Fracking starting to get some attention by US House democrats
From the Huffington Post
WASHINGTON -- Millions of gallons of potentially hazardous chemicals and known carcinogens were injected into wells by leading oil and gas service companies from 2005-2009, a report by three House Democrats said Saturday. The three Representatives are Henry Waxman of California, Edward Markey of Massachusetts and Diana DeGette of Colorado.
The report said 29 of the chemicals injected were known-or-suspected human carcinogens. The chemicals are injected during hydraulic fracturing, a process used in combination with horizontal drilling to allow access to natural gas reserves previously considered uneconomical.
The growing use of hydraulic fracturing has allowed natural gas production in the United States to reach levels not achieved since the early 1970s. However, the process requires large quantities of water and fluids, injected underground at high volumes and pressure. The composition of these fluids ranges from a simple mixture of water and sand to more complex mixtures with chemical additives.
The report said that from 2005-2009, the following states 100,000 gallons or more of fluids containing a regulated chemical under the Safe Drinking Water Act : Texas, New Mexico, Colorado, Oklahoma, Mississippi and North Dakota.
