As part of the U.S. Environmental Protection Agency’s extensive efforts to address PFAS, the agency announced it is making new information available about EPA testing that shows PFAS contamination from fluorinated containers.
Through a coordinated effort with both the Commonwealth of Massachusetts and a pesticide manufacturer, the agency has determined that fluorinated high-density polyethylene (HDPE) containers that are used to store and transport a mosquito control pesticide product contain PFAS compounds that are leaching into the pesticide product.
While the agency is early in its investigation and assessment of potential impacts on health or the environment, the affected pesticide manufacturer has voluntarily stopped shipment of any products in fluorinated HDPE containers and is conducting its own testing to confirm EPA results and product stability in un-fluorinated containers. In addition, EPA has issued a request for information under the Toxics Substance Control Act (TSCA) to the company that fluorinates the containers used by certain pesticide manufacturers. The TSCA subpoena requests information about the fluorination process used to treat the containers.
