RespondFast^® Real-Time Monitoring System: Perimeter Ambient Air Monitoring Program, Confidential Client, MWOU5 Site

A confidential client contracted WESTON to manage the excavation of the MWOU5 site in Danville, Pennsylvania. As part of the excavation activities, WESTON performed a perimeter ambient air monitoring program to ensure that off-site migration of fugitive emissions from excavation activities did not adversely affect neighboring areas. The monitoring program included multiple stations around the perimeter of the excavation site for the duration of the excavation activities, approximately 9 months.

To further protect the community, WESTON installed the RespondFast^® system to monitor the site boundary in real time. This system automates data collection from sensors (air, water, soil, etc.) and allows real-time retrieval by sending data over a wire, wireless, satellite, or Web connection to a secure Internet database. A six-station, automated wireless perimeter air monitoring system and a meteorological tower continuously measured volatile organic compounds and particulate matter (PM) at the remediation site, and the RespondFast^® system established notification criteria for exceedances of specified PM levels. The RespondFast^® system sent an automated e-mail message to cell phones and pagers to immediately notify designated individuals of excursions, locations of excursions, and the PM reading that triggered excursions. This feature enabled WESTON to manage air quality to meet the standards protective of the nearby residential community.

RespondFast^® data were continuously loaded to a database, resulting in real-time tracking and reporting of the levels of PM at the excavation site. Reports generated through these systems were queried through the TeamLink^® Web interface on a real-time basis, providing key decision makers at the MWOU5 site and WESTON continuous access to data.
