LAS VEGAS (FOX5) -

Walter Johnson Junior High School is set to resume classes Tuesday after a mercury contamination forced students and staff out for three school days.

Clark County School District informed parents Monday of the reopening. In addition, a CCSD news conference was set for 4:30 p.m. to address the reopening.

Students were kept out of their classrooms for a third straight school day Monday as decontamination crews continued combing the campus for mercury.

According to the Environmental Protection Agency, 80 bags belonging to students were brought in for testing over the weekend. Of those bags, 16 bags were being retested. In addition, 60 homes where those students reside were evaluated, and one family was asked to temporarily evacuate. 

By Monday morning, the EPA cleared all parts of the school except the gym, which was expected to be cleared by the afternoon.

"It is unclear where it was actually found because it was so high, so we can't pinpoint that. So, we're going to do another investigation," said Randy Nattis, of the EPA, in reference to the evacuated home. 

The EPA also inspected Kristina Langendorf's home, but she said it was cleared. 

"It was scary because I didn't know what to expect or what they were going to find," said Langendorf. 

Mike Barton, of the Clark County School District, said it remains unclear who brought the mercury to the school.  

"We do believe it was brought in potentially by a student. We don't know yet, but it's under investigation by our school police," said Barton.

Nattis said crews recovered nearly a quarter of a cup of mercury, which he described as a "significant amount."

According to the EPA, about 0.61 grams of mercury can be found in a baby thermometer.

The district said the Environmental Protection Agency will continue to clean the school Monday.

The school district said parents were updated on ParentLink on classes for Tuesday.
