How It Works
- Great Pond Foundation scientific staff collect & analyze environmental and cyanobacteria data weekly
- Data and analyses are sent to Island Boards of Health for review
- Island Boards of Health use Massachusetts and EPA recreational limits and issue public health recommendations
- MV CYANO releases coordinated color-coded maps indicating the cyanobacteria bloom risk level and associated recommendations as seen on the right –>
- Signage will also be posted along pond shores if YELLOW, ORANGE, or RED risk levels are present.
