Water, water everywhere... but just how useful is it? NOVA travels to the Adirondack Mountains where acid rain is hugging 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.
Seen in more than 100 countries, NOVA is the most watched science based television series in the world and the most watched documentary series on PBS. It is also one of television's most acclaimed series, having won many major television awards, most of them many times over.
