Richmond, California — A Bay Area high school will remain closed indefinitely after environmental testing detected tetrachloroethylene (PCE) vapors on campus, prompting school officials to halt all access while state inspectors determine whether the site is safe for students and staff.
The unexpected closure comes just as families prepare for the start of the new academic year, leaving many wondering when students will be able to return to classrooms.
Toxic Vapor Detected During Environmental Testing
According to the West Contra Costa Unified School District (WCCUSD), Kennedy High School in Richmond, California, was closed after vapor testing identified elevated levels of tetrachloroethylene (PCE) on the campus.
District officials said the decision followed preliminary environmental testing and was made before students returned for the new school year.
As a precaution, no students or staff are currently allowed on campus until additional inspections and testing have been completed.
The school is located approximately 20 miles northeast of San Francisco.
Superintendent Explains Why the School Was Closed
In a message sent to the school community, Superintendent Cheryl Cotton acknowledged that the timing of the closure is especially concerning as the beginning of the school year draws near.
She explained that while the California Department of Toxic Substances Control (DTSC) has indicated that preliminary findings do not suggest an immediate threat to health or safety, officials still need more data before declaring the campus safe.
According to Cotton, the district chose to close the school “out of an abundance of caution” until inspectors complete their evaluation.
She also emphasized that ensuring the safety of students and employees remains the district’s top priority.
What Is Tetrachloroethylene?
Tetrachloroethylene (PCE) is an industrial chemical commonly used in dry cleaning and metal degreasing operations.
According to the U.S. Centers for Disease Control and Prevention (CDC), exposure to the chemical can affect several parts of the body, including the:
- Nervous system
- Liver
- Kidneys
- Reproductive system
Health officials also warn that exposure during pregnancy may pose risks to unborn children.
The CDC further notes that long-term exposure may increase the risk of developing certain types of cancer, although the level of risk depends on the amount and duration of exposure.
At this time, officials have not reported any illnesses among students or staff connected to the campus.
District Preparing for Possible School Year Changes
School leaders said they are continuing to work closely with the Department of Toxic Substances Control, the City of Richmond, and the California Department of Education as the investigation moves forward.
The district plans to conduct additional environmental testing, implement any necessary mitigation measures, and develop contingency plans in case the campus cannot reopen before the school year begins.
Officials have not announced how long the testing process could take or whether students may need temporary alternative learning arrangements.
Families are expected to receive additional updates as environmental experts complete their assessments and determine the next steps for reopening the campus.
