In 2018 the New York State Department of Health adopted one of the strictest maximum contaminant levels (MCL) in the nation for 1,4-dioxane. 1,4-dioxane was used as a solvent and a chlorinated solvent stabilizer for industrial chemicals. The chemical can enter the water through unintended chemical spills, leaks or wrongful disposal practices. Products that contain the chemical include laundry detergent, soap, shampoo, and body wash. Once in the groundwater and soil, the physical and chemical properties of 1,4-dioxane make it not only persistent, but very difficult to remove. Advanced Oxidation Process (AOP) is the most effective method to remove 1,4-dioxane from groundwater resources. The Carle Place Water District has initiated the addition of AOP treatment at Well No. 5 which is located at the entrance of Fuschillo Park.
With the adoption of the NYS DOH regulation to establish a maximum contaminant level (MCL)for 1,4-dioxane of 1.0 parts per billion, it is necessary that the District construct suitable treatment for the removal of the contaminant by the Summer of 2022. Without treatment at Well no. 5, the District’s system capacity will be significantly reduced. As such, the Board of Commissioners have declared an emergency resolution for the rapid deployment of an interim treatment system at Well No. 5 to ensure that drinking water continues to meet all current regulations and fire flow protection can be satisfied. The entire treatment will be constructed on the District’s Well No. 5 property.
The Carle Place Water District understands the need to maintain the appearance of the Park and our properties. Upon completion of construction fencing and screening will be installed.
