  • Potential Environmental Impacts of Dust Suppressants: "Avoiding Another Times Beach" [PDF, 97 pp., 1.6 MB] - An expert panel summary. The purpose of this report is to summarize the current state of knowledge on the potential environmental impacts of chemical dust suppressants. Dust suppressants abate dust by changing the physical properties of the soil surface and are typically used on construction sites, unpaved roads, and mining activities.

  • EPA-NOAA Scientist to Scientist Meeting - On March 2-3, 2004, more than 100 EPA and NOAA scientists and managers met in Research Triangle Park, NC to discuss "Air Quality Research to Guide National Policy and Programs." This was the first in a series of meetings to be held under the EPA-NOAA Memorandum of Understanding (MOU) on Air Quality Research and the parallel Memorandum of Agreement (MOA) on Air Quality Forecasting signed by the Deputy Secretary of Commerce and EPA Administrator on May 6, 2003. The material presented reflects various subjects such as: Atmospheric Process Research, Atmospheric Model Evaluation Research, Air Quality Forecasting, Source Characterization and Source Emissions, and Special Issues in Air Quality Including Homeland Security.
  • An amendment for the Performance Verification Testing of Monitoring Systems for Air, Water and Soil assistance opportunity has been added.

  • Global Earth Observation System of Systems (GEOSS) - In July 2003, the United States hosted the Earth Observation Summit. The summit brought together 33 nations plus the European Commission to adopt a declaration that signified a political commitment toward the development of a comprehensive, coordinated and sustained Earth Observation System to collect and disseminate improved data, information, and models to stakeholders and decision makers. As part of that effort, EPA has provided state fact sheets detailing how Global Earth Observation System of Systems (GEOSS) could be beneficial to each state (Global Earth Observation System of Systems (GEOSS)).

  • Southwest Regional Gap Analysis Project: The Nevada Ecoregional Component - The Gap Analysis Program (GAP) is a national program of the U.S. Geological Survey (USGS) Biological Resources Division that maps the distribution of plant communities and selected animal species and compares these distributions with land stewardship to identify biotic elements at potential risk of endangerment. GAP is embarking on a second-generation effort to conduct the program at a regional scale, using a vegetation classification scheme applicable across the U.S., and using ecoregional units as the basis for classifying imagery. The program’s first formalized multi-state regional effort includes the five states (Arizona, Colorado, Nevada, New Mexico, and Utah) comprising the Southwest Regional Gap Analysis Project (SWReGAP).

NERL conducts research and development related to the exposure of people and ecosystems to a wide range of pollutants in the air, water, and soil, and to other environmental changes resulting from human activities at a wide range of scales including landscape alterations.
  • Updated Brewer spectrophotometer data for Everglades National Park, FL has been added to the UV NET site.

  • Detroit Exposure Aerosol Research Study (DEARS) - This site provides information about a research study that the U.S. Environmental Protection Agency is conducting in Detroit, Michigan. The study will help develop data that improves our understanding of human exposure to various air pollutants in our environment.
  • EPA Method 200.5 (PDF, 36 pp, 304 KB)- Determination of Trace Elements in Drinking Water by Axially Viewed Inductively Coupled Plasma - Atomic Emission Spectrometery.
  • Ecosytem Research Division's abstracts for upcoming and recent presentations.
    • Ecological Society of America Annual Meeting, Portland, OR, August 1-6, 2004.
      • Interactive habitat models for Mid-Atlantic Highland stream fishes. Abstract
        B. Rashleigh, R. Parmar, and J. Johnston.
      • Decision tool for riparian ecosystem managment in the Mid-Atlantic Highlands. Abstract
        J.M. Johnston, R. Parmar, K. Wolfe, P. Kinder, J. Newland, T. DeMoss, and D. Kemlage.

    • ASAE/CSAE Annual International Meeting, Ottawa, Canada, August 1-4, 2004
      • Development and validation of a mechanistic ground sprayer model. Abstract
        M.E. Teske, N.J. Ewing, N.B. Birchfield, and S.L. Bird.

  • Henry’s Law Calculations:
    The Henry’s law estimator has been enhanced to include more chemicals and an alternate method of calculation. The alternate method was developed by EPA Office of Solid Waste and Emergency Response (OSWER) for use in vapor intrusion assessment. Where required input data exist, both calculation methods give similar results. The OSWER method contains data for 97 chemicals, including many that are new to the calculators.
  • Vapor Intrusion Model
    Two versions of the Johnson-Ettinger (JE) model for vapor intrusion (VI) have been added to the calculator collection. These implement the approach taken in the OSWER VI guidance. Given a indoor air risk level, the first model back-calculates target soil gas and ground water concentrations. The second reverses the process by presuming a measured soil gas or ground water concentration and determines the associated risk. Both models implement a limited uncertainty analysis, because most of the parameters of the models are not measured in typical applications. Future work will include expanding the uncertainty analysis to include additional parameters.

  • EPA Technology for Mold Identification and Enumeration - the Primers and Probes for Target Species section has been updated.
  • Environmental Simulation and Modeling - a list of models currently under development, or in current use, by scientists at NERL's Environmental Research Division (ERD).
  • Nitrogen and Redox Speciation in Fresh-Water Systems - this page contains information about the collaboration between ERD and United States Department of Agriculture Agricultural Research Service (USDA/ARS)at the J. Phil Campbell, Sr., Natural Resource Conservation Center near Watkinsville, GA. This work is being conducted in support of ERD’s goal to develop predictive models for the transformation and fate of nutrients in the environment.
