All samples collected on July 25th 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 and there appeared to be a decomposing bloom in Oak Park Marina.
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.
