Gas Drilling's Environmental Impact

Michigan

How to read these graphs:

The graphs on the left show the rate of growth compared to the earliest year for which we have data -- in most cases 2003. The gray lines represent a theoretical constant annual rate of change.

The bar charts on the right show the actual values for each year we have data. For example, in 2008, Michigan had 576 new wells drilled.

State Data

The number of new wells drilled in Michigan for 2009 do not reflect the entire year.
