8/20/22: Town Beach Water Quality remains good

PUBLIC HEALTH ADVISORY

AUGUST 20, 2022

On August 19, 2022 the Board of Health received results of a water quality sample collected on August 9, 2022 at the Town Beach. The results indicate no harmful levels of cyanobacteria (blue-green algae).  

At this time, all Normal activities are permitted, because:

• Cyanobacteria levels are < 70,000 cells/milliliter (c/mL)
• Water visibility is greater than 4 feet (on Aug 16, 2022, ~63 inches).

The Town Beach water quality monitoring sign (the Dial sign) stays at Green - all activities allowed.

What happens next:

The Board of Health will continue to test the water quality every other week.  If the cyanobacteria cell counts exceed 70,000 c/mL or water visibility drops below 4 feet, the Board will evaluate issuing a No Swimming Advisory.
