All samples collected on May 31st were analyzed for blue-green algal toxins using the protein phosphatase inhibition assay. Traces of blue-green algae were present from North to South on the East side of the bay.

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.
