BioLargo, Inc a clean water technology company has launched a new service testing customer water to detect per- and polyfluoroalkyl substances (PFAS) contamination levels.
The new service will also advise and administer treatment equipment options to meet federal, state and local regulatory requirements.
The program is described as offering peace of mind and proof of concept to customers who need PFAS water treatment solutions in the face of an uncertain and rapidly evolving technological and regulatory landscape.

According to the Environmental Protection Agency, PFAS are man-made chemicals that have been in use in the US since the 1940s. Of the PFAS group, PFOA and PFOS have been the most extensively produced and studied.
“Both chemicals are very persistent in the environment and in the human body – meaning they don’t break down and they can accumulate over time. There is evidence that exposure to PFAS can lead to adverse human health effects,” the US agency’s website states.
As the Federal government and many states begin tightening regulations due to mounting evidence on the impact of PFAS chemicals on human health, BioLargo's new PFAS testing program aims to help customers identify and address PFAS contamination in water.
Once contamination and water chemistry are characterized, BioLargo selects appropriate water treatment equipment from a selection of different technologies that addresses the customer's specific water chemistry and PFAS contamination makeup.
From there, BioLargo’s proprietary PFAS water treatment technology, the Aqueous Electrostatic Concentrator (AEC) is deployed.
"With the launch of this new program, our engineers will be able to better serve municipalities that are struggling with having to close water wells due to PFAS contamination,” Randall Moore, President of BioLargo's engineering division said in a statement.
“Our AEC system reduces treatment costs because it generates only a fraction of the PFAS-laden waste compared to other treatment technologies like carbon filtration or ion exchange,” he added. “No two water sources have the same underlying chemistry, and there are over 4,500 different PFAS compounds that can contaminate water. Thus, it is crucial to optimize treatment processes for each situation."
