The Region’s Top 10 Air Polluters

Although the region’s air has improved dramatically from the height of Pittsburgh’s industrial past, southwestern Pennsylvania remains home to factories and power plants that release millions of pounds of toxic chemicals into the air. The U.S. Environmental Protection Agency uses Toxic Release Inventory (TRI) data to track toxic chemicals released…

Inconspicuous and Dangerous

The heavy smoke is gone. But particulates 30 times smaller than the diameter of a human hair and gases formed by the reaction of sunlight and fossil fuels exhaust remain as the region’s most widespread, stubborn and dangerous air quality problems.

Up in the Air

Southwestern Pennsylvania and air qulity have long had a complicated relationship. For the better part of a century, the region had been a place so polluted from the soot of industry and homes heated by coal that street lamps were lit in the afternoon and walking a single block could…

Neither, Either, Or

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.…

Clouds gathering over Pittsburgh

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…

Nature’s Comeback

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…

Sudden goodbye

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.

Is better good enough?

A standing-​room-​only audience has packed the Avalon Municipal Building on a rain-​soaked April evening to hear Allegheny County Health Department officials explain the latest consent decree to correct air quality violations at the coke works across the river. It’s a tough crowd.

What we say (and do) about the environment

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…

Warning Signs

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.

Greening the region

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…

A World Leader

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…

Was Rachel Carson Right?

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…

High-​Tech Sylvania

On a cool morning late in 2006, the phone rang in Esther Barazzone’s office, a suite overlooking Chatham University’s cozy Shadyside campus. Preoccupied by the re-​accreditation of the undergraduate women’s program and preparations for new graduate degrees, the president was unprepared for the question she heard on the line from Dan…

Facing Extinction

Wildlife biologists Greg Turner and DeeAnn Reeder slip into the sort of coveralls you would expect to see on an infectious disease ward and enter the cold, musty confines of an old Fayette County mine.
