Understanding PFAS and Your Home Garden

There are many ways individuals can be exposed to PFAS, including their clothing, what they cook with, their water, personal care products, and materials in their homes. Your garden may be one potential source of PFAS exposure.

There are a number of routes that PFAS may have entered your garden as outlined on this page. If none of these apply to your garden, you are likely at low risk for PFAS being present in your garden. 

The purpose of this document is to help you investigate the likelihood of elevated levels of PFAS in your garden.
