Summary A former spill site in the United States has three Soil Sensor locations within ~1 metre of each other. Though they are installed in separate boreholes, they are meant to reflect a gradient in gaseous emissions within the soil. The sensors are installed at 15, 30, and 45 ft (4.57, 9.14, and 13.72 m) belowground. Here we compare two approaches to calculating NSZD: the first is our ...

Site Challenge Workers at a facility noted transient odours and were concerned that vapours were entering the workspace from a nearby source. The client and their team hypothesized that the transient vapour entry might be linked to site activities, such as deliveries on-site. The client's consultant had conducted soil vapour sampling using a Photo-lonization Detector (PID) over the 2022 calendar ...
