The New York State Department of Health is leading the investigation into the cause of the outbreak, with assistance from the county department of health. A water sample taken this summer tested positive for the Legionella bacteria. Subsequent tests in August and September came back negative.
The facility has since hired a remediation company to help prevent the spread of the disease.
