ORANGE COUNTY, Fla. -- Army engineers took soil samples Tuesday from a Central Florida middle school near where some World War II-era bombs and munitions are believed to be buried underground.

Odyssey Middle School in Orange County, Fla., was constructed near property that used to be owned by the military, which used it as a practice range.

Recently, in an area located about 1,500 feet from the school on private property, an owner found four bombs and other munitions.

Local 6 News reported that there were metal pieces of small firearms, high-explosive bombs and air-to-ground rockets, and more unknown pieces are likely in a nearby area.

Workers then took soil samples from the area and discovered the soil contained nitroglycerine -- which is a compound commonly found inside explosives.

Representatives from the U.S. Army Corp. of Engineers were testing the soil Tuesday for contamination.

On Thursday, engineers will do a sweep of the school to determine if there are any dangerous munitions on campus.

A fence will also be constructed to keep the school area separate from the area where the bombs were located.

Odyssey Middle School opens to students in about two weeks.
