What is the historical context of our “H₂Oh! Why Our Rivers Matter” exhibit?

It’s no coincidence that Pittsburgh was born from the strategic freshwater confluence where the Monongahela (or “the Mon,” as Pittsburghers call it) and Allegheny Rivers form the Ohio River. The city became historically relevant because it joined the east with the midwest through mineral-rich areas of deposits. By harnessing these rivers, Pittsburgh rapidly rose to international prominence, first as the “Glass City,” then the “Iron City,” and then the “Steel City.” The production of steel was wrought with environmental consequence. For decades, the rivers were used for waste disposal. Coupled with smog from industrial pollution, Pittsburgh was not exactly an environmentalist’s dream city.

Today, we are proud of Pittsburgh’s environmental renaissance. Sewage treatment (beginning in 1959), pollution ordinances, and a shift in industry from manufacturing to service and technology all helped to drastically improve river conditions in Southwestern Pennsylvania. Iconic Pittsburgh cityscapes often feature the three rivers and numerous bridges. In 2009, Pittsburgh hosted the G20 summit, and it is routinely recognized as a most “livable city.” By harnessing new technologies, scientists have helped to improve and monitor the quality of our rivers, which have hosted some of the world’s top professional fishing tournaments and are recognized by National Geographic as a kayaking destination!
