Empowering Communities to Protect Water Systems & Public Health
A project of the Pollution Prevention Resource Center, Western States Alliance (WSA) works to help professionals identify and implement best management practices for both Fats, Oils, and Greases (FOG) and emerging contaminants. We are a membership organization comprised of environmental professionals from across the United States. Learn more about our team here.
Our mission is to provide comprehensive knowledge and technical assistance that advances technologies and best management practices, conserves resources, maximizes the value of FOG, and prevents harmful effects on wastewater systems and public health.
How We Can Help

Conferences & Workshops
We offer two technical training conferences each year: The FOG Forum & the Pacific Northwest Pretreatment Workshop. Both events offer immersive training, program development and implementation sessions, and abundant opportunities for networking with fellow environmental professionals.

Technical Trainings
With funding from the USDA and EPA, we provide both virtual and in-person trainings to help small rural communities and those who serve them. The trainings focus on FOG abatement, building the business case for your program, program implementation, and emerging chemicals of concern.

Technical Resource Library
Our resource library is a “one-stop” shop for learning about emerging contaminants (PFAS, phtalates, pesticides, and beyond), as well as FOG, its value as a resource, its contribution to sanitary sewer overflows, and actionable insights for establishing or enhancing a FOG abatement program.
