Contaminated Sediment Management

Pesticides, heavy metals and other toxic substances that are released into the air, land and water are deposited in the sediments that line lakes, rivers estuaries, and harbors. These toxics substances can remain for prolonged periods. In some organisms, the concentration of contaminants can increase if they absorb the substance at a rate faster than that at which it is excreted. This poses significant health risks higher up the food chain. EEMS has extensive proven capability in supporting industry and regulators in developing defensible models of these contaminated waterbodies.
