PROJECT OVERVIEW:
Several sensitive receptors in close proximity to a soil removal project had a potential risk of exposure to both dust and organic vapors.
TECHNICAL HIGHLIGHTS:
Air monitoring equipment and weather enclosures were deployed at four locations adjacent to the project. A TSI DustTrak 8320 and a RAE Systems ppbRAE volatile organic compound monitor provided continuous, real-time concentration monitoring from each location. A low volatile radio network relayed real-time data to a centralized host computer via a RAE Systems AreaRAE network. An on-site weather station was installed for meteorological data collection. It was outfi tted with an RS-485 adapter to accommodate longer cables. The weather station was positioned on a roof adjacent to work areas and accessible from the fi eld offi ce directly via 50-foot cable interface. Both data collection methods were managed from the same laptop computer. Power for the air monitoring stations was a mix of AC/DC and solar based on availability. Field Data Solutions technicians traveled to the site for installation and client personnel training, as well as demobilization of equipment.
KEY OUTCOMES:
During the course of this multi-month project, the client was able to use the continuous, real-time data to alleviate concerns of workers and residents relative to a neighboring manufacturer. All data was collected, archived and used for project reporting and documentation.
