Hydraulic fracturing, or "fracking," is a dangerous drilling technique threatening water, air, wildlife and public health all over the United States. It's done by blasting millions of gallons of a chemical-water-sand mixture deep into the Earth to break up rock formations to harvest oil and gas.

In 2005, in a law known as the "Halliburton loophole," Congress exempted the chemicals used in fracking from regulation under the Safe Drinking Water Act --with one exception: diesel fuel. The Environmental Protection Agency has just asked for public comment on how it should regulate the use of diesel fuel in fracking.

Evidence is mounting throughout the country that fracking chemicals are making their way into aquifers and drinking water, and diesel contains the toxic substances benzene, toluene, ethylbenzene and xylene. Risking more chemical contamination of our drinking water is a no-go.

Take action to tell the EPA to take the immediate step of banning the use of diesel in fracking fluid.
