  • Bend CO Network Assessment 2003 PDF
    During the winter of 2003-2004 a study re-evaluating the current location of the carbon monoxide (CO) monitoring station in Bend Oregon was performed. This type of city-wide site assessment had not been conducted in Bend for a number of years. During that time Bend has experienced a large amount of population growth and changes to its traffic patterns. This study used a new portable CO survey sampler.
     
  • DEQ05-LAB-0031-TR PDF
    Practical Assessment of the Open Path Fourier Transform Infrared (OP-FTIR) for Ambient Air Quality Monitoring in Portland and Albany Oregon
    This report summaries DEQ's testing of the RAM 2000 Open Path FTIR during the summer of 2003 for use as an ambient monitor of air toxics compounds in the air. Testing was done for one month each at a site in NW Portland and one in Albany. The primary goal of the study was to evaluate the instrument and to gain some experience in its operation and capabilities. A secondary goal was to collect, if possible, some real-time ambient data on concentrations of air toxics in two Oregon communities. The data analysis for this study was done by Arcadis Inc.
     
  • Beaverton Particulate Matter Survey Study PDF
    This study was conducted in conjunction with the establishment of a new PM2.5 particulate sampling site in Beaverton on the property of Highland Park Middle School. Data from this study was used to determine if the Federal Reference Method (FRM) PM2.5 sampler was optimally placed to characterize neighborhood scale PM2.5 levels in Beaverton. PM2.5 measurements from the Highland Park Middle School sampler would determine if the site met the National Ambient Air Quality Standard (NAAQS) for PM2.5 particulates.
     
  • John Day and Canyon City Particulate Matter Survey Study PDF
    In the early 1990s the Oregon Department of Environmental Quality (ODEQ) Air Quality Technical Services Section developed a system to evaluate areas in Oregon regarding their potential to exhibit air quality problems. This evaluation system used information such as pollution sources, population, average temperatures, elevation, topography, and wind flow to determine whether a location was likely to develop air quality problems. Based on this system a PM10 survey was proposed for the John Day and Canyon City area of central Oregon. Of the 97 cities considered in the original evaluation matrix, John Day had ranked fifth for its potential to exceed National Ambient Air Quality Standard (NAAQS) for PM10. Additionally, in 1997 the US EPA promulgated a new fine particulate standard based on particles 2.5 microns or smaller (PM2.5). With this new standard in mind, a PM2.5 sampler was included in the study. Another fine particulate monitor, a nephelometer, was also part of the study. At the time the only air quality data available for the John Day area was that which had been generated by a nephelometer operated in the spring as part of the Forest Health Network, a joint DEQ-US Forest Service project. No other air quality studies had been conducted in that area.
     
  • Klamath Falls Particulate Matter Survey Study PDF
    This study was conducted in conjunction with the establishment of a new Federal Reference Method (FRM) PM2.5 particulate sampling site in Klamath Falls on Clinton Street at Peterson Elementary School. Data from this fine particulate study helped determine if the FRM PM2.5 sampler was optimally placed to characterize neighborhood scale PM2.5 levels in Klamath Falls. If the study validated the selection of the Peterson School site PM2.5 measurements from there would determine if the Klamath Falls area air shed meet the National Ambient Air Quality Standard (NAAQS) for PM2.5 particulates.
     
  • Salem Particulate Matter Survey Study PDF
    This study was conducted in conjunction with the establishment of a new Federal Reference Method (FRM) PM2.5 particulate sampling site in Salem on the property of Salem General Hospital on Medical Center Dr. NE, near D St. Data from this fine particulate study helped determine if the FRM PM2.5 sampler was optimally placed to characterize neighborhood scale PM2.5 levels in Salem. If the study validated the selection of the Salem General Hospital site PM2.5 measurements from there would be used to determine if the Salem area air shed meet the National Ambient Air Quality Standard (NAAQS) for PM2.5 particulates.
     
  • Portland Particulate Matter Survey Study PDF
    This study was conducted in conjunction with the establishment of a new Federal Reference Method (FRM) PM2.5 particulate sampling site in Portland, a longtime DEQ Air Quality monitoring site located at 5824 SE Lafayette St. Data from this fine particulate study would determine if the FRM PM2.5 sampler was optimally placed to characterize neighborhood scale PM2.5 levels in southeast Portland. PM2.5 measurements from this neighborhood site would determine if the SE Portland air shed meet the National Ambient Air Quality Standard (NAAQS) for PM2.5 particulates.
