TOXMAP: Learn about toxic chemicals used in hydraulic fracturing & Update [Wyoming water wells very likely contaminated by fracking]
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).

Editor’s note: Synthetic musk is one of the pollutants of emerging concern to be discussed Oct. 11-14 in Detroit at the 2011 Great Lakes Week. Detroit Public Television is providing ongoing coverage of Great Lakes Week at greatlakesnow.org
Some scientists worry that the chemicals that make lotion, soap, trash bags and a myriad of household products smell good are an emerging class of pollutants that threaten environmental and human health.
There is “supporting evidence that more study and research need to be done,” said Antonette Arvai, a physical scientist with the International Joint Commission, a U.S. and Canadian agency that will discuss newly emerging pollutants at its biennial meeting in Detroit this week.
Use of fragrant chemicals in the United States has doubled since 1990. Arecent study by the commission identifies synthetic musk fragrance, used in a great number of personal care and cleaning products, as a chemical of emerging concern.
“When musk is applied to the structure of a cell wall, more toxins can pass through it,” Arvai said. The commission has recommended that scientists and regulatory authorities in both countries study the health risk of synthetic musks.
Concerns go beyond human health. Synthetic musk accumulates in aquatic organisms over time. A2009 studyinEnvironmental Toxicology and Chemistryreported that two musk fragrances, Galaxolide and Tonalide, were found in every sample of fish taken from the North Shore Channel in Chicago.
A large portion of world-wide musk production is Galaxolide and Tonalide.
