Recent Environmental Protection Agency tests reveal several areas of Island Trees High School in Levittown have lead contamination, a problem the school has been grappling with for years.

A letter sent to parents from the school board president states the EPA and New York State Department of Health ?have concurred that the data does not indicate that students or staff have been exposed to elevated levels of lead" because the areas tested were in remote locations.

Island Trees parent Brian Kelty says parents were assured there was no more lead dust in the building 19 months ago. The school used to have a rifle range that was closed in the 1980s. Two years ago the district completed a lead remediation project.

However, some parents argue not enough was done in light of the test results.

The district recently cleaned a storage room below the school?s stage that had tested higher than anywhere else in the school. During spring break and summer vacation the district plans to thoroughly clean the school and check its air system.
