Biohazard Cleanup Near Rainbow White Oak, PA

White Oak is a borough in Allegheny County and a suburb of Pittsburgh, located about 15 miles southeast of downtown.

White Oak was named for a stand of white oak trees near the original town site.

White Oak was originally part of Versailles Township, one of the original townships of Allegheny County, and it was the site of Fort Reburn, a refuge where early settlers sheltered.

White Oak is a young borough by Pennsylvania standards: residents petitioned for incorporation on March 21, 1948, and the decree creating White Oak Borough was signed on June 24, 1948; its first borough building was inside the old Bowery School on Maple Street.

White Oak had a population of 7,630 at the 2020 census, down from 7,862 in 2010.

At the 2000 census, White Oak had 8,437 residents living in 3,678 households.

The borough spreads over 6.7 square miles and borders the city of McKeesport to the west, with a short stretch of its southern border crossing the Youghiogheny River.

White Oak is home to the 810-acre White Oak Park, one of the nine parks in Allegheny County's roughly 12,000-acre park system; opened in 1974, it is known for plant life found almost nowhere else in Pennsylvania, along with a dog park, wedding garden and miles of trails.

The land for White Oak Park was assembled through the Mellon family in 1958 and sold to the county, part of the same 3,600-acre acquisition that created six of the regional parks.
