Noorvik PM 10 data summary
Noorvik has sampled for more than one year. Between January 1, and December 12, 2004 the
sampler recorded 10 exceedances of the National Ambient Air Quality Standard (NAAQS) for
PM10 (dust). The NAAQS health standard is set at 150 μg/m3. The overall average dust
concentration for the year was measured at 79 μg/m3 (including the double run data). The median
concentration is 13 μg/m3. This indicates that the air quality for most of the year is good, but that
during periods of dust events the concentrations are often very high. The average exceedance day
shows a concentration of 322 μg/m3 more than double the NAAQS.
Data capture for the year was above 85%, based on a 1/6 sampling schedule. EPA requires at
least a 75% data capture for EPA funded monitoring projects.
