SAN DIEGO (CNS) - A 10,000-ton pile of contaminated dirt that mysteriously appeared last year beside the athletic fields at Southwest High School in Nestor came from a San Diego construction site and did not pose a health threat, the Sweetwater Union High School District announced Friday.
District spokeswoman Graciela Sevilla said the administration at Southwest High at the time had the dirt brought in from a construction site at 43rd Street and Logan Avenue, east of downtown San Diego. They wanted to build a berm alongside of the football field and place a "Raiders" sign on it in an effort to increase school spirit, she said.
Instead, the dirt had to be hauled off, which is costing the district close to $500,000.
"Everybody that was involved with the project is no longer working with the district," Sevilla told a local news station. "So it took us a while to do our own research (to learn how the dirt got there)."
The station reported last month that the dirt tested positive for lead and pesticides, but district officials said Friday the levels were so low that there was no health risk.
The work to get rid of the dirt, which is going to a landfill in Azusa in Los Angeles County, is expected to be finished Monday, according to the district.
