A 5-year study and demonstration project, Assessment and Remediation of Contaminated Sediment (ARCS), emphasizes the removal of toxic pollutants from bottom sediments. Information from the ARCS program is to be used to guide the development of Remedial Action Plans (RAPs) for 42 identified Great Lakes Areas of Concern (AOCs) as well as resource management plans. The AOCs are areas where serious impairment of beneficial uses of water or biota (drinking, swimming, fishing, navigation, etc) is known to exist, or where environmental quality criteria are exceeded to the point that such impairment is likely. Among the hazardous materials detected from sampling of sediments are heavy metals, pesticides, various chemicals and industrial wastes. Industrial land use, runoff from watersheds, landfills, waste disposal practices and ground water flow contributed to pollutants found in bottom sediments of rivers and waterways channels.
