We want to inform our school community that recent testing has identified elevated radon levels in certain areas of Martin Warren Elementary School.
What is radon?
Radon is a naturally occurring, colorless, odorless gas that comes from the breakdown of uranium in soil and rock. It can enter buildings through small cracks or openings in the foundation. Long-term exposure to high levels of radon can pose health risks.
What we are doing immediately:
The safety of our students and staff is our highest priority. In response to these findings, we have:
Moved all staff and students out of the basement rooms at Martin Warren Elementary
Conducting confirmatory testing to verify results
Consulted with environmental health experts and state/local authorities
Increased ventilation in impacted spaces
Begun planning for mitigation measures (such as radon reduction systems)
Schedule radon testing for all district buildings within the safety plan
Next steps:
After completing comprehensive testing across the entire building, we will have a clear understanding of where mitigation is needed. We are working with a qualified radon mitigation contractor to design and install a radon mitigation system. We will also conduct additional testing after installation to ensure these solutions are fully effective.
Ongoing safety:
We will continue regular monitoring of radon levels
All actions are being taken in accordance with EPA guidelines. These guidelines recommend that all schools be tested, regardless of geographic location or building age. Then, facilities must implement solutions when levels exceed 4 pCi/L (picocuries per liter).
We will keep families and staff informed throughout this process
What this means for students and staff:
At this time, we are taking all appropriate precautions to ensure that our school environment remains safe. Short-term exposure to elevated radon levels presents a low immediate risk, but we are acting promptly to address the issue and minimize any long-term concerns.
Questions or concerns:
If you have questions, please contact Dr. Troy Marnholtz at 660-747-7823. We are committed to transparency and will provide updates as we move forward.
