Marshall Fire Environmental Quality Information

BVSD is concerned about both the mental and physical health and well-being of our students and staff following the Marshall Fire. Providing a safe environment that is free of hazards at concentrations of concern is as important to BVSD as it is to our families and staff.  

Outdoor Air Quality Update | April 14, 2022

Air Quality

Air monitors have been installed on the eight schools affected by the fire and at other locations in the community. The monitors have been installed by Boulder County Public Health (BCPH) on BVSD buildings. The instruments monitor the level of ultrafine particulate matter in the air. Data is recorded and shared via an online platform. Schools will monitor the air quality information and use it with BVSD’s Outdoor Air Quality Guidelines to make decisions about conducting outdoor activities. Links to the website and other helpful resources are included below:

BVSD worked with our partners at Boulder County Public Health (BCPH) as well as our restoration contractor ATI and industrial hygiene consultant, Clark Seif Clark, Inc. for guidance related to providing a safe environment for students and staff in the areas affected by the Marshall Fire. For details of specific actions taken by BVSD during and immediately after the fire, see the letter from Clark Seif Clark regarding indoor environmental quality. 

BCPH has stated that it “strongly supports the resumption of classes at BVSD schools including those near the burn area, as well as the efforts the district has taken to ensure student safety.” The Colorado Division of Fire Prevention and Control inspected all buildings and deemed them safe to occupy.
