To draw out difficult-to-access reserves of gas, crews drill thousands of feet into the earth and pump in highly pressurized, chemical-laden fracking fluids. This allows them to get the gas out — but the process leaves a mess in its wake.
Fracking wastewater contains acetaldehyde, ammonium chloride, arsenic, benzene, formaldehyde, lead, mercury, radium and hundreds of other chemicals. The controversial practice pollutes water supplies and land with these toxins — which are so substantial that, in the most affected areas, household tap water can sometimes be set afire as if the water were gasoline. (Check out the 2010 documentary film Gasland for footage of this.)
