374Water Inc (NASDAQ:SCWO) announced that the City of Cedar Rapids, Iowa, has partnered with the company on a project aimed at destroying per- and polyfluoroalkyl substances (PFAS) in municipal biosolids.
The project will be carried out in partnership with the Cedar Rapids Water Control Pollution Facility (CRWPCF) and engineering consultancy Brown and Caldwell.
The work will evaluate 374Water’s AirSCWO system as a potential replacement for multiple existing treatment processes at the Cedar Rapids facility, the company said.
According to the company, the project is expected to begin in early 2026. The initial phase will involve destruction of biosolids generated at CRWPCF, followed by validation of the results by an independent third-party laboratory.
The findings from the evaluation are expected to be delivered to Brown and Caldwell and the city facility by the end of the first quarter or early in the second quarter of 2026.
PFAS are a group of man-made chemicals that persist in the environment and can accumulate in water, soil, and wastewater systems. 374Water said the City of Cedar Rapids is assessing technologies capable of fully destroying PFAS-contaminated waste streams, including biosolids, as part of efforts to address regulatory requirements and public health considerations.
“374Water is an ideal partner to enable meaningful action against PFAS contamination at the City of Cedar Rapids’ advanced wastewater treatment facility,” said Stephen Jones, 374 Water chairman, interim president and CEO in a statement.
"Our AirSCWO technology has demonstrated the effectiveness, scalability, and versatility of our solutions to destroy solid and liquid wastes.”
