New Report Questions PA Environmental Chief’s Assertion About Methane Contamination

Leroy Township, PA Gas Migration Continues

In the Leroy Township area an actual gas well ‘blowout’ event is ongoing, but the drilling company and the PA DEP insist that the ‘event’ is over.  Gas Safety’s testing has shown that the event is continuing. An initial day of testing was done … Continue reading

Utah Finds High Wintertime Ozone Pollution Near Oil, Gas Wells

Like Wyoming, Utah Finds High Wintertime Ozone Pollution Near Oil, Gas Wells
By Mark Jaffe, The Denver Post, February 26, 2012

High levels of winter ozone air pollution have been recorded in a Utah oil and gas field — after the phenomenon was seen in Wyoming — raising concerns that … Continue reading



After a Marcellus gas well is drilled and hydraulically fractured, open flaring is often used to test production of the well. The EPA and Pennsylvania DEP enforce limited air quality regulations around Marcellus Shale natural gas wells and facilities (Most gas sites are permitted individually instead of cumulatively).

A … Continue reading
