What is contaminated sediment?

0

Contaminated sediment is deposited soil material that contains chemicals, at concentrations that are hazardous to human or ecological health. In general, the state environmental agency establishes the concentration limits of hazardous chemicals typically found in marine sediments using U.S Environmental Protection Agency (USEPA) guidelines. USEPA guidelines are established by modeling the effects on human health and the environment using conservative estimates of anticipated exposure limits and uptake. Some marine sediments found in our industrial ports contain some elevated levels of contaminants but usually they exist at concentrations below the hazardous range and are therefore not a threat to human health or the environment. Before dredging occurs, the proposed dredged material may be sampled to determine if the sediment material contains contaminants above hazardous limits. If the material were determined to be contaminated, the regulatory agencies would require dredging and place
