Watch Surface & Subsurface Waters

Gripping and enlightening, this program shows the interconnection of surface and subsurface waters. Two expert scientists enter a Florida spring, crystal-clear waters floating over a heart-stopping tunnel drop into the black depths, and then follow an underground river for several miles. The water turns turbid, revealing amazing amounts of debris: tires, oil barrels, and other trash. At the same time, another team humorously tracks them from above, through houses, golf courses, and busy traffic, revealing how humans unsuspectingly pollute the very water they drink, and explaining how to avoid doing so.
