Chemicals associated with CSG - Hydraulic Fracturing (Fracking) operations
This is a long List. The most nasty substances are at the start. It is important to note that these substances have not been randomly found on numerous sites on the internet. This list is compiled from government websites and peer reviewed literature like, the EPA in the US, APPEA - the Australian Petroleum Production & Exploration Association, Fracfocus - an organisation that houses voluntary disclosure reports submitted by oil and gas drilling operators about the chemicals they used in hydraulic fracturing operations across the United States and the US HOUSE OF REPRESENTATIVES - COMMITTEE ON ENERGY AND COMMERCE. And there are more classed as "Trade Secrets" or Proprietary or just undeclared. See our References section for full details.
