To Sponge Up Gowanus Muck

Gowanus Canal pollution. It’s not only about the decades and decades of industrial toxins that poured directly into the waterway. As anyone who lives near the notorious channel can attest, human waste also fouls the canal after heavy precipitation. And what can’t be seen are the ground-level contaminants, such as heavy metals, that flow down the streets into the canal during downpours and heavy snow melt. When sewer mechanisms cannot handle the additional flow, this gunk goes straight into the canal as well.
