Comments:

All samples collected on July 19th were analyzed for blue-green algal toxins using the protein phosphatase inhibition assay. Water quality was good.

Traces of blue-green algae were present but no visible blooms were observed. Please beware that blooms may initiate in marinas or coves where floating weeds have accumulated.

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.
