Chemical Analysis of Fracking Fluid
Halliburton Company, an entity actively performing hydraulic fracturing in Colorado, has made public a "fluids disclosure" in regards to the hydraulic fracturing fluid that they use. Below is the complete list of hydraulic fracturing fluids introduced into Halliburton well sites, specifically sites in Colorado, our focus area.

*In certain cases, a small percentage of constituents may be protected under existing agreements with suppliers and customers. In these situations, CAS numbers are not listed – but the constituent's listing as hazardous on the MSDS is, as well as other common uses when identified.
**The CAS Number of a compound is a useful way to identify a chemical over its name. For example, the compound CAS 64-17-5 refers to ethanol. Ethanol is also known as ethyl alcohol, ethyl hydrate, absolute alcohol, grain alcohol, hydroxyethane. The CAS number is the same for all these names. Therefore, by using the CAS number you can avoid the issue of multiple names for the same chemical.
