Government Information: Hydraulic Fracturing


The immense growth in Oklahoma and our nation of enhanced natural gas and oil recovery via the process popularly known as “fracking,” and more precisely known as “Hydraulic Fracturing,” has created an economic boom. “Shale oil” and “Shale gas” is trapped within shale formations; injecting combinations of water, sand, and chemicals at high pressure causes the shale to crack which then releases the gas or oil. But mismanaged fracking can also release hazardous chemicals into drinking water and air, and also cause small earthquakes. Here are some links to information about fracking in general and its potential adverse health effects.
