Abstract
The invention provides systems for perimeter air quality monitoring that can establish background levels of target contaminants in ambient air prior to initiation of remedial activities. The systems can develop remedial action levels that are protective of the public health for dust and vapors at the remediation property, and can monitor and document fence line ambient air levels of target contaminants during remedial activities. Accordingly the systems and process allow for evaluation of the need for dust or vapor control measures to reduce airborne containment levels to below levels of concern.
