Week 9

We would hope that it prohibits drilling altogether in two watersheds that supply millions of people with unfiltered drinking water, while imposing the strictest possible drilling standards elsewhere.

Interior Secretary Ken Salazar told a House subcommittee recently that a drilling technique known as hydraulic fracturing could be the “Achilles’ heel” that kills the natural gas industry.

A single well can cough up a million gallons of wastewater laced with carcinogens like benzene and radioactive elements like radium.

At the urging of Congress, the Environmental Protection Agency has begun an investigation of hydraulic fracturing’s effect on the environment.

The state’s Department of Environmental Conservation is nearing the end of a revised environmental impact statement that is due on June 1.

But he also fears, as we do, that public support for drilling will diminish unless the industry and its state and federal regulators do a better job of making sure the gas does no harm to drinking water.

Hydraulic fracturing involves blasting water, sand and chemicals into underground rock formations to unlock the gas they contain.

The oil and gas companies provided much of the underlying data, and there were few onsite inspections.

Ian Urbina’s recent series in The Times found that conventional wastewater treatment plants in Pennsylvania could not prevent radioactive contaminants from entering rivers that provide drinking water for millions of people.

The technique has become especially controversial in Pennsylvania, the epicenter of a big push for natural gas locked in the Marcellus Shale, a formation stretching from West Virginia to upstate New York.

The oil and gas companies provided much of the underlying data, and there were few onsite inspections.

An earlier E.P.A. study in 2004 was superficial and skewed toward industry.

It must also be thorough and transparent.

Ian Urbina’s recent series in The Times found that conventional wastewater treatment plants in Pennsylvania could not prevent radioactive contaminants from entering rivers that provide drinking water for millions of people.

But the risks have multiplied as the wells are drilled deeper and stretched vertically and horizontally to get at remote deposits.

At the urging of Congress, the Environmental Protection Agency has begun an investigation of hydraulic fracturing’s effect on the environment.

Like many others, Mr. Salazar sees natural gas, which America has in great abundance, as cleaner and more climate-friendly than coal or oil and a useful transition to alternative fuels.

The series also identified many instances of poor regulation.

The technique has been around for many years and has been used, mostly without incident, in hundreds of thousands of natural gas wells.

A single well can cough up a million gallons of wastewater laced with carcinogens like benzene and radioactive elements like radium.

Albany has been dithering for years over whether to allow increased hydraulic fracturing, and under what conditions and rules, in New York’s portion of the Marcellus Shale.
