Levels of hydrogen sulfide gas are being monitored after a leak in Brantford Collegiate Institute’s geothermal system.

According to a statement from the principal, it happened during construction work at the school.

“Over the summer, work was scheduled to repair the school’s geothermal system, located in the sports field at the rear of the school. Low levels of hydrogen sulfide gas were detected during this work,” Principal Michael Degroote said.

Degroote said there are no immediate health risks to staff, students or the community and the Grand Erie District School Board is working with the Ministry of the Environment, Brant County Health Unit, an environmental consultant, and Brantford Fire Services is monitoring the levels.

Starting Sept. 20, a small portion of the system is being decommissioned to eliminate future risks. The work will include real-time monitoring of the levels of hydrogen sulfide during the decommissioning.

Officials expect minimal disruption and no significant impact to day-to-day operations.

The grass field is expected to be restored after the work is done.

Alternate arrangements for outdoor space will be available nearby, based on availability.
