Title: Microbial Treatment of Naturally Occurring Radioactive Material (NORM)
Investigators: Lee R. Krumholz
Institutions: University of Oklahoma
EPA Project Officer: Bala Krishnan
Project Period: July 1, 1999 to June 30, 2000
Project Amount: $9,977
Research Category: NORM remediation
Objective: The project objectives are to determine the feasibility of using a sulfate reducing microbial consortium from subsurface sediment for the dissolution of NORM containing pipe scale.
Following incubations, remaining solid phases were extracted with 1 N HCl. Radioactivity in the culture supernatant and the acid soluble material were determined and plotted (Fig. 4). These latter data show that radio activity has been released into solution following sulfate reduction activity.
