Coal Dust Sampling & Monitoring

Updates

Metro Vancouver recently released a preliminary summary report of a study they conducted from June 2014 to May 2015  measuring particulate matter concentrations near railway lines.  The results showed that the fine particulate matter (PM10) levels from all sampling sites in Delta met the short-term (24-hour) ambient air quality objectives. Short-term elevated levels of particulate matter were very rare and the values were comparable to other areas in the regional airshed.   

Metro Vancouver plans to conduct further analysis on the collected data and will release the information when complete.  The preliminary summary report and the accompanying council report can be found here.

Overview

In response to continuing concerns from Delta residents, staff conducted independent monitoring to investigate the presence of coal dust in the community. Dustfall potential is greatest during dry periods with limited precipitation. Accordingly, the monitoring was conducted in July 2013 when five dustfall canisters were set out for the month to passively collect dustfall with the primary intent of determining the presence or absence of coal particles. Four locations were selected in Tsawwassen and one location was selected in the North 40 area north of Boundary Bay Airport - see the 2013 sampling locations map(6.4 MB).
