NOVA "The Water Crisis"

"The Water Crisis: Water, water everywhere...but just how useful is it? NOVA travels to the Adirondack Mountains where acid rain is killing many high elevation lakes; to the Mississippi River where chlorine has combined with natural and man-made organic chemicals to form cancer-causing toxic chemical substances; to California, where conservation recycling has had to become a way of life; and to Bedford, Massachusetts, where the town wells have been contaminated by industrial waste.

Original broadcast date: 11/25/80 Topic: environment/ecology"

The NOVA report mentions Dioxin, proven to be an aggressive cancer-causing agent in 1997, in the groundwater and town wells as a result of industrial waste from the BASF company on Crosby Rd in the late 1970's.
