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…
Air quality in the United States is governed by a complex regulatory structure that sets pollution limits and authorizes federal, state and local agencies to enforce them. The regulations which agencies enforce vary with the source of pollution, what they emit and the air quality in the region where they…
Creeping into the Fort Pitt Tunnel, angling for space at the Parkway East’s Grant Street exit, or elbowing into a gap in traffic on the Veterans Bridge, tens of thousands of people drive or ride into and out of Downtown nearly every day.
Bluer skies over southwestern Pennsylvania owe a debt to local, state and federal regulations that have evolved over decades to spur technological advancements and investment in controlling air pollutants from industrial plants to the cars we drive.
Air polllution’s place in the history of southwestern Pennsylvania is as prominent as the region’s mighty rivers and the steel industry that once crowded their banks. For nearly a century, it was a defining characteristic in the eyes of visitors, who pulled no punches when describing the grim conditions they…
Power companies aren’t alone in their shift away from coal. Steelmakers, industry groups and the federal government are spending millions looking for a way to make steel without coke, the carbon-rich form of coal used to fuel blast furnaces. Like coal-fired power generation, coke production is a major source of…
Shell Chemical Appalachia’s petrochemical complex has begun to rise from a dusty Beaver County brownfield that follows a slow bend in the Ohio River near Monaca. It took hefty tax incentives to secure it. The nation’s largest zinc smelter was razed to make room for it. More than 7 million…
Well pads, compressor stations, diesel truck traffic. Hydraulic fracturing, or fracking, involves many moving parts, some of which have the potential to vent pollutants into the air southwestern Pennsylvanians breathe.
At the Clairton Public Library in the industrial Monongahela River valley, patrons can check out “Moby Dick,” “To Kill a Mockingbird,” the adventures of Curious George and any number of Nancy Drew mysteries. They can read issues of Vogue and Popular Science. They can take home the music of Elton…
Despite the improvement in the region’s air quality in recent years, southwestern Pennsylvania still fails to meet federal health-based standards for various major air pollutants, such as ground-level ozone, sulfur dioxide and fine particulates, known as PM2.5. And that regional pollution elevates risks of cancer, respiratory ailments and other serious…
As their due date neared last fall, Ryan Poling and his wife faced a difficult decision. Did they want to raise their daughter in Pittsburgh, the city in which they’ve built a life during the last nine years, or pick up and move across the country, near Poling’s family in…
