Emergency Biohazard Cleanup Services in Aliquippa, PA

Aliquippa is a city in Beaver County, Pennsylvania, on the Ohio River about 18 miles northwest of Pittsburgh, formed by the merger of three towns: Aliquippa, Woodlawn, and New Sheffield.

The name Aliquippa was chosen by the Pittsburgh and Lake Erie Railroad in 1878 for its station, borrowed from Seneca Queen Alliquippa — though there is no evidence the queen herself was connected to this location.

Aliquippa is best known for the giant steel mill the Jones and Laughlin Steel Company began building along the Ohio River in 1905, which grew into one of the largest integrated steel mills in the world, stretching about seven miles along the river.

The mill's jobs sustained a population that peaked at 27,116 in 1930, when Aliquippa was one of America's quintessential company steel towns.

Aliquippa workers made labor history: firings of union organizers at the mill led to the landmark 1937 U.S. Supreme Court case NLRB v. Jones & Laughlin Steel Corp., which upheld the National Labor Relations Act.

The mill closed in 1984 during the collapse of the American steel industry and was demolished in 1988, setting off decades of population and economic loss.

Aliquippa had a population of 9,238 at the 2020 census — barely a third of its steel-era peak — living in about 4,250 households.

Aliquippa was formally chartered as a city in 1987, the same year it entered Pennsylvania's Act 47 program for financially distressed municipalities; it finally exited Act 47 on December 1, 2023.

The B.F. Jones Memorial Library, built in 1927 with money donated by steel tycoon Benjamin Franklin Jones's daughter, remains a historic landmark of the community.

Jones and Laughlin built Aliquippa as a planned company town of numbered hillside housing plans, each historically associated with a different immigrant nationality that came to work in the mill.
