Calibrated BASINS modeling is used to demonstrate compliance with bacteria standards for waters listed ...

  • Progress on water data integration and distribution: a summary of select US Geological Survey data systems

    Critical water-resources issues ranging from flood response to water scarcity make access to integrated water information, services, tools, and models essential. Since 1995 when the first water data web pages went online, the US Geological Survey has been at the forefront of water data distribution and integration. Today, real-time and historical streamflow observations are available via web ...

  • Temporary forest pools: can we see the water for the trees?

    Abstract  Temporary waters, in general, are fascinating habitats in which to study the properties of species adapted to living in highly variable environments. Species display a remarkable array of strategies for dealing with the periodic loss of their primary medium that sets them apart from the inhabitants of permanent water bodies. Survival of individuals typically depends on exceptional ...


  • Nutrient Regulation on Streams: The Macrophyte Quandary

    ABSTRACTSince promulgation of the Clean Water Act in the 1970s and implementation of technology-based treatment requirements, such as secondary treatment for publicly owned treatment works, the nation’s water quality has improved dramatically. Current water quality concerns are no longer attributed to excessive loads of carbonaceous and nitrogenous biochemical oxygen demand. Rather, the largely ...

  • A conceptual framework for US EPA’s national exposure research laboratory

    The challenges of environmental protection range from understanding the potential risk associated with exposure of humans and ecosystems to a newly manufactured chemical, to minimizing human exposure to pathogens at public beaches, to linking human activities on the landscape to physical alterations of ecosystems. In the United States, there are more than 75,000 industrial chemicals that are ...

  • China in Talks to Join the OECD System for the Mutual Acceptance of Data in Assessment of Chemicals

    It has recently been reported that China is in discussions with the Organization for Economic Cooperation and Development (OECD) to become a provisional adherent to the Mutual Acceptance of Data (MAD) system. This would require China to accept data from safety testing of chemicals from participating countries generated under the MAD conditions and to establish a Good Laboratory Practice (GLP) ...

  • Use of Elcom and Caedym for Water Quality Simulation in Boulder Basin

    ABSTRACTThe growth of the Las Vegas Metropolitan area may eventually lead to increased wastewater discharges into Boulder Basin of Lake Mead (Figure 1). Boulder Basin has experienced several algal blooms over the last few years. As a result, alternate discharge locations and strategies are being investigated. Thus, studying the water quality in Boulder Basin becomes imminent in order to assist ...

  • Acid mine drainage treatment

    Acid mine/rock drainage is a rampant problem in the world today. The above photo depicts acid drainage at an abandoned mine in the Yukon Territory of northwest Canada. This mine shares a similar history to thousands of other mines throughout the world. It was in operation for six short years in the 1950’s, producing gold ore. Its profitability eventually failed and it was abandoned. In the ...
