The first step in creating a custom tailored vapor intrusion solution is a full understanding of all the variables that are contributing to the problem. Clean Vapor, uses a systematic approach that starts with a thorough building investigation, soil gas mapping of sub slab contaminants followed by vacuum field testing procedures and the application of proprietary models to determine the most efficient and effective solution.
Entry of soil borne contaminants into a building is the result of three primary variables:
1. The source strength of the contaminant in the soil.
2. The pressure differentials that draw the contaminants into the building.
3. The potential entry routes and pathways of vapors into the building.
Quantifying and understanding the relationship between these three variables and the effect they have on the final contaminant concentrations is the key to developing an effective mitigation plan. Proper diagnostics provide us with the necessary information to manipulate these influencing factors and correct the problem.
Vacuum field extension testing is a primary diagnostic tool used to understand the vacuum and airflow yields from the sub slab material. The results of the vacuum field extension testing allow us to mathematically predict the response of various vacuum inputs and determine the most effective locations for system suction points and the intensity of the vacuum that should be applied. Following these procedures ensures that the vapor intrusion problem is efficiently and effectively mitigated the first time.
