BETHPAGE - The New York State Department of Health has rejected Nassau County's request to continue studying underground toxins in Bethpage.

As News 12 Long Island has reported, contaminates were found in the groundwater below Bethpage Community Park. The state has analyzed decades of cancer cases near the old Grumman site to see if the two were connected.

In a statement released today, the department said that it has determined that further study would not provide conclusive answers to the community's questions.

The county maintains that the study was too small. Nassau County Executive Ed Mangano says he plans to appeal the decision.
