EON Products offers several types of soil vapor sampling systems and equipment to help you collect and sample vapor from shallow depths, either by using temporary soil probes or permanent soil gas points. Soil vapor or gas is the air found in the pore spaces between soil particles. It is the natural process of wearing away of the topsoil, but human activities have accelerated the process.

A process for evaluating the vapor intrusion pathway during a remedial investigation and feasibility study (see WAC 173-340-350). Current and potential exposures are considered when evaluating vapor intrusion at a site that has documented subsurface sources of volatile chemicals.

Key assumptions to the risk determination are the risk level, the toxicity of the contaminant, and the exposure factors. EPA's Vapor Intrusion website contains basic information about vapor intrusion, technical and policy documents, tools and other resources to support vapor intrusion investigations.It also provides access to technical reports focused on topics such as conceptual model scenarios for the vapor intrusion pathway and mitigation approaches for vapor intrusion. Executive Summary . 2.3 Vapor Intrusion (VI) Definition Vapor intrusion (VI) is the migration of volatile chemicals from subsurface soil or groundwater into inhabitable buildings. Vapors in soil gas are shown to enter buildings through cracks in the foundation and openings for utility lines. The Phase II ESA, also referred to as a “subsurface investigation” or more commonly “site investigation,” typically consists of collecting a series of The Sites Management Section maintains a variety of guidance documents intended to assist property owners, prospective purchasers, environmental consultants, and other interested parties in the remediation of contaminated properties. About If contaminated vapor enters a building, indoor air quality may be affected. / ɪnˈtruː.ʒ ə n / C2 an occasion when someone goes into a place or situation where they are not wanted or expected to be: They complained about excessive government intrusion (= unwanted involvement) into their legitimate activities. Irrigation of soils is directly proportional to decrease in soil salinity (Cetin and Kirda, 2003). Fax: (770) 978-8661 However, exposure to VOCs does not mean health effects will occur. Vapor intrusion is a complex phenomenon and is different in some important ways from contamination in soil and groundwater. However, the permeable layer had a minor effect on CH(4) emissions and CH(4) oxidation in the cover soil when the ratio of the gas permeability of the cover soil to the mean refuse gas permeability ≤ 0.05. © 2021 EON Products, Inc. by Springwood Marketing. endstream endobj startxref ‘saline alluvial soils’. Recommended references for indoor air, crawl space, sub-slab and ambient air sampling, and vapor intrusion … Health effects depend on various factors, including inhalation exposure, the length of exposure, the frequency of exposure, and the toxicity of the chemical. %%EOF recovery.

These commonly used products may find their way into the soil from industrial spills, leaking underground storage tanks and pipes, illegal dumping, and improper drum storage. ‘Strong winds remove the fertile top soil and seawater intrusion during the rains leaves the soil and water saline.’ 1.1 Medicine (of a solution) containing sodium chloride and/or a salt or salts of magnesium or another alkali metal. Resources b. any igneous rock formed in this way. Because of a difference in pressure between the vapor in the soil and the interior of the building, the vapor enters buildings through cracks in slabs or basement floors and walls, as well as through openings around pipes and electrical wires. • A wide range of sampling, measuring and environmental monitoring equipment and supplies. VOCs are the most likely group of chemicals found in soil vapor. • High-quality, well-maintained used environmental equipment. Soil vapor, also referred to as soil gas, is the air found in the pore spaces between soil particles (Figure 1.1). Vapor Intrusion (VI) is defined in the Investigation and Remediation of Contaminated Properties Rule (IRule) as the migration of volatile and semi-volatile chemicals from contaminated environmental media into a structure.
