Grab samples of indoor air near openings for soil gas entry into buildings. Interior Assessment Sub-slab soil gas data to assess COC concentrations potentially available for soil gas entry to the indoor air.
Vapor intrusion (VI) by volatile organic compounds (VOCs) in the built environment presents a threat to human health. Traditional VI assessments are often time-, cost-, and labor-intensive; whereas traditional subsurface methods sample a relatively small volume in the subsurface and are difficult to collect within and near structures. Trees could provide a similar subsurface sample where roots Cited by: 5. Lecture Groundwater Contamination. Key Questions. 1. What are some examples of point sources of groundwater contamination? Rainfall (or irrigation water) percolating into the soil transports nitrate in the soil to the surface of the aquifer (water table). • Public water systems are required to sample for nitrate on a regular basis.
Groundwater and Contaminant Hydrology has a range of research relating to the transport and fate of contaminants in soils and groundwater. The scope of the center includes: 1) the development of new sampling and site characterization techniques; and 2) other Author: Zulfiqar Ahmad, Arshad Ashraf, Gulraiz Akhter, Iftikhar Ahmad.

Slab soil gas and indoor ambient air of residential and commercial structures. In residential structures, this action level is parts per billion by volume (ppbv) in indoor air and 62 ppbv for sub-slab soil gas; the level assumes inhalation of the contaminant 24 hours per day, days per year for more than 30 years.
]. Exposure to some chemical vapors that migrate from groundwater through the soils and into a home can pose a greater risk than drinking those chemicals in tap water [Schuver ]. Intrusion of vapors from contaminated soil or groundwater into indoor air can cause fires, explosions, and acute, intermediate and chronic health Size: 1MB.

Evaluating Indoor Air Near VOC Contaminated Sites VOCs may be found in soil and/or groundwater due to spillage onto the ground, leaks from underground storage tanks and other types of discharges. near-slab soil gas testing and/or indoor air testing are usually required to determine whether vapor intrusion is occurring at a property.
We use the groundwater protection level and leachate reference concentration columns in the Groundwater Protection Values (GPV) soil cleanup table. The last column identifies the water standard used in the calculations, which are based on standards and methods established and employed by the Water Quality Control Commission.

Pressure Gradients across Building Foundations Vapor migration between the indoor air of a building and the subsurface soil gas can occur by advection when there is a pressure differential between the. Indoor air samples are generally collected from the lowest-level space in a building, typically a basement, during the heating season.
Indoor air samples may also be collected from the first floor of living space. Indoor air is believed to represent the greatest exposure potential with respect to soil vapor intrusion.

The model estimates risks of potential exposures to chemicals in indoor air based on actual groundwater or soil gas data, or it can be used to calculate target concentrations for specific chemicals in indoor air for various levels of risk.
groundwater, enters soil vapor (air spaces between soil particles), and migrates through building foundations into the building's indoor air. Acetone has also been found at low concentrations in outdoor air, which can also be a source of the chemical in indoor air.
Levels Typically Found in Air. Back to indoor air Indoor air quality concerns are often grouped into three categories: Defining an indoor air quality problem. This is normally the easiest type of indoor air quality problem to diagnose, but the fix can be difficult to achieve.
Indoor air as a source of VOC contamination in shallow soils below buildings Article (PDF Available) in Soil and Sediment Contamination 15(1) January with 97 Reads.
This document focuses on the collection of soil gas samples for assessing the significance of the subsurface-vapor-to-indoor-air exposure pathway. While soil gas collection is not the only means of assessing this pathway, soil gas data play a prominent role in recent guidance published by the.
contamination can result in the intrusion of vapour-phase contaminants into indoor air. If the soil vapour intrusion pathway is complete, there may be the potential for unacceptable health risks to building occupants as a result of inhalation of vapours.
Scope The focus of this guidance is sampling and analysis of soil vapour and indoor air,File Size: KB. The contamination status and health risks of benzene, toluene, ethylbenzene and xylene (BTEX) in air, soil, dust and groundwater were evaluated in a pesticide chemical region located in Hebei.
