A testing laboratory for harmful algae
Cyanobacteria—often called blue-green algae—are likely behind the green, blue-green, or brown tint in your water. But the real danger isn’t the color—it’s the cyanotoxins they release, which can cause illness and even liver or neurological damage in humans and animals.
At GreenWater Laboratories, cyanobacteria are our sole focus. As the only private full-service lab dedicated to their study, we deliver cutting-edge testing and expert analysis to help clients make informed, confident decisions.
