The contamination comes from a variety of industries that have been operating in the area for more than a century, including chemical manufacturing plants, scrap metal recycling, log transfer facilities, and shipbuilding. But the waterway is now becoming recognized as one of the most successful large-scale dredging cleanup operations ever attempted, thanks in part to Geotube® dewatering technology.
