Fourteen Minster High School student-athletes were taken to area hospitals after a chemical malfunction at the village pool on the morning of Tuesday, June 2, 2026. The Minster Swimming Pool is temporarily shut down while staff and emergency responders sort out what went wrong and monitor everyone who was affected.
What Officials And Local Reports Say
According to the Cincinnati Enquirer, about 20 members of the Minster swim team were in the water when the incident unfolded, and 14 of them were transported to local hospitals to get checked out. Local coverage notes that several swimmers were coughing and having trouble breathing, and radio traffic from the scene described a strong chemical smell. WCSM Radio reported that mutual aid was called in because of the high number of patients.
Officials: Pump Failure Sent A Concentrated Slug Of Chlorine
Village officials and local reports say the trouble started when a pool recirculation pump stopped working, but the chlorine feed kept running. When the system eventually kicked back on, a concentrated slug of chlorine went into the pool water. In coverage of the village press release, The Lima News (republished on EMS1) quoted Village Administrator Donald W. Harrod as saying, "their well-being remains our primary concern, and we are continuing to monitor the situation closely."
Emergency Response And Hospital Evaluations
Minster Area Life Squad, New Bremen EMS, and other local units responded to the pool, and multiple fire and rescue agencies helped handle the number of swimmers needing evaluation, according to local reporting. Hospitals named in those reports include Joint Township District Memorial Hospital and Wilson Health, though officials have not released detailed information on patient conditions. WCSM Radio also published a rundown of which agencies and hospitals were involved during the incident.
Chlorine Risks And How These Events Are Prevented
Chlorine, which can form irritating gases when it is mishandled, can trigger coughing, chest tightness, and shortness of breath at high exposure levels, according to federal guidance from the CDC. CDC analysis of pool-chemical injuries shows thousands of emergency-department visits linked to pool chemicals and recommends strong operational safeguards and use of the Model Aquatic Health Code to help prevent similar incidents. Those prevention steps are detailed in the CDC MMWR analysis.
What’s Next
The Village of Minster has said the pool will stay closed "until repairs have been completed and all systems have been thoroughly inspected and determined to be operating safely," and that it is working with the appropriate agencies while maintenance crews troubleshoot the equipment. The village also plans to post reopening updates on the Minster Pool Facebook page and share more details as they are confirmed, and its press release appears in local coverage. WLIO carried the village’s statement.
Officials said they intend to release additional information as the review continues. Families worried about symptoms after possible chemical exposure have been advised to seek medical care.
