About GreenWater Laboratories
Established in 2001, GreenWater Laboratories/CyanoLab is the only private full-service laboratory of its kind, with a strict focus on cyanobacteria and the toxins they produce. This allows our scientists to push the limits of cyanobacteria research and provide quality results.
Unlike other private companies, we do not make advancements proprietary, but rather share our observations and techniques in peer-reviewed research. We are scientists first, allowing both our business and non-business relationships to grow.
Our experts work closely with clients to provide technically advanced testing, analyses, monitoring and research - tailored to fit individual needs. Our company mission is to provide accurate and reliable data with the highest level of quality enabling our clients to make informed decisions.
