Environmental dredging is a process used to remove contaminated sediments from bodies of water, such as rivers, lakes, and harbors. This technique aims to improve water quality and restore aquatic habitats by carefully excavating polluted materials without disturbing the surrounding environment. The dredged materials are often tested and treated to minimize the release of harmful substances back into the water. Environmental dredging is commonly employed in areas affected by industrial activities, where pollutants like heavy metals and chemicals have accumulated over time, posing risks to both wildlife and human health.
