Comments:
All samples collected on June 10th were analyzed for blue-green algal toxins using the protein phosphatase inhibition assay.

Water quality was good with no visible blooms present.

Visual assessment via microscopy of the samples showed the presence of blue-green algae for all stations, albeit in very low abundance.

If you believe to have a Blue/Green Algae issue within a localized area near you in concentration please do the following:

Contact Cathy Comfort at our office 315.946.4136

• Provide her with your name, address, phone #, and an email address.
• Also, the site location in relation to a primary road and address if possible where you believe to have seen the algae.

 

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.
