For years, sediment dredged from the bottom of the Buffalo River was considered so toxic it had to be hauled to a special disposal facility.

Now, after a $75 million cleanup, the sand, silt and gravel from the river is healthy enough to be used to build a new habitat for fish, shorebirds, turtles and other aquatic wildlife on Buffalo’s Unity Island.
