Exposure Research: Sustainability

Methods, Models, Tools and Databases

Methods

  • ReVA
    EPA's Regional Vulnerability Assessment (ReVA) program is an approach to regional scale, priority-setting assessment by integrating research on human and environmental health, ecorestoration, landscape analysis, regional exposure and process modeling, problem formulation, and ecological risk guidelines.

Models

  • CMAQ Model
    CMAQ is an air quality model and software suite designed to model multiple pollutants at multiple scales. CMAQ allows regulatory agencies and state governments to evaluate the impact of air quality management decisions, and gives scientists the ability to probe, simulate, and understand chemical and physical interactions in the atmosphere.

  • Positive Matrix Factorization (PMF) Model
    EPA's Positive Matrix Factorization (PMF) Model is one of several receptor models developed by EPA scientists that provide scientific support for current ambient air quality standards and implementation of those standards by identifying and quantifying the relative contributions that various air pollution sources contribute to ambient air quality in a community or region. Users of EPA's PMF model provide files of sample species concentrations and uncertainties which the model uses to calculate the number of sources types, profiles, relative contributions, and a time-series of contributions.
  • Unmix 6.0 Model
    EPA's Unmix 6.0 Model is one of several receptor models developed by EPA scientists that provide scientific support for current ambient air quality standards and implementation of those standards by identifying and quantifying the relative contributions that various air pollution sources contribute to ambient air quality in a community or region. Users of EPA's PMF model provide files of sample species concentrations and uncertainties which the model uses to calculate the number of sources types, profiles, relative contributions, and a time-series of contributions.

  • ReVA Tools and Projects
    EPA's Regional Vulnerability Assessment (ReVA) program is designed to create the methods needed to understand a region's environmental quality and its spatial pattern. Impacts of human activities are not uniformly distributed across landscapes and regions (defined here as a multi-state area) and are often interacting in complex ways.
  • ReVA - Environmental Decision Toolkits under development
  • Watershed Health Assessment Tools Investigating Fisheries (WHATIF)
    WHATIF is software that integrates a number of calculators, tools, and models for assessing the health of watersheds and streams with an emphasis on fish communities. The toolset consists of hydrologic and stream geometry calculators, a fish assemblage predictor, a fish habitat suitability calculator, macro-invertebrate biodiversity calculators, and a process-based model to predict biomass dynamics of stream biota. WHATIF also supports screening analyses, such as prioritizing areas for restoration and comparing alternative watershed and habitat management scenarios.
  • Tribal-Focused Environmental Risk and Sustainability Tool (Tribal-FERST)
    EPA scientists are collaborating with tribes and partners to develop the Tribal-Focused Environmental Risk and Sustainability Tool (Tribal-FERST), designed to provide the best available human health and ecological science to tribes across the country. T-FERST is a community mapping, information access, and assessment tool designed to help assess risks and assist in decision making within tribal communities.
  • Community-Focused Exposure and Risk Screening Tool (C-FERST)
    In an effort to enhance community-based cumulative risk assessments, EPA exposure scientists have developed the Community-Focused Exposure and Risk Screening Tool (C-FERST) - a community mapping, information access, and assessment tool. C-FERST is expected to increase the availability and accessibility of science for risk ranking and understanding the environmental health consequences of community based decisions. It will incorporate the latest research estimating human exposures to toxic substances in the environment. In doing so, C-FERST will assist communities with the challenge of identifying and prioritizing environmental health issues and potential actions.
