Natural Gas Drilling, Hydrofracturing, and Ground Water – Drink Up?

A couple of YouTube videos have been making the rounds and causing some alarm among the ever-increasing number of homeowners who have active natural gas drilling in their area, and rely on groundwater for their drinking water supply. This video shows common, normal operations at a modern natural-gas drilling site in western Colorado, operated by the Canadian company EnCana, a major player in the Rockies. One video shows drilling fluids being stored onsite in a plastic-lined open pit (a “fluid reserve pit”) while the well is hydrofractured, or “fracced.” The other video shows this same pit being closed: as a crew removes residual fluids and pulls out the liner, a bulldozer buries the pit.


We’ve created a small gallery showing the drill site depicted in these videos, and adjacent residences. Although the operations depicted are probably allowed by Colorado law, nearby homeowners who have water wells for drinking and bathing are concerned about these practices as drilling permeates the area. Multiply this scene tens of thousands of times, and you get the idea what’s been happening in recent years with drilling in many parts of the country.

UPDATE 9/16/09: In response to a comment, we thought folks might appreciate these links to other resources about fracking:

  • A summary report on chemicals found in fraccing fluids, their toxicity, and health effects
  • Tables that list chemicals used in drilling and fraccing
  • This press release from The Wilderness Society supporting pending legislation that would require companies to publicly disclose the chemicals used in fraccing
  • Announcement that EPA found fraccing chemicals contaminating residential water wells in Pavillion, Wyoming
  • A wealth of additional information on hydrofracturing from Earthworks

Roan Plateau – EWG Report

Environmental Working Group just released a compelling report that shows the history of gas and oil drilling on and around the Roan Plateau in western Colorado. This work puts the numbers behind the tremendous burst of drilling illustrated by SkyTruth images.
