What is an Injection Well?
Injection wells are often the last stop for fracking waste. These are the most dangerous kind of well to live nearby, as they can result in contaminated well water, contaminated aquifers, and even seismic activity.
The premise of injection wells that the fracking industry tries to sell the public on is that, once the wastewater is injected underground, it stays put - as if something swept under a rug will not have to be dealt with sooner or later. The issue is that underground systems are all hydrologically connected. Fluids migrate underground, and can make their way back to the surface.
Furthermore, injection wells are often made from old conventional wells, which were not designed to handle the kind of pressure an injection well must endure. Casing failures are common, and result in disastrous consequences for anyone nearby who relies on well water. They can even contaminate nearby gas production wells.
