Site Background

The 120-acre Crystal City Airport site is located in Crystal City, Texas. From the 1950s to 1982, several aerial pesticide application businesses operated at the site. Site activities and waste disposal practices by the pesticide businesses contaminated soil with hazardous chemicals. Following cleanup, EPA took the site off the Superfund program’s National Priorities List (NPL) in 1995. Operation and maintenance activities are ongoing.

Several aerial pesticide applicating businesses that operated at the airport from early 1950s until 1982 left surface principal pollutants at the Crystal City Superfund site which include arsenic compounds (1,450 ppm) and pesticides, specifically DDT (2,400 ppm) and toxaphene (1,100 ppm).  Approximately 12,000 cubic yards of contaminated material wastes have been removed by verification monitoring that is now consolidated in the onsite vault.
