[ Hydraulic fracturing](https://earthworks.org/issues/hydraulic-fracturing-101/?gad_source=1&gad_campaignid=23149209067&gbraid=0AAAAADlFpDEnljPk5OLnOKs66rJC1jZPV&gclid=CjwKCAjw6rfSBhAqEiwA_yocpuIRasC9vilmF-TIE9FMct54QZsodzp2lJnGtqq1BriBvml0w36KgBoC2ZUQAvD_BwE), also known as fracking or fracturing, is the process of making small cracks or fractures in underground rocks to release the oil or natural gas inside. Scientists must analyze the physical characteristics of the rocks to be fractured before fracking can begin.

## The Fracking Process

Narrow shafts, or boreholes, are drilled into the rocks and cased with steel pipes. A pressurized mixture of water, sand and chemicals, known as fracking fluid, is then injected into the rocks. The fluid cracks the rocks and fills the cracks with sand, allowing natural gas or oil to flow up the boreholes. Following fracking, [wastewater](https://blog.polyprocessing.com/blog/effective-wastewater-treatment-chemical-storage), known as flowback, returns to the surface for collection. It is then stored in tanks or pits for treatment or disposal. On-site storage and [treatment](https://blog.polyprocessing.com/blog/storage-challenges-of-wastewater-treatment-chemicals) facilities eliminate the need to truck flowback off-site.

## Mitigating Fracking Risks

Fracking fluid typically contains between three and 12 chemicals, depending in part on the characteristics of the rocks being fractured. Commonly used chemicals include [hydrochloric acid](http://www.polyprocessing.com/chemical-storage/hydrochloric-acid/), calcium chloride, sodium chloride, [sodium hydroxide](http://www.polyprocessing.com/chemical-storage/sodium-hydroxide/) and citric acid. These chemicals serve various purposes, from controlling bacteria to decreasing corrosion of the steel casing. [Hydraulic fracking](https://earthworks.org/issues/hydraulic-fracturing-101/?gad_source=1&gad_campaignid=23149209067&gbraid=0AAAAADlFpDEnljPk5OLnOKs66rJC1jZPV&gclid=CjwKCAjw6rfSBhAqEiwA_yocpuIRasC9vilmF-TIE9FMct54QZsodzp2lJnGtqq1BriBvml0w36KgBoC2ZUQAvD_BwE) poses a risk of surface and groundwater contamination through chemical leaks and spills onto the ground or into nearby rivers and streams. This risk can be minimized through proper chemical storage.

## Smarter Chemical Storage Solutions

![hydraulic_fracture.png](https://blog.polyprocessing.com/hs-fs/hubfs/hydraulic_fracture.png?width=200&name=hydraulic_fracture.png "hydraulic_fracture.png")As a leader in cross-linked polyethylene chemical tanks, Poly Processing provides safe and reliable solutions for on-site chemical storage. Our extensive product range includes:

### Vertical Tanks with Integrally Molded Flanged Outlet

Our vertical tanks with [Integrally Molded Flanged Outlet (IMFO®)](http://www.polyprocessing.com/innovations/imfo/) help minimize the risks associated with traditional vertical tank maintenance. They also offer superior long-term structural integrity and net positive suction compared to tanks with post-production inserts.

### SAFE-Tank® System

It eliminates the need for expensive, high-maintenance secondary concrete containment areas.

### PolyGard™ Steel Vessel Lining

Popular with national rental companies, it molds to the inside of a tank, acting as a barrier between the steel and the substance being stored.

With manufacturing facilities in Louisiana, California and Virginia, we can ship your order from the facility closest to you, saving both time and money.
