Polluting surface water or underground aquifers is
about as likely as "shooting a bottle rocket to the moon," claimed Richard
Ward, the moderator at a hydraulic fracturing forum sponsored by the Bureau of
Land Management (BLM). Ward, who is also the director
of energy initiatives at the Aspen Science Center, added that "well
integrity is absolutely key" in his address to 200 farmers and environmentalists in Bismarck, North Dakota.
Hydraulic fracturing or "fracking" is an underground
method that uses pressurized fluid and sand to fracture rock and recover oil
and gas from depths up to two miles. In North Dakota, hydraulic fracturing is
credited with opening up the Bakken shale and Three Forks formations. Elsewhere,
fracking has been blamed for endangering water quality and poisoning wells.
In the American West, the BLM manages 250 acres of
federal land and has leased nearly 40 million acres to oil and gas drillers.
According to Theresa Hanley, the BLM's assistant director for Montana and the
Dakotas, 90% of this drilling involves hydraulic fracturing, a process whose
chemicals many companies refuse to reveal.
Although Richard Ward was quick to dismiss the
chances of contamination, some participants at the BLM's Bismarck conference remained
skeptical. Don Nelson, the spokesperson for an environmental group called the
Dakota Resource Council, called for companies to disclose the ingredients used
in fracking operations. Federal law still exempts drillers from having to do
so.
Is the BLM shooting straight in the Dakotas when it
dismisses risks to ranchers as like "shooting a bottle rocket to the moon"?
