Rhine River, Rotterdam Holland
In 1992 a treatment program was done on the Rhine River in Rotterdam Holland. In that case we were cleaning up TPH waste from a Shell refinery. Bugs were applied upriver from the refinery and allowed to flow down river cleaning the river bottom sludge as well as the oil that was in the river.
The project continued for over two years and removed 90% of the oil from the water & 75% of the oil from the sludge in the river bottom.
