These former industrial waste injection wells in Ranger, Eastland County are currently in the Operation and Maintenance phase of the Superfund Program.

Site Background

The Sonics International, Inc. site (the site) is located north of Farm Road 101, approximately two miles west of Ranger. Two permitted industrial waste injection wells on this site were used for subsurface disposal of varying organic and inorganic hazardous wastes. Surface soil became contaminated because of surface equipment leaks and blowouts of one of the injection wells during well workovers. Records document that the majority of wastes injected were acid solutions and chlorinated solvents.
