EPA Update on PFAS Contamination of Pesticide Containers

In January 2021, EPA continued its testing which showed the PFAS were most likely formed from a chemical reaction during the container fluorination process which then leached into the pesticide product. After completing a robust quality assurance and quality control process, EPA can confirm that it has detected eight different PFAS from the fluorinated HDPE containers, with levels ranging from 20-50 parts per billion.  While EPA is early in its investigation, the agency will use all available regulatory and non-regulatory tools to determine the scope of this emerging issue and its potential impact on human health and the environment. It is important to note that although these types of products should not be a source of PFAS, the data indicates that the amount of PFAS that has entered the environment from the contamination in the containers the agency tested is extremely small. The agency is also committed to coordinating with the affected entities involved and their supply and distribution chains, pesticide users, the pesticide and packaging industry, and its federal, state, and tribal partners as it works through this complex health and environmental issue.
