SciDev Ltd (ASX: SDV) (' SciDev ' or 'the Company ') has secured a contract with US consulting firm Halff for the treatment of PFAS-impacted investigation derived waste on US Department of Defense (DoD) sites. This is SciDev’s first contract in the US for PFAS remediation.

Under the A$396K contract, SciDev will treat up to 190,000 litres of PFAS contaminated water across four DoD installation in the southern United States.

PFAS contamination on DoD sites remains a critical issue, with legacy firefighting foams polluting groundwater near military bases. The DoD has identified elevated PFAS contamination across 80% of US military bases

SciDev CEO Seán Halpin said , "I am thrilled our first contract in the United States for PFAS treatment is supporting the US Department of Defense. Assisting the DoD with their PFAS concerns is a strong validation of our world-leading remediation technology and highlights the growing global demand for sustainable, effective water treatment solutions.

“The partnership with Halff represents a significant commercial opportunity as we continue to scale our presence in the US, allowing us to take advantage of the broader national market for PFAS remediation currently valued at USD$220 billion.
