An
eye-popping report published in the Denver Post on Monday is a cause for
serious concern regarding community water supplies around the country.
A
common and relatively new process called hydraulic fracturing, pioneered by
Halliburton, and developed as a method of releasing natural gas, originally was
considered safe by a 2004 EPA study, which found no risk posed to drinking
water.
This
investigative report, researched and written by the new nonprofit journalism
organization ProPublica, details how it was discovered earlier this year that
the process actually poses a very serious risk to public drinking water, due to
the massive amounts of toxins released. From the Post:
The process has been
considered safe since a 2004 study by the Environmental Protection Agency found
that it posed no risk to drinking water. After that study, Congress even
exempted hydraulic fracturing from the Safe Drinking Water Act. Today,
fracturing is used in nine of every 10 natural-gas wells in the United States
So
the use of this technology is widespread. And just how bad is it?
An investigation by
ProPublica found that water contamination in drilling areas around the country
is far more prevalent than the EPA asserts.
This investigation also
found that the 2004 EPA study was not as conclusive as it claimed to be. A
close review shows that the body of the study contains damaging information
that wasn't mentioned in the conclusion. In fact, the study foreshadowed many
of the problems now being reported across the country.
How
could this happen? Granted, the Bush administration has used the EPA as an
industry tool as much as possible since 2001. But this means the scientists knew
this was a problem, but the agency went ahead anyway. Seems like if stronger
whistleblower protections for federal scientists were in place, maybe more
people would have spoken out about the problem.
But
that’s not the worst part – the EPA scientists don’t know exactly what the
problem is now, because they don’t know exactly what chemicals are used in the
process. Check it out:
It is difficult to pinpoint
the exact cause of each contamination or measure its spread accurately because
the precise nature and concentrations of the chemicals used by industry are
considered trade secrets. Not even the EPA knows exactly what's in the drilling
fluids. And that, EPA scientists say, makes it impossible to vouch for the
safety of the drilling process or precisely track its effects.
Meanwhile,
this process has allowed for a surge in natural gas drillings across the
country. And that continues to this day.
