Abstract |
The Westline site, located in the town of Westline, McKean County, Pennsylvania, is a 40-acre tract of land formerly used as a lumber processing facility. Between 1901 and 1952, the onsite chemical plant converted lumber into charcoal, methanol, and acetic acid. In 1952, the plant was closed due to equipment deterioration and declining profits. Waste tars containing high levels of polynuclear aromatic hydrocarbons (PAHs) and various phenolic compounds were left onsite. An Emergency Removal Action was implemented in 1983 to remove the largest tar deposit, and a Record of Decision was signed in July, 1986, to address the excavation and offsite incineration of remaining tar deposits and contaminated soil. The second operable unit addresses potential ground water contamination. In 1985 high levels of benzene were found in two onsite monitoring wells. Additional tests indicated the presence of toluene, trichloroethane, phenol, and other VOCs; however, benzene was the only contaminant that exceeded Federal Maximum Contaminant Levels (MCLs) of 5 microgram/l, and is, therefore, the primary contaminant of concern. The article describes the condition of pollution at the site, EPA's determination and adopted actions. |
