An innovative history of American water-ways describing the symbiosis between water, land, and the natural processes which keep water clean and have been impeded by contemporary engineering. Outwater, an environmental engineer, describes her experiences with the Boston Harbor Clean-up project where she learned that industrial polluters are no longer the culprit in dirty water and where she began an investigation into the natural processes by which waterways cleaned themselves and how those processes can be restored in a new paradigm for water quality.
