The searchable FracFocus site is managed by the Ground Water Protection Council and the Interstate Oil and Gas Compact Commission, two intergovernmental agencies. The U.S. Department of Energy provided financial assistance.

FracFocus — — is the only site that offers the public a look at how much water drillers in Ohio are using. It went online in April 2011 and covers well drilled after Jan. 1, 2011.

It is voluntary in Ohio but mandatory in some other states.

Companies provide the site with information, including:

• Well location by longitude and latitude.

• Vertical well depth.

• Date the rock underground was fractured.

• Volume of water used in the fracking process.

• A list of chemicals used, their purpose, the chemical’s ingredients, the maximum ingredient concentration (a percentage by mass) and the active ingredient concentration in the fracking liquid (again a percentage by mass).

Companies are allowed to keep some materials undisclosed as proprietary or trade secrets. Information comes from the chemical suppliers for the drilling, and there is no third-party verification.
