"So the results of the study identified four compounds, polychlorinated biphenyls and three pesticides chlordane, heptachlor, and heptachlor epoxide," Komorek said. "Those three compounds are known or are probable carcinogens."
She said the findings showed levels of potentially cancer-causing compounds exceeding EPA standards.
Earlier this year, Colonia High School gained national attention after more than 100 former students and faculty reported online that they were diagnosed with brain tumors over three decades.
About half were cancerous.

"It was shock, I said what is the likelihood that a husband and wife can both have an acoustic neuroma? And what is the likelihood that a sister of me and my wife can have a brain tumor at the same time," said Al Lupiano.
Officials investigated and said they found no significant radiation in the building.
"Everybody concluded that there was no need for further testing and that the grounds and the buildings were 100% safe," said Mayor McCormac.
But Komorek was not convinced.
"I think that air testing should be done immediately to determine whether or not there are hazardous levels of those chemicals in the indoor air," she said.

She was so concerned by what she found that she transferred her daughters out of the school.
The school district says it has sent her results to state health and environmental agencies.
