City of San Diego officials are scheduled to test the water at Birney Elementary School in University Heights on Friday to determine if repairs successfully cleared contaminants from the plumbing system. Birney is one of two San Diego Unified School District campuses where elevated levels of lead were discovered in the water. Officials with the city’s Public Utilities Department told the City Council’s Environment Committee that while the city is testing for contaminants, school districts are responsible for making repairs.
