BlueGreen Water Technologies

BlueGreen Water Technologies was founded in Tel Aviv in 2014 by Eyal Harel and Dr. Moshe Harel. The privately held environmental technology company operates out of Israel with field operations spanning the US, South Africa, and China. Public details regarding exact valuations, funding amounts, and precise global headcount are limited. The company develops and deploys chemical treatments to eradicate toxic cyanobacterial blooms (blue-green algae) in large freshwater bodies and oceans.

The primary operational focus is treating harmful algal blooms using proprietary algaecide formulations. The core mechanism relies on a slow-release, floating application that localizes active ingredients in the upper water column where cyanobacteria concentrate. This approach specifically targets the biological collapse of the bloom while keeping the chemical concentration low enough to avoid harming the broader aquatic ecosystem. Beyond direct water remediation, BlueGreen generates revenue by quantifying the carbon sequestration achieved through ecosystem restoration, selling carbon offsets under its "Net Blue" program.

The flagship products are Lake Guard Blue (a copper-based formulation) and Lake Guard Oxy (a sodium carbonate peroxyhydrate formulation). Both products hold US Environmental Protection Agency (EPA) approval and are certified under the NSF/ANSI 60 standard for drinking water treatment. These formulations are dispersed from boats or drones directly onto lakes, reservoirs, and dams to trigger the programmed cell death of toxic algae.

The company's headquarters and R&D operations are located in Tel Aviv. While the technical development and executive management are based in Israel, the company's deployments are primarily international, involving contracts with local municipalities and national water authorities for large-scale interventions, such as the Roodeplaat Dam in South Africa and various state lakes in Florida and Ohio.
