Over the last 10 years, the Clean Water State Revolving Fund (CWSRF)1
has invested over $12.5 billion in projects that include a variety of
innovative technologies to ensure clean water today and tomorrow.

1 Each state and Puerto Rico implements their CWSRF program in partnership with EPA.

2 EPA identified innovative technology investments via a keyword search of SRF-funded projects from 2013 to 2023, then grouped them into six technology types. The list of key
words used was compiled from EPA resources like the Searchable Clearinghouse of Wastewater Technology and the CWSRF database. The relative distribution of technologies
are presented on a logarithmic scale. Some SRF-funded projects might include more than one type of innovative technology.

CWSRF Emerging Contaminants funding first became available in fiscal year 2022, For
this first year of funding, programs across the country proposed nearly $50 million in
eligible projects to address emerging contaminants. Many projects will pilot innovative
technologies to address contaminants such as pharmaceuticals and personal care
products, microplastics, and per- and polyfluoroalky! substances (PFAS). New challenges
like emerging contaminants often utilize innovative technologies or apply well-established
technologies in new and innovative ways. For example, communities across the country
are investing CWSRF Emerging Contaminants funds into innovative removal and
destruction technologies that address PFAS. Eighty-five percent of the projects in this first
year of funding addressed PFAS.
