A -- FRACTRUED CARBONATE ROCK GEOHYDROLOGY Sol. RFA-95-1. Due 042195. Contact Point, Stephen Kovash, (405) 436-8708. The USEPA, Robert S. Kerr Environmental Research Laboratory, in Ada, Oklahoma, is seeking assistance by cooperative agreement with non-profit organizations (minimum of 5% cost sharing required) or by interagency agreement with Federal Agencies qualified to conduct research in the geohydrology of fractured carbonate rock aquifers. The focus of the research should be to summarize, demonstrate, and extend the understanding of the capture zone concept for pumping wells as applied to fractured carbonate rock aquifers. It is anticipated that a balance between computer modeling/scientifc visualization and field observations will be demonstrated in a cost-effective charactrization at a dedicated field site. Project results will be expected to provide insights into the significance of preferred flow pathways and long-term storage zones within capture zones, with particular attention to aquifer remediation and protection. The project is anticipated as a three-year project with the total budget not to exceed $500,000 for the three-year period, pending availability of funds. Interested sources must request a solicitation package containing a scope of work, evaluation criteria, and additional instructions in writing before the response date of April 21, 1995. FAX reuests may be directed to (405) 436-8597. Telephone requests for the solicitation package or technical information will not be accepted. (079)
