Chemical Pathways in the Environment (18)
Problem: Predict chemical movement and persistence in the environment to aid in sensor placement and data interpretation
Project Activity Scope (from Technical Overview Chart): Interaction mechanisms through Measurement & Analysis System Applications
PNNL Solution:
- Used chemistry, meteorology, and local terrain knowledge to understand chemical form/location/persistence
- Developed/validated efficient models to predict the local dispersion, diffusion, and degradation of released chemicals
- Successfully predicted chemical fate and transport effects at various field sites
Capabilities Employed to Meet Client Needs: Regional-scale and watershed risk analysis; modular risk analysis; multimedia model development using geographical information systems; vadose zone, groundwater and surface water pathway analysis; ecological risk assessments; climatology; hydrology and contaminant property transport database development; human risk/health consequence analysis; and software model development.
