Comments

All samples collected on July 12th were analyzed for blue-green algal toxins using the protein phosphatase inhibition assay. Water quality was good. Blue-green algae were present via microscopy, albeit in low abundance and no visible bloom was observed out on the Bay.

These samples showed minimal risk for microcystin toxins. Users are still encouraged to avoid contact with visible blooms as other irritants may be present.

0.0-0.2 μg/L Little to no risk from blue-green algal toxins: Minimal risk.
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 WHO drinking water guidelines
but generally below the limits for recreational contact: Moderate risk
10-20 μg/L Toxin levels are significant and approach the
WHO limit for recreational contact: Higher risk
>20 μg/L Toxin levels exceed the WHO guidelines for recreational contact: Highest risk.
Users should avoid contact with the blooms.
