The area was originally inhabited by Native American tribes, but soon overtaken by Europeans.

Springdale originally got its name in the year 1820 by either Hannah Keene or her daughter, Frances.

Among these settlers were familiar names such as Pillow, Coe, Remaley, Henderson, Mellon, Brackenridge, Denny, Hanna, Keene, Shoop, and Moyer.

The Riddle Run joins the Allegheny River at Springdale.

34.4% of all households were made up of individuals, and 16.5% had someone living alone who was 65 years of age or older.

The Springdale Free Public Library serves the borough.

Springdale is also notable for its proximity to a variety of industrial locations, including a local PPG plant (which celebrated its 75th anniversary in June 2022[14]), and the formerly active Cheswick Generating Station, a coal-fired electric power plant known for its two large smokestacks which dominated the skyline for miles until their demolition in June 2023.
