High Particulate Readings: BoulderAIR ECC Station

Readings suspected to be Caused by Instrument Error

The current high and sustained Particulate Matter (PM) 10 and PM 2.5 readings which began in the afternoon on July 25 at the Boulder AIR ECC monitoring station are being investigated.

At this time, Boulder AIR experts suspect that the readings are an instrument error and are not reflective of current air quality conditions.

Additional information will be provided following an investigation into the instruments by the Boulder AIR team.
