Removing PFAS compounds from drinking water currently relies heavily on Granular Activated Carbon (GAC) filtration. SCWA spends approximately $90,000 for each carbon change-out in a GAC vessel.
This inaugural grant funds a pilot program to develop a new, highly effective carbon source manufactured from local waste products, including kelp, oyster shells, wood chips, and invasive bamboo.
target The Goal
By engineering a locally sourced biochar capable of targeting multiple PFAS compounds simultaneously, SCWA seeks to drastically reduce the cost of filter materials while establishing a sustainable, closed-loop supply chain right here on Long Island.
update Project Scope
The $220,000 Phase 1 budget (co-funded with Suffolk County) includes procurement, installation, initial operation, and performance validation of the biochar materials.
"Testing materials like kelp and oyster shells keeps SCWA ahead of the curve in water treatment innovation. A successful pilot could reduce our carbon change-out costs and maintain our high water quality standards."
