Why are so many beaches in Massachusetts closed?
Most of the beaches on the list are closed due to excessive bacteria in the water. Recent rainfall can bring pollution or sewage into the water, causing bacteria levels to go up.
Swimming in water with high bacteria levels can cause illness, health experts warn.
Longnook Beach in Truro has been closed so far this summer due to erosion, and the beach at Walden Pond is underwater because of heavy rain last year.
And on Nantucket, six south shore beaches are closed to swimming because of debris from a broken wind turbine blade that washed ashore.
