Sullivan Awarded Oronogo Remedial Work
The U.S. Environmental Protection Agency Region VII has awarded Sullivan International Group a $22 Million dollar remedial project at the Oronogo-Duenweg (Oronogo) Mining Belt Site in Jasper County, Missouri. Sullivan has been contracted to begin the remediation work which will focus on the removal and disposal of mining wastes and surface soils contaminated with heavy metals, both of which constitute a significant source of potential exposure to people and the environment. The primary contaminants of concern are lead, cadmium and zinc.

The Oronogo Site was one of the most productive lead and zinc ore sites in the world. Mining and smelting activities began in the Tri-State area of Oklahoma, Kansas and Missouri around 1830 with the most productive years being from the early 1900’s to about 1950 and continued to operate through the 1970’s. During this time, approximately 160 million short tons of the ore production was derived from Jasper County. Today, approximately 10 million tons of wastes remain on the Site over 7,000 acres.
