Evaluation of Subsurface Flow and Free-water Surface Wetlands Treating NPR-3 Produced Water - Year No. 1

This paper is a summary of some of the activities conducted during the first year of a three-year cooperative research and development agreement (CRADA) between the Department of Energy (DOE) Rocky Mountain Oilfield Testing Center (RMOTC) and Texaco relating to the treatment of produced water by constructed wetlands. The first year of the CRADA is for design, construction and acclimation of the wetland pilot units. The second and third years of the CRADA are for tracking performance of pilot wetlands as the plant and microbial communities mature. A treatment wetland is a proven technology for the secondary and tertiary treatment of produced water, storm water and other wastewaters. Treatment wetlands are typically classified as either free-water surface (FWS) or subsurface flow (SSF). Both FWS and SSF wetlands work well when properly designed and operated. This paper presents a collection of kinetic data gathered from pilot units fed a slipstream of Wyoming (NPR-3) produced water. The pilot units are set up outdoors to test climatic influences on treatment. Monitoring parameters include evapotranspiration, plant growth, temperature, and NPDES discharge limits. The pilot wetlands (FWS and SSF) consist of a series of 100-gal plastic tubs filled with local soils, gravel, sharp sand and …

Latin America: Terrorism Issues and Implications for U.S. Policy (open access)

Latin America: Terrorism Issues and Implications for U.S. Policy

Latin American nations strongly condemned the September 11, 2001 attacks on NewYork and Washington and took action through the Organization of American States and the Rio Treaty to strengthen hemispheric cooperation against terrorism and express solidarity with the United States. Many nations are taking actions to investigate possible regional linkages with the Osama bin Laden terrorist network, and to ensure that their financial sectors are not being used by terrorists. In the aftermath of the attacks, the U.S. policy toward the region will likely include a re-invigorated security agenda, with the development of new cooperative mechanisms against terrorism. The terrorist attacks will have implications in several areas, including the extent of hemispheric cooperation against terrorism, anti-money laundering efforts, Andean counter-narcotics strategy, the trade agenda, regional economic stability, and policy toward Mexico and Cuba.
