The Le Roy Central School District has employed its own environmental and safety consulting firm in the case of mysterious physical tics found in a dozen students and suspected in six others. The firm, Leader, revealed its findings during a heated community meeting at Le Roy High School.

YNN's Sheba Clarke has more on what its representatives had to say about the school's environmental safety.

We want to know now what's going on, what are you going to do to protect my kids, what are you doing to protect these people's children," asked one parent at the meeting.

Fears and frustration have been some of the emotions of the Le Roy High School community and Superintendent Kim Cox wants that to change. Cox said the district hired the firm Leader to calm community fears and ensure their high school is environmentally safe for all students.

"All of the tests we've done, all of the medical testing, all of the professionals we have been working with for the past several months have concluded that there has been no environmental cause or infectious cause to the condition that we are seeing with our students. But it is clear to us that our community needs some re-assurance," said Le Roy Superintendent Kim Cox.

Over the past week, Leader representatives evaluated previous air quality and environmental testing done in December by the Genesee Valley Educational Partnership. On Saturday morning at a community meeting, they revealed GVEP's Indoor Air Quality Investigation Report, which proved there were no environmental dangers detected.

Still, they recommended more thorough and comprehensive tests need to be done.

"We reviewed the data. The test measures done in December were appropriate. They gave you a good indication there was no environmental factors emanating in this building. And as we looked at it, knowing the parents are concerned, we wanted to do a more deliberate, more comprehensive, more detailed sampling protocol," said Mary Ellen Holvey, Leader.

Within the next week or so, Leader representatives plan to collect air quality samples from all areas of the school building. The firm says it will set up monitors in select classrooms for 24 hour sampling after hours.

Industrial Hygienist Mary Ellen Holvey says they will be looking at things like carbon monoxide and dioxide levels, temperature and humidity. Also, classroom ventilation systems will be tested for volatile organic compounds, formaldehyde, and air fungi.

According to Leader's project manager, soil testing may also be done depending on their findings.

"We've got to look at the layout the building, the HVAC system and look at where people are and that's when we'll make a final decision and give further recommendations to the school board," said Peter von Schondorf, Leader.

Superintendent Cox says she did not know how much the district will be paying Leader for additional testing, but says she's confident in their work and believes it's necessary to the community.

"I think their services are necessary, so we can answer any questions that are still out there in people's minds and you can see there are still questions out there," said Kim.

The project manager says if all goes well, they should be able to get the results in about three weeks. He says they should be made available through the district.
