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.

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.

soil testing

In tandem with soil testing conducted by Boulder County Public Health, BVSD worked with  BCPH to conduct testing at several school sites that were closest to the burn area, including Coal Creek, Fireside, Monarch Campus and Superior. Testing protocols were determined in consultation with BCPH and Colorado Department of Public Health and Environment (CDPHE). Each location was tested for 17 metals and asbestos at the surface. All tests at school sites were consistent with surrounding areas that were not impacted by the fire and do not pose a significant health risk. No further action is warranted at this time.


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. 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.
