Description

This report presents background information and justification for the performance specification standards developed as part of the revision and update of the Alberta Air Monitoring Directive. Air Resource Specialists, Inc. was contracted by Alberta Sustainable Resource and Development to assess available technologies for continuous ambient air quality and meteorological measurements. The information was used to develop and update specification standards sheets containing minimum performance specifications for the associated continuous analyzers.

Report on Canada Creosote site - North Bow screening level risk assessment update

Description

This follow-up investigation and screening level HHRA update was completed to address data gaps and recommendations outlined in the HHRA previously conducted by Golder in 2010 and 201.... More ≫

Description

This follow-up investigation and screening level HHRA update was completed to address data gaps and recommendations outlined in the HHRA previously conducted by Golder in 2010 and 201. Specifically, the objective of this investigation was to collect additional seasonal groundwater and soil vapour data at the site, and to update the previous HHRA based on this new data. The soil vapour sampling events carried out as part of this investigation targeted times of year when groundwater levels were expected to be at their approximate lowest and the vapour risk was assumed to be at its approximate highest.

Assessment of recent changes in water quality of the Bow River downstream of the Canada Creosote site in Calgary

Description

These sampling results provide no evidence that the target compounds occur regularly in river water along the left bank (facing downstream), on the north side of the river. Contaminant movement... More ≫

Description

These sampling results provide no evidence that the target compounds occur regularly in river water along the left bank (facing downstream), on the north side of the river. Contaminant movement from the remaining pool of DNAPL in the river bed close to the right bank (facing downstream) remains the likely source of compounds detected on that side of the river downstream from the Canada Creosote site.

Air quality monitoring in the vicinity of a CNRL well blowout : February 25, 2010 to March 9, 2010 summary report

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... More ≫

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.

Description

Risk for soil contamination exists at industrial plants that have a potential for release of substances to the environment. Soil contamination may also become a source of contamination for groundwater, surface water and air. Remediation costs often increase sharply when soil contamination spreads to other media. This directive establishes the regulatory requirements and professional guidance which are needed to ensure that the soil resource and associated environmental media are protected at industrial sites.

Description

Alberta Environment commissioned Dr. John Neil Cape from the Centre for Ecology and Hydrology at the Edinburgh Research Station in the United Kingdom to conduct a review of current air and deposition monitoring in Alberta and provided recommendations for future network development. The review was conducted to support the development of a new air monitoring strategic plan for Alberta, and considered factors such as existing air monitoring in Alberta and future air emission scenarios.

Description

Air quality surveys in seven communities around Lake Wabamun were conducted between November 2004 and October 2007. The study was conducted to collect general air quality information. The Mobile Air Monitoring Laboratory was used to collect a total of 90 hours of data. The current study is a follow up to one conducted in 2000/01. With the exception of larger particles, concentrations measured in 2000/01 were comparable to those observed during the current study. Large particles measured during the 2000/01 study in part were likely due to road and wind blown dust.
