Floating Garden Cleans As It Grows In One of Most Polluted Waterways In US

The Gowanus Canal in New York City is notorious for being one of the most polluted waterways in the U.S. Imagine everyone’s surprise when, three weeks ago, an oasis of pure greenery sprouted atop the surface of the river.

Not only is this improbable garden a breathtaking sight on the brackish water, but it is also cleaning the stream as it blooms.

The project, called GrowOnUs, is an experiment in “floating infrastructure” that utilizes a process called phytoremediation to tidy up the murky canal. Over 30 different kinds of plants act as sponges to purify, desalinate, and mitigate the chemicals affecting the waterway.
