Comments

All samples collected on September 19th were analyzed for blue-green algal toxins using the protein phosphatase inhibition assay.

Blue-green algae were present throughout the entire bay.

Samples were collected during rain storms with high winds and no surface blooms were visible.

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

1 World Health Organization (WHO) guidelines for interpretation of the results. In cases where no toxin was detected, the possible risk category is reported based on the detection limit.
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.
