A University of Michigan survey finds that fracking is limited in Michigan with an estimated 6 percent of the state's local jurisdictions reporting existing fracking operations or some kind of activity to expand them, but the topic generates significantly more debate.

When it comes to factors supporting fracking in Michigan communities, 43 percent of responding local officials said revenue for land-owners was a primary driver.

Factors discouraging support for local fracking are reported to be more common, with 57 percent of officials polled citing environmental concerns such as potential risks to water resources or other environmental damage.

According to the study by the U-M Ford School's Center for Local, State, and Urban Policy, 35 percent of government officials who have heard of fracking say its an active topic of discussion within their communities. Sixty-one percent said fracking is "not an issue at all."

Where fracking is an active topic, local officials believe that their citizens are more likely to oppose (37 percent) than support (11 percent) fracking in their communities.

Fracking is the common term for hydraulic fracturing, a process which releases natural gas by injecting a mixture of water, sand and chemicals at high pressure deep into the ground through encased wells to create and expand fractures in the rock.
