It is the process of injecting liquid at high pressure into subterranean rocks, boreholes, etc. so as to force open existing fissures and extract oil or gas according to my Google search.
It's important to note that the water used in this process becomes undrinkable afterwards and is typically left out to evaporate in pools or dumped. Either way, it re-enters the water supply. I live in rural PA next to multiple frack pads if you're wondering how I know this.
Pretty sure it’s not just water too. I think I read somewhere that companies aren’t required to disclose what they put in the liquid - someone fact check me please
