High-tech steam lays the green clean on Visalia Superfund site

A new underground steam cleaning method has cleaned up a creosote soaked Superfund site 100 years ahead of schedule and restored the water to being drinkable.

Compared to the 10 pounds per week of the conventional pump-and-treat process, the new operation achieved nearly 46,000 pounds per week over the first six weeks – a rate of over 5,000 times faster than previously.
