BioLargo CEO Dennis Calvert to Present Global Environmental Leadership Award to Robert Bilott at Nassau County PFAS Forum

BioLargo sponsors legal and technical forum on PFAS contamination; company 's PFAS remediation technology to be featured on a technical panel alongside leading environmental engineering firms, followed by a special screening of the film "Revealed: How to Poison a Planet. "

WESTMINSTER, CA / ACCESS Newswire / April 1, 2026 /BioLargo, Inc. (OTCQX:BLGO), a cleantech and life sciences innovator, today announced that CEO Dennis P. Calvert and Tonya Chandler, President of BioLargo Equipment Solutions and Technologies (BEST), will participate in a PFAS legal and technical forum hosted by the Nassau Academy of Law at the Nassau County Bar Association on April 29, 2026 in Mineola, New York.

Calvert and Chandler will present the Global Environmental Leadership Award, sponsored by the 22nd Century by Design Fund, to Robert Bilott, Esq., the environmental attorney whose two-decade legal battle against PFAS manufacturers was the subject of the 2019 film Dark Waters. Bilott, a partner at Taft, Stettinius & Hollister LLP, will also deliver the forum 's keynote address.

Chandler will participate on the forum 's technical panel alongside representatives from Roux Associates, D & B Engineers and Architects, and GZA GeoEnvironmental. The panel will address the scale and urgency of PFAS contamination, gaps in current remediation approaches, and the regulatory landscape driving demand for next-generation treatment technologies. BioLargo 's AEC (Aqueous Electrostatic Concentrator) technology, which removes PFAS from water without generating secondary waste streams, is among the emerging solutions designed to address limitations of conventional treatment methods.

BioLargo is a sponsor of the event, which is expected to convene attorneys, regulators, engineers, and environmental scientists working on PFAS challenges across New York and the Northeast.

"Robert Bilott 's work helped bring PFAS contamination into public awareness at a time when very few people understood the scope of the problem. Today, with EPA enforcement timelines accelerating and thousands of water systems facing mandatory compliance, the question has shifted from whether PFAS will be addressed to how quickly effective solutions can be deployed. That 's a question BioLargo is built to answer, " Commented Calvert.

Tonya Chandler added, "The PFAS treatment challenge is not just about removing contaminants from water. It 's about doing so at a cost and scale that makes compliance achievable for municipalities and water utilities nationwide. That 's the gap we 're focused on closing. "
