You’ve probably answered this question many times, but many Aunt Ednas are still asking, “How do you ensure that drinking water is protected during fracking?”
We thought it might help to offer a new approach to how we answer questions about drinking water protection.

Before we begin a typical fracking process, we first build a well with three million pounds of cement and steel barriers. These barriers are designed to protect drinking water, which is generally less than a thousand feet below the surface. The layers of cement and steel ensure that everything that’s supposed to stay in, stays in and that everything that’s supposed to stay out, stays out.
Because we are fracking more than a mile below the surface, there are thousands of feet of rock between the fracture zone and the drinking water aquifers. These rocks weigh millions of tons and create a natural layer of armor, in addition to the man-made barriers.
