Hydrofracturing, also known as hydrofracking, hyrdofracting, or 'fracking,' is a method used by groundwater professionals to develop and rehabilitate wells that are not providing enough water. The Hydrofracture procedure involves lowering a borehole packer into a water well, expanding it below the casing/static level and above the fracture system. This isolates the production zone from the rest of the well. Water is then pumped down through the water injection pipe at high pressure and high volume. The pressure and flow created in the production zone cause small, tight fractures in the rock to open up and spread. The newly opened and flushed out fractures provide connections between nearby water-bearing fractures and the borehole, ultimately increasing the yield of the underperforming well.

Sediment presence in a well can seal existing fractures in a well over time, diminishing the water flow of a well. In the Northeast, there is a widespread presence of iron and manganese. Over time, these minerals can build up and clog the arteries that feed a well. Hydrofracturing can clean out these fissures and restore the flow of once productive fractures.

There are two kinds of fracking, the single frack, which uses a single packer to provide a general fracturing of water-producing fissures, and the zone frack, which uses a straddle packer to isolate specific areas to fracture.
