Radon Testing

South Washington County Schools is one of the 53 school districts in the state who have tested for radon since 2012 and have found no concerns in any of our buildings. District 833 began testing its school buildings in 2015 and completed tests for all buildings in 2018. When the district started its first round of testing, its plan met industry standards of taking samples from various high-frequency, ground level rooms. Earlier in 2018, the decision was made to expand the testing to include all high frequency rooms, not just samples from some rooms. This will be the standard into the future as buildings are retested on their scheduled timelines. 

We are committed to being fully transparent in this issue, as the safety of our staff and students is our top priority. Below are district reports on radon testing and results that were given to the Minnesota Department of Health. Each report explains when and where testing was done at each building. The reports also include the level of radon detected. The state requires schools to take corrective action for any room that tests above 4pCi/L or picocuries per liter. No District 833 schools have tested above this threshold.
