Suez New York will be treating Rockland’s water supply after levels of two chemical compounds were found to be above New York State’s new threshold for them. Suez says there is no health risk with the current water and it can continue to be used for all purposes. Levels of Perfluorooctane sulfonate and perfluorooctanoic acid registered below federal requirements but above new standards set by the state in August. Those compounds are commonly found in adhesives, non-stick surfaces, cosmetics and other items. In a statement from Suez, the Manager of the Rockland County Department of Health’s Water Supply Program, Dr. Daniel Miller, said he’s been working with the company to meet the new standards, and they should be able to install all the equipment necessary in less than three years.
