  • A New Freshwater Monitoring Center. (1041)

    The Western Center for Monitoring and Assessment of Freshwater Ecosystems is dedicated to freshwater bioassessment and monitoring. It is supported by the US Environmental Protection Agency, the US Bureau of Land Management, the US Forest Service, and Utah State University and is directed by Dr. Charles Hawkins of Utah State University’s Department of Aquatic, Watershed, and Earth Resources. The primary mission of the Center is to facilitate the development and implementation of scientifically sound methods for monitoring and assessing the condition of aquatic resources in the western United States. Our main goal is to aid federal, state, tribal, and local land and water management agencies in meeting the biological monitoring and assessment objectives required by the United States Clean Water Act and other federal and state environmental legislation. Other goals of the Center are to facilitate communication and collaboration between tribal, state, and federal agencies with respect to their common monitoring and assessment needs; provide technical guidance through workshops and other types of outreach education; and serve as a repository and clearing house for data and information related to aquatic monitoring. Please visit our web site at www.cnr.usu.edu/wmc. The web site provides an entry to the bioassessment literature, a brief overview of bioassessment concepts and methods, and a section describing the theory and application of RIVPACS-type predictive models. The Center also supports web-based software to both run existing state and regional models and custom-build your own models. Access to the software is available by obtaining a username and password. Interested individuals should visit the predictive model section within the web site for information regarding access to the software. (11/26/2004)

  • ECOTOX Database System - USEPA (858)

    The ECOTOXicology database is a source for locating single chemical toxicity data for aquatic life, terrestrial plants and wildlife. ECOTOX integrates three toxicology effects databases: AQUIRE (aquatic life), PHYTOTOX (terrestrial plants), and TERRETOX (terrestrial wildlife). These databases were created by the U.S. EPA, Office of Research and Development (ORD), and the National Health and Environmental Effects Research Laboratory (NHEERL), Mid-Continent Ecology Division.

  • Central Plains Center for BioAssessment (1003)

    The Central Plains Center for BioAssessment (CPCB) is a non-regulatory and non-management research organization nested within the Kansas Biological Survey (KBS). The CPCB was established as a center of biological expertise and as a scientific resource for the Central Plains and the United States Environmental Protection Agency (USEPA) Region 7. The Center's goals are to:

    • Facilitate the exchange of information between scientists, government officials, and the public on issues of water quality
    • Provide scientific expertise on such issues as taxonomy, aquatic ecology, data storage, data analysis, and study design
    • Collaborate on scientific studies such as the development of nutrient criteria and biocriteria
    • Maintain open communications within the region via a web page and list server
