Cyanobacteria - formerly called blue-green algae - are likely responsible for turning your ponds green, blue-green or brownish green. While the discoloration might seem harmless, the real concern lies in the toxins they produce, known as cyanotoxins.
Human and animal exposure to these toxins, primarily through ingestion, inhalation or skin contact, can lead to symptoms like skin irritation, gastrointestinal distress, and even liver or neurological damage.
That’s why our scientists at GreenWater Laboratories have made cyanobacteria the sole focus of our research, testing, analyses and monitoring. The only private full-service laboratory of its kind, our experts push the limits of cyanobacteria research to provide quality results. Our scientists work closely with clients to provide technically advanced testing methods tailored to fit their needs. This enables our clients to make the most informed decisions possible.
