Riverside, Wisconsin — Riverside University High School Will Delay Opening Due to Chemical Spill
Riverside University High School in Milwaukee will remain closed on Tuesday, September 2, following a chemical spill that prompted immediate safety precautions. The closure affects students, staff, and families just before the start of the academic year, which is typically scheduled to begin on September 2 for most district schools.
Immediate Actions and Safety Measures
The decision to close the school was made by district officials to prioritize the health and safety of everyone on campus. Parents received official notifications from Milwaukee Public Schools (MPS) informing them of the closure and explaining the circumstances. Although initial tests showed that the school’s air quality had improved after the spill, cleanup efforts were still ongoing. As a result, a few classrooms at Riverside High remain closed as contractors work to complete the cleaning process.
Details of the Incident
The incident involved a leak or spill of dangerous chemicals, with investigators focusing on the possibility that old science equipment containing mercury may have contributed to the problem. While the exact cause of the spill is still under investigation, district officials stress that all necessary safety checks have been performed to ensure the environment is safe for reopening. The building has cleared initial air quality tests, but some cleanup activities remain to fully address the issue.
Staff and Student Expectations
Despite the school closure, staff members are expected to report to work on Tuesday, September 2, to assist with ongoing cleanup and safety assessments. Meanwhile, students are scheduled to return to class on Wednesday, September 3, barring any unforeseen developments. The delay aims to confirm that all areas of the school are safe and free of any lingering hazards before students resume their learning activities.
Investigation and Ongoing Cleanup
District officials are actively investigating the details of the spill, including how the old mercury-containing equipment may have contributed to the incident. While the investigation continues, district representatives have emphasized transparency and diligence in completing the cleanup process. They also appreciate the patience and understanding of students, families, and staff during this unexpected disruption.
Background on School Year Start
The disruption comes just days before the start of the new school year for Milwaukee Public Schools, which usually begins on September 2. The delay at Riverside High has caused concern among families, but officials affirm that resuming classes on September 3 is the safest course of action. District leaders continue to monitor the situation closely, ensuring all safety protocols are followed before students return to the classroom.
Looking Ahead
As cleanup efforts conclude and investigations progress, authorities plan to update the school community about the progress and estimated timeline for full reopening.
