Back when Boston Harbor was a cesspool

This 1969 video by Derek Lamb and Lawrence Rosenblum of MIT brings us back to the time when raw sewage flowed into Boston Harbor and Spectacle Island glinted in the sunlight from the thousands of pounds of shattered glass littering the ground around the abandoned horse-rendering plant - and the Long Island Bridge still stood. Watch video.

A nearly 10-mile-long, deep, rock tunnel channels cleaned water from the Deer Island Treatment Plant into Massachusetts Bay. It was a miraculous feat of engineering except for one thing: there was no plan in place to finish the job. And this had deadly consequences.
