1 Guideline for interpretation of the results
0.0-0.2 µg/L Little to no risk from blue-green algal toxins. 0.2-1.0 µg/L Toxin detected but below the WHO drinking water guidelines: Low Risk 1.0 – 10 µg/L Toxin levels are above the drinking water guidelines but generally below the limits for recreational contact: Moderate Risk 10-20 µg/L Toxin levels are significant and approach the limit for recreational contact. High Risk >20 µg/L Toxin levels exceed the NYS guidelines for recreational contact. Users should avoid contact with the blooms.
