Naturally Occurring Radioactive Materials (NORM) is a common and costly contaminant of produced waters associated with natural gas production and exploration. One way of combating this problem is by identifying the problem beforehand. Our approach to this problem involves development of NORM prediction capabilities based on the geological environment. During quarter seventeen of this project, work has continued under the project's approved revisions. We have received the first of our produced water samples and the samples have been analyzed for NORM activity. Additional tests are also being performed. We are also attempting to acquire samples from additional sites.
