There are Safer Alternatives
Geotubes are large fabric sacks that allow dredge spoils to be contained and the runoff to be treated. Contaminated spoils are loaded into one of these sacks, which look like a huge sock laying on its side, and use gravity to allow water to seep from the bottom where a collection system catches the water and treats it. Dewatering is one of the most difficult, expensive and dangerous operations in cleanup. Geotubes allow this process to happen naturally using gravity, while the materials are fully contained. Once these gigantic sacks are dried and the contaminated water treated they are carted off to an appropriate landfill and the land occupied by the Geotubes, can be restored to its earlier use.
