About The Webinar
![]()
Harmful algal blooms (HABs) are an increasing challenge for drinking water reservoirs, wastewater lagoons, industrial cooling ponds, and recreational lakes. These events can affect water quality, increase treatment pressure, create taste and odor problems, and disrupt normal operations. This webinar series on harmful algal blooms explores practical approaches to managing bloom-forming cyanobacteria in managed water systems.
Across four sessions, participants will learn about the environmental drivers of algae blooms and how ultrasonic technology can help suppress cyanobacterial dominance and stabilize water quality without chemical treatment. Each webinar includes real-world insights on bloom dynamics, system deployment considerations, and operational outcomes in reservoirs, lagoons, and other surface waters.
Who Should Attend the Harmful Algal Bloom Webinar?

Join and reserve seats for our harmful algal bloom webinar series on managing blooms in reservoirs, wastewater, and industrial water systems.
Webinar 1: Ultrasonic Algae Control Fundamentals
Date: 31st March 2026
Time: 16:30 CEST | 10:30 AM EDT | 07:30 AM PDT
Speakers: Dr. E.J. Neafsey & Ally Berry
This session introduces the biological fundamentals of algae and cyanobacteria, focusing on bloom-forming species commonly encountered in reservoirs, lagoons, and engineered water systems. Participants will review the environmental conditions that drive bloom development, including nutrient loading, thermal stratification, light availability, and hydrologic stability. The session also explains how ultrasonic frequencies interact with gas vesicles inside cyanobacteria, disrupting buoyancy regulation and reducing bloom dominance. Deployment considerations such as basin geometry, power distribution, frequency programming, and integration with broader water management strategies will also be discussed.
Webinar 2: Protecting Drinking Water Reservoirs from Harmful Algal Blooms
Date: 19th May 2026
Time: 16:30 CEST | 10:30 AM EDT | 07:30 AM PDT
Speakers: Dr. E.J. Neafsey & Mr. Steve Palmer from Donner Summit Public Utility District
This webinar focuses on bloom management in drinking water reservoirs and source-water systems. Topics include cyanotoxin risks, taste and odor compounds such as geosmin and MIB, seasonal bloom dynamics, and strategies for maintaining stable raw water conditions during bloom-prone periods. Participants will explore how ultrasonic technology can support proactive source water protection while complementing existing monitoring and treatment programs.
Webinar 3: Managing Harmful Algal Blooms in Recreational Lakes and Reservoirs
Date: 21st July 2026
Time: 16:30 CEST | 10:30 AM EDT | 07:30 AM PDT
Speakers: Dr. E.J. Neafsey & Ally Berry
Harmful algal blooms increasingly threaten the safety and ecological balance of lakes and reservoirs used for swimming, boating, and fisheries. This webinar reviews the environmental conditions behind bloom formation and explores how ultrasonic technology can suppress cyanobacterial dominance without chemical treatment. Integrated management approaches, including monitoring and watershed nutrient management, will also be discussed.
Webinar 4: Managing Algal Growth in Wastewater, Industrial, and Reuse Systems
Date: TBA
Time: TBA
Speakers: TBA
Algal blooms in wastewater lagoons, reuse reservoirs, and cooling ponds can contribute to elevated suspended solids, pH fluctuations, dissolved oxygen cycling, and operational challenges. This harmful algal bloom webinar examines how ultrasonic algae control can help stabilize water quality in high-nutrient systems and support reliable operations in industrial and treatment environments. Design considerations for lagoons, lined basins, and large industrial reservoirs will also be discussed.
