This study demonstrates how CONTAM and Visual Sample Plan (VSP) software can simulate airborne contaminant dispersion to develop effective sampling strategies for response and recovery after a biothreat agent release.
Area of Science:
- Environmental Science
- Computational Modeling
- Risk Assessment
Background:
- Real-world biothreat agent release simulations are limited.
- Computer simulations offer a method to explore diverse release scenarios.
Purpose of the Study:
- To validate response and recovery sampling technologies.
- To demonstrate the combined use of CONTAM and VSP for sampling plan development.
Main Methods:
- Simulated biothreat agent releases at Idaho National Laboratory (INL).
- Utilized CONTAM software for virtual contamination modeling.
- Employed Visual Sample Plan (VSP) for sampling strategy analysis.
Main Results:
- CONTAM simulated contaminant dispersion under various scenarios.
- VSP evaluated the effectiveness of sampling strategies based on CONTAM outputs.
- Demonstrated the synergistic use of CONTAM and VSP for sampling plan optimization.
Conclusions:
- CONTAM and VSP effectively support sampling plan development for airborne events.
- Simulation-driven identification of priority zones enhances sampling strategies.
- This integrated approach aids response and recovery planning for chemical, biological, radiological, or nuclear events.

Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...
01:18Sampling Methods: Sample Types
Solid samples include a variety of substances, such as sediments from water bodies, soil, metals, and biological tissues. Two standard methods for extracting sediments from water bodies are grab sampling and piston coring. Grab sampling involves using a device to collect a discrete sediment sample from the bottom of a water body with minimal disturbance. Grab samples do not always represent the entire area due to...
