Lagoon

The Bruin Lagoon Site covers approximately 6 acres (2.4 ha) in the borough. The site began operating during the 1930s as a disposal site for petroleum refining wastes. Until the 1970s, Bruin Lagoon was used for the disposal of wastes from mineral oil production, motor oil reclamation, crude storage tanks, and spent bauxite from mineral oil infiltration. The primary contaminants at the site were sulfuric acid, hydrogen sulfide, sulfur dioxide, and heavy metals.

In 1968, the lagoon overflowed, spilling approximately 3,000 gallons of acidic sludge into Bear Creek which borders the east side of the site. The spill killed more than three million fish in Bear Creek and the Allegheny and Ohio rivers.
