School Removes Hazardous Waste

Ten tons of oil-contaminated earth and four tanks of fuel and oil were removed last month from the Monrovia High School campus and the neighboring school district maintenance yard.

The project was prompted by state laws that require agencies holding hazardous substances in underground storage tanks to meet tighter monitoring standards, said Nitra Hall, assistant superintendent of business services for the Monrovia Unified School District.

A six-foot-tall, three-foot-wide tank leaked, causing the extensive contamination, Hall said. The concrete tank contained waste oil dumped from the school’s auto shop over 24 years.

An unused 3,000-gallon boiler fuel tank also was unearthed on the campus, she said.


Two 2,000-gallon diesel and gasoline tanks used for fueling district vehicles were removed from the maintenance yard.
