Biohazard Cleanup Near Borough Beaver, PA

Beaver is a borough and the county seat of Beaver County, Pennsylvania, sitting near the confluence of the Beaver and Ohio rivers about 30 miles northwest of Pittsburgh.

Beaver stands on the site of Fort McIntosh, a Revolutionary War-era frontier fort; after the war the fort housed the First American Regiment, the oldest active unit in the United States Army, before it was abandoned in 1788.

Beaver was laid out in 1792 under a 1791 act of the state legislature, became the county seat of newly formed Beaver County in 1800, held its first county court in 1804, and was incorporated as a borough in 1802.

Beaver grew steadily until the Pittsburgh and Lake Erie Railroad arrived in 1879 and sparked a major growth spurt; a massive flood in February 1884 caused extensive damage in the borough.

Beaver's population peaked at 6,360 in 1950 and was 4,438 at the 2020 census, living in 2,132 households.

In 1996, almost the entire borough of Beaver was listed on the National Register of Historic Places as the Beaver Historic District, centered on Third Street and including the Matthew S. Quay House, a National Historic Landmark, and the Fort McIntosh site.

Beaver's mayor Robert Linn served for 58 years, from 1946 to 2004, making him one of the longest-serving mayors in United States history.

Beaver has been a designated Tree City USA community since 1997.

Beaver's children are served by the Beaver Area School District, whose Beaver Area High School is located in the borough.

The Beaver Area Memorial Library, which began as a small book collection in the basement of the Beaver Trust Co. in the 1940s, was dedicated in its own building on April 8, 1962.
