When U.S. Environmental Protection Agency Acting Administrator Andrew Wheeler visited Pittsburgh on October 24 last year, his first order of business was to visit a Range Resources well-pad outside Washington, Pa., announcing that the EPA would continue “removing regulatory barriers and leveling the playing field for American companies.”
Watershed expert April Claus called to the 20 Quaker Valley High students splashing through a creek bed in their muck boots: “Who wants to release the brown trout?” They were part of Claus’s environmental science internship — the Quaker Valley Creekers. And on that autumn day they waded into Little Sewickley Creek,…
What are the so-called “waters of the United States” and why did the Obama administration expand the definition? To understand that is to understand the evolution of environmental regulation in the United States and how the nation’s courts have interpreted what’s protected.
Determining where water begins and ends seems a matter of physical properties, of whether two hydrogen molecules are bonded to oxygen, and how much of it exists. Where is it located, and will people eventually drink it? Swim in it? Fish in it? This molecule, essential to life, has become…
If you want to explore the vexing subject of global climate change, Seamus McGraw is the guy to have as a tour guide. He will not torture your brain with elaborate science, tax your patience with lectures about evil consumer habits, or bash you over the head with partisan arguments.…
As his rowboat swept over Penn Avenue, Charles H. Allard looked for the bronze tablet on the Horne’s building. The object commemorated the high water mark of the Flood of 1907, previously the most severe flood to ravage Pittsburgh. Allard, reporting for the Pittsburgh Post-Gazette on March 18, 1936, couldn’t…
Every year, while spring was busy prying away the season from winter’s grasp, my family would make the trek down to Deep Creek, Maryland, to visit my grandparents’ cottage. The drive from our Long Island home was just over seven hours, which, to a kid with very little concept of…
In 1967, we arrived at our island cottage in Michigan’s Upper Peninsula, and of course, the first thing we kids did was explore our distantly familiar summer home. On that particular day, we found a bat inert on the dining room floor.
Lori Rieger and Kim Haynes are strolling Point State Park on a July afternoon that is sunny, hot and humid enough to notice. It’s the kind of day that invites ozone pollution to accumulate at levels that violate federal air quality standards, which is something Pittsburgh and the region do…
On the first warm day of May, Jim Chestney cuts through thickets of black huckleberry and laurel and ponders his impending climb to a timber rattlesnake den on a central Pennsylvania mountain.
It was 1868 — when looking down from the Hill District to smokestacks belching fire and smoke, a riverbank littered with coal barges and railroads, and a bottomland saturated with muddy streets and gritty row houses pressed hard against the Allegheny River, Boston writer James Parton described Pittsburgh as “Hell with the…
Sitting in the bright, airy café at Phipps Conservatory and Botanical Gardens, Richard Piacentini stamps his foot on the floor. The tiles he thuds against are simple white squares. However, that hardly noticed floor has proven to be both bane and catalyst to a sea change in thinking about every…
Patricia DeMarco, Director of the Rachel Carson Institute at Chatham University, has heard the question before. Has history — and science — proven that Springdale, Pa., native Rachel Carson was right in her book, “Silent Spring”? Not just about the most celebrated of her attacks — the impact on the environment of the widely used herbicide…
