan; oversight of geoprobe and sediment sampling activities; data management, evaluation, and laboratory validation; surveying; mapping; report preparation, and correspondence with the USACE Detroit District, and the State of Minnesota regulators. Sediment and water samples were analyzed for dioxins, PNAs, PCBs, metals, nutrients, physical properties, and grain size. Sediment biological samples were analyzed for Chironomus dilutus, and Hyalella azteca.
