Description

Alberta Environment has completed the second annual assessment of particulate matter (PM) and ozone data as promised under the Clean Air Strategic Alliance (CASA) Particulate Matter and Ozone Management Framework. The assessment compares outdoor levels of fine particulate matter (PM2.5) and ozone data to action triggers defined by the CASA Framework. Action levels have been assigned to air monitoring stations in Alberta based on the procedure defined by the Canada Wide Standards (CWS) and CASA Framework. The results of the assessment show that PM2.5 and ozone levels at all monitoring stations were lower than the CWS exceedance trigger based on data from 2002 to 2004 after backing out or removing episodes that were primarily caused by natural, background or trans-boundary influences. However, the assessment results do show that ozone levels in some areas of the province are approaching CWS levels and therefore air quality management plans need to be developed.

Description

Natural Resources Service of Alberta Environment has monitored the water quality of Sylvan Lake each year since 1983, except for 1991 and 1998. This long period of record provides an excellent database from which to determine whether water quality in the lake is changing. Staff of Sylvan Lake/Jarvis Bay Provincial Park collect the samples, Monitoring Branch processes them, and Water Sciences Branch interprets the data. This brief report updates information sent to Alberta Parks in 1996.
