How Healthy is Your Water?

With every changing tide, water flows from Buzzards Bay to Vineyard Sound and back again through Woods Hole, Robinson’s Hole, Quicks Hole, and Canapatsit Channel. This connection links the health – and futures – of Buzzards Bay and Vineyard Sound, which is why the Coalition began monitoring here in 2013. The health of Vineyard Sound is excellent, ranking as one of the healthiest waterways that we monitor.
