At a large-scale soils removal and consolidation project, spanning three construction seasons, organic vapor and dust monitoring instruments were deployed to measure potential air impacts from project implementation.


With a self-healing mesh network, solar-powered fi eld air monitoring instruments capable of parts per billion level detections for vapors and dust concentrations were deployed. Instruments were protected in environmental enclosures at stations surrounding the project site. The real-time air monitoring data was transmitted through a wireless network to an on-site host computer in the fi rst phase, which was in place for approximately 14 months. In the second phase, the data was monitored remotely through a client specific, web-based user interface. FEI staff made routine site visits to maintain the system, which used dust meters, PIDs and a weather station.


Air vapor, dust concentration and weather data demonstrated that project implementation was within regulatory levels and nearby receptors were not adversely affected as a result. Data was provided for compliance reporting purposes.
