Last week, we reported on evidence that hydraulic fracturing, a form of natural gas drilling used by Halliburton and other contractors in a number of states, has led to water pollution. One of those states was Wyoming, and in August, we visited the wide-open spaces of Sublette County to see the drilling fields there. You can see the audio slideshow here:

Another one of those states is Colorado, and a version of the story also ran this morning on the Denver Post’s front page.
