Contaminated sediment sites

Contaminated sediment sites are areas in lakes, rivers, or ponds where harmful substances, such as chemicals or heavy metals, have settled and accumulated in the底, or bottom layer. These pollutants often result from industrial discharges, runoff, or past waste disposal practices. Over time, the contaminated sediments can pose risks to aquatic ecosystems and human health if disturbed or if pollutants leach into the water. Managing these sites involves evaluating contamination levels, preventing exposure, and sometimes removing or treating the sediments to restore environmental quality.
