Description

The objectives of the 2014 investigation and monitoring program were to: Evaluate the potential for vapour migration in residences in the area; Assess exposure and risk to residents in the vicinity through direct measurement of indoor air; Investigate the effects of seasonality on potential vapour intrusion, soil vapour concentrations and presents of NAPL; Evaluate if attenuation and if possible biodegradation is occurring between the source and residents; and where possible, delineate the extent of NAPL in the vicinity of monitoring well MW10-6 and further characterize soil and groundwater conditions in this area.

Description

All monitoring sites were downwind of the CNRL natural gas well blowout, except Site G which was a background site. A one-hour AAAQO for hydrogen sulphide of 0.010 ppm was no exceeded. The maximum one-hour average for hydrogen sulphide of 0.001 ppm was measured at both Site G, the background site, and Site H. These were the only two sites were hydrogen sulphide was above the detection limit. The highest one hour total reduced sulphur concentration of 0.002 ppm as measured at Site E.
