“…restoring about 1,300 acres of oyster reef would be about the same as building a state-of-the-art water treatment plant. That may sound like a lot, but there are many thousands of acres in the Bay that could potentially support restored oyster reefs.
That result stirred considerable excitement. Under the Clean Water Act, communities must reduce the amount of nitrogen flowing into rivers and estuaries. Faced with the possibility of needing to build new water treatment facilities at the cost of hundreds of millions of dollars to get into compliance with the law, the idea of using oysters instead may well make economic and ecological sense.” (Here)
