A recent federal study found chemicals used in hydraulic fracturing, better known as fracking, are potentially hazardous.?This is good, though not unexpected, news.
The in-depth review was conducted by the U.S. Department of Energy. Fracking is among methods used to free natural gas deposits from deep within the earth.
Although not new by any means, the method has come under fire from some quarters in recent years because of the perceived threat to groundwater acquifers.
But here's the thing: Fracking is occuring well below where acquifers are located, typically many thousands of feet below. It isn't reasonable to believe that chemicals will migrate up, denying the laws of gravity.
The recently completed DOE study, we trust, will put those fears to rest.
That said, federal regulators must still be vigilant in monitoring the folks that drill natural gas wells.
As has been pointed out on numerous occasions, the casings that line the wells must be well maintained for failure there could still cause pollution.
In the meantime, U.S. consumers can continue to enjoy the relatively low prices of natural gas, with the added benefit that we don't have to fight wars and spend lives to secure a long-term supply.
