Questions on STEM building test results?

November Update: Additional testing was completed in September with the results shared out in late September. District staff had planned to invite subject matter experts to answer any remaining questions, however, due to a number of scheduling conflicts questions are being taken online instead. Each submitted question will be shared with air quality experts with an answer provided on the Bella Vista website. After reviewing the test results, please submit any questions you may have by Nov. 22. 


Update, July 25: In consultation with third-party experts, district facilities staff have rescheduled the additional testing of the STEM building to occur after school starts so that the building is in full use. This will provide a full and accurate picture of the air quality in the facility when it is occupied by our teachers and students. Testing results will then be reviewed with state officials and shared with the Bella Vista community. 

These additional tests are being conducted out of an abundance of caution. All testing done on the facility (linked below) has shown no issue with the air quality. 


Air quality tests by independent third-parties have shown that Bella Vista’s STEM building exceeds all state and federal safety standards as well as the more stringent LEED standards of the US Green Building Council. The tests were done in response to concerns raised by four staff members about the building after carpeting was installed in the summer of 2018.

“The health and safety of our students and staff is a primary concern,” said San Juan Unified Superintendent Kent Kern. “While we have taken extensive steps to ensure the safety of Bella Vista’s STEM building, I have asked for another round of testing to be completed by a different firm so that our parents, students and staff can have full confidence in their classroom environment.”

Reports from tests already conducted on the facility as well as product statements for the flooring can be found via the links at the bottom of this article. In addition to the testing, district facility staff conducted a top-to-bottom cleaning of the building to remove any lingering construction dust, added materials to keep dust from falling from high areas of the building, and ensured the use of high-quality air filters in the building’s HVAC units and HEPA filters in the vacuums used for cleaning.

A new round of testing will be conducted to ensure that the first tests are consistent over time and to check for additional substances. Results are expected to be available in mid-July when a community meeting will be held for interested parties to hear directly from the testing firms and district staff. The meeting date, time and location will be posted to the school website when known.
