Under what conditions will any site with soil-gas sampling be classified?

The classification of any site with soil-gas sampling as RBDM (Risk-Based Decision-Making) Closure is grounded in the specific context of soil-gas sampling and its implications for site assessments related to contamination. Soil-gas sampling is often employed to evaluate the presence of volatile organic compounds (VOCs) or other hazardous substances in the soil and the potential risk they pose to human health and the environment.

When a site is classified as RBDM Closure, it indicates that the closure process is taking into account the risk associated with any detected contaminants, which often includes utilizing soil-gas sampling results to inform the decision-making process. This approach emphasizes a tailored response based on the actual risks posed, rather than a one-size-fits-all method. It allows for specific strategies to be developed that can lead to a closure that reflects the actual conditions on-site and the associated risks.

Other classifications like Site Evaluation, Standard Closure, or Environmental Compliance may relate to broader processes but do not specifically focus on soil-gas sampling results and their interpretation within a risk management framework. Thus, RBDM Closure is specifically designed to incorporate site-specific data, including the results of soil-gas sampling, into closure decisions.
