Where a structure has a combination of concrete and earthen floors sub-slab soil gas sampling combined with indoor air sampling of the basement/crawlspace should be considered. - Indoor air quality-related research which included multizone building airflow simulation using CONTAM in an effort to better understand and quantify the spread of airborne SARS-CoV-2 in office . The intent of the guidance is to: (1) offer a methodology to screen out sites where vapor intrusion is unlikely, thereby (2) identify sites where there is a potential for vapor intrusion, thereby requiring further investigation. Mold growth can occur in any indoor space and is often caused by . Sampling instruments were placed in the main living area of each participating home and generally located in close proximity to each other at a height of about 1.0-1.5m. In most cases, if visible mold growth is present, sampling is unnecessary. EMS typically recommends a minimum of five air samples be collected from the indoor environment, even in small single-story residential homes. Lack of knowledge regarding indoor air quality issues and cost considerations tend to contribute to the omission of indoor air sampling and evaluation. Indoor air quality may varyon a daily basis; therefore, sampling one day may not show a problem even though sampling a day later might show contamination.

It is important to consult with the laboratory when planning a soil gas, sub-slab, or indoor air sampling event to ensure that the reporting limits (i.e., Practical Quantitation Limits, PQLs) for constituents of concern will be low enough to measure concentrations of interest. Update The subsurface source can either be contaminated groundwater or contaminated soil which releases vapors into the pore spaces in the soil. The Indoor Air Quality Questionnaire and Building Inventory Form in Appendix B of the final guidance (as revised March 2007) is provided to aid with the evaluation of indoor air sampling results by collecting pertinent building and household product information that may influence soil vapor intrusion and indoor air quality. Select three (3) locations for indoor air samples - within primary living/work areas, near identified vapor entry points, or near suspected hotspots.
