Riverside, Milwaukee — School Opening Delayed at Riverside University High School Due to Chemical Spill
The start of the academic year at Riverside University High School in Milwaukee has been postponed following a chemical spill that occurred on Monday, September 1. The incident prompted officials to suspend classes scheduled for Tuesday, September 2, as cleanup and safety assessments continue.
School Closure and Rescheduled Opening
In a communication sent to parents and guardians, Milwaukee Public Schools (MPS) announced that students should not report to Riverside University High School on Tuesday, September 2. Instead, the school will now open for students on Wednesday, September 3. The delay means the school’s first day of classes has shifted by one day, impacting the initial schedules for students and staff.
Safety Measures and Air Quality Testing
Despite the spill incident, authorities have conducted air quality tests within the school. Results indicated that the air is safe for students and staff, which allows for the reopening of most areas of the campus. However, some classrooms remain closed as cleanup efforts are still underway to fully address contamination, particularly in areas where the spill occurred.
Investigation into the Cause of the Spill
School officials, including Deputy Superintendent Eduardo Galván, have indicated that an ongoing investigation is examining the possible causes of the chemical spill. Preliminary findings suggest that old science equipment containing mercury might have been involved, raising concerns about outdated laboratory materials and safety protocols.
Staff Responsibilities During Closure
While students are not expected to attend school on September 2, school staff are still required to report to work. This allows maintenance and safety teams to complete necessary cleanup activities and further assessments to ensure the environment is safe for students and staff moving forward.
Impact on Overall School Year Schedule
The delay at Riverside University High School is notable because most other Milwaukee schools are scheduled to open on September 2 as originally planned. The incident has caused a temporary disruption specifically tailored to this school’s opening, but district officials clarify that most schools will begin their academic year as scheduled.
Background Context
Riverside University High School is one of Milwaukee’s longstanding educational institutions, serving a diverse student body. Incidents involving older science tools are not uncommon in schools with historical laboratories, but authorities emphasize the importance of strict safety reviews when such problems arise. This chemical spill underscores ongoing efforts to modernize facilities and improve safety standards across the district.
Next Steps and Future Outlook
District officials plan to conduct further testing to confirm that all areas of the school are free of hazardous substances before reopening without restrictions. They have also reiterated their commitment to maintaining a safe learning environment and providing timely updates to families and staff as investigations proceed. The school community is awaiting a final clearance for students to return for classes on September 3.
