Removal of Arsenic from OU Water Paul Gerber, Collin Martin, John Siska Executive Summary Our group has been exploring different treatment options (including water purchase) to remedy the University of Oklahoma’s arsenic groundwater problem. Currently, the average level of arsenic in OU’s potable water supply is 32 ppb, while the federal limit for arsenic in potable water is 50 ppb. In January 2006, this limit will drop to 10 ppb, forcing OU to address the high level of arsenic in its water. Our group has examined background information on sources of arsenic in OU’s water, compliance options, initial design analyses, and cost estimates for several different treatment processes and configurations. For water treatment, our team studied Ion Exchange, Reverse Osmosis, Microfiltration, Nanofiltration, and Ultrafiltration. The most economically viable treatment option was found to be ion exchange. We have found that the proper course of action and the costs for these courses of action
