New faces will oversee the expanding gas drilling industry in Pennsylvania's Marcellus Shale.
As gas-drilling operations proliferated in Pennsylvania’s Marcellus Shale over the past couple of years, most of the hundreds of millions of gallons of briny wastewater they produced was eventually dumped into the state’s rivers. Much of the rest is unaccounted for.
The use of a mix of water and chemicals, known as hydraulic fracturing, or fracking, has generated controversy and a series of studies, orders and regulations in 2010 from the federal government and a number of states on the topic of gas drilling.

Testing has shown that methane gas in water wells across the country matches the methane being drilled for natural gas supplies. But a woman quoted in a New York Times report hinted that in Pennsylvania -- despite state official's conclusions to the contrary -- that may not be the case.
New rules in Wyoming require natural gas drilling companies to disclose the makeup of their hydraulic fracturing fluids, but two chemical manufacturers don't want to share their formulas with the public.
Memo from fired New York environmental chief says Paterson budget cuts would make it harder to clean up spills, respond to natural gas drilling in New York state.
New rules place Wyoming at the forefront of the national push to disclose chemicals used in <a href="http://www.propublica.org/special/hydraulic-fracturing-national">hydraulic fracturing</a>. Residents in drilling areas have complained about contamination of their wells that they believe is from fracking.
A state bulletin warns that environmental “extremists” may target public hearings and other events for criminal activity to protest natural gas drilling in rural parts of Pennsylvania, but drilling opponents say the threat is exaggerated.
