About GreenWater Labs

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 us 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, which has allowed both our business and non-business relationships to grow.

Our experts work closely with our clients to provide technically advanced testing, analyses, monitoring and research – tailored to fit each of their individual needs. Our company mission is to provide accurate and reliable data with the highest level of quality so that our clients can make informed decisions.
