This greenhouse at the former historic Fisherville Mill in South Grafton, Massachusetts, sits on the banks of a canal by the Blackstone River.  It is cleaning stormwater runoff and water contaminated by #6 fuel oil, also known as Bunker C oil, which leaked from underground tanks.  At the end of the process, 95% of the hydrocarbons are removed without the application of chemicals, using only ecological design.

The Blackstone River can rightfully claim to be the birthplace of the Industrial Revolution in the USA as in 1790, Samuel Slater built the first water-powered spinning mill in America for Moses Brown, a founder of Brown University, in Pawtucket, RI using the Blackstone River as a power source.  By October 7, 1828, the Blackstone Canal from Providence, RI to Worcester, MA was completed and became the original industrial corridor of the United States.  Some say the Blackstone was the hardest working river of 19th century America with its water powering factories all along its length.

Perhaps now it will become an example of 21st century American technology that uses ecological systems thinking to clean up the wastes industrial development has left in its wake.
