MV CYANO

MV CYANO is a collaborative initiative among Island Boards of Health and scientists from Great Pond Foundation to monitor cyanobacteria on Martha’s Vineyard. 
Cyanobacteria, a.k.a. blue-green algae, are a group of microorganisms found in all Vineyard waters. When cyanobacteria grow rapidly or bloom, they can produce cyanotoxins, which when concentrated, can cause adverse health effects in humans, pets, or livestock who wade in or ingest blooming waters.

HOW IT WORKS

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