Rail Line Sampling Site
The Rail Line Sampling Site is located at the Eastmoreland Golf Course, adjacent to the railroad tracks. This site has been operating since March 2014 and is capable of measuring black carbon, particulate matter, and carbon dioxide.
Below are monthly average concentrations for pollutants measured compared to the EPA National Ambient Air Quality Standard
EPA NAAQS (http://www.epa.gov/air/criteria.html)
PM10: 150 ug/m3 (daily)
PM2.5: 12 ug/m3 (annually)

* Only 6 days worth of data (6/1-6/6) due to required instrument calibrations
** Incomplete data set. Averages calculated from 6/13-6/20, 6/27-6/30
August: DustTrak collevted data from 8/1-8/11, 8/21-8/25
September: DustTrak collected data from 9/10-9/26. Currently being calibrated due to filter change.
Aethalometer missing data 9/1-9/10
% DustTrak calibrated with TEOM from DEQ. Corrections applied to all data
Rail Line site is no longer sampling and will be redeployed at a different site upwind of the Rail Yard
