The Toxic Chemicals Utilized
SkyTruth Fracking Chemical Database
SkyTruth maintains a database of chemicals that were reported by oil and gas drilling operators as being used in hydraulic fracturing operations. The database contains records for more than 27,000 frack operations from January 2011 through August 2012 in 24 US states.
Hydraulic Fracturing Process Chemicals
_By TOXMAP Admin on November 30, 2011 7:28 PM
Hydraulic fracturing (also called hydrofracking or fracking) is a process in which millions of gallons of water, sand and chemicals are pumped underground to break apart rock in order to release oil and natural gas. The US EPA Toxics Release Inventory (TRI) program requires facilities in certain industries that manufacture, process, or use significant amounts of toxic chemicals, to report annually on their releases of these chemicals. Hydraulic fracturing is currently not a TRI-covered industry and so is not represented in TOXMAP. EPA scientists are conducting a study of hydraulic fracturing to better understand any potential impacts on drinking water and groundwater.
Congress has released a report on hydraulic fracturing (PDF, 156 KB) that lists 29 toxic chemicals used in fracturing (see Table 3 of this report).
