Arizona Tribune - BioLargo Equipment Solutions & Technologies' "PFAS Lady" to Teach PFAS 101 at 41st Annual Tri-State Seminar

WESTMINSTER, CA / ACCESS Newswire / July 29, 2026 / BioLargo, Inc. (OTCQX:BLGO), a cleantech and life sciences innovator that creates and commercializes sustainable technologies to solve tough environmental challenges, announced that Tonya Chandler, will lead a workshop titled "PFAS 101 - Everything You Didn't Want to Know About PFAS" at the 41st Annual Tri-State Seminar on Monday, August 3, 2026, from 7:30 a.m. to 4:00 p.m. at the South Point Hotel & Casino in Las Vegas, Nevada.

Chandler, President of BioLargo Equipment Solutions & Technologies, Inc. (BEST), BioLargo's water treatment equipment subsidiary, will teach the course for the fourth consecutive year.

With a mission to "empower water professionals" through education, last year's Tri-State Seminar drew nearly 4,800 participants from five countries and 41 U.S. states. "With hundreds of speakers featured during Tri-State's popular sessions, it's not often we invite a speaker back four years in a row," said Lisa Culbert, Chair for this year's 41st Annual Tri-State Seminar in Las Vegas. "Tonya's grasp of complex PFAS details and her humor and ability to connect with participants are the reasons we keep inviting her back. Attendees love her workshop," Culbert continued.

"It is our honor to be part of such a great event, and we are thankful that Tri-State trusts us to deliver knowledge and share the lessons we have learned from front-line experience," said Tonya Chandler, President of BioLargo Equipment Solutions & Technologies. "But what matters most to me is being able to invest quality time with industry leaders, technology specifiers, engineers, and utility operators who are making decisions about where PFAS precious treatment dollars will be put to work in the future. Our extensive experience in PFAS collection, destruction and disposal has taught us many lessons that we believe can save everyone time and money and help get the job done.

Chandler's continued invitation to teach at Tri-State reflects the standing BioLargo's PFAS treatment expertise has built among the engineers, regulators, and utility operators who write the specifications for water treatment projects nationwide. PFAS 101 is designed to give attendees a practical, plain-language grounding in PFAS chemistry, health effects, regulatory drivers, and treatment options, taught from the perspective of a company actively deploying PFAS removal technology in the field.
