Our goal is to prevent further contamination of lands, waters, air, and biota by highly toxic compounds known as PFAS. 

The PFAS Team is a national team of the Sierra Club that works with the Grassroots Network.  Our team is interdisciplinary and includes scientists, policy experts, and activists. 

This site supports work by Sierra Club chapters and communities.

In 2024 we focus on

• Community science projects to test for PFAS in rivers and streams and in sludge/biosolids from wastewater treatment plans and
• Web resources and support for community efforts to stop the spread of PFAS in sludge/biosolids onto lands and farms and into commercial garden products.
