E. coli or enterococci, which indicate fecal matter contaminating water, were detected at swim spots in New York state, Massachusetts, Michigan and elsewhere, authorities said.

Over 20 beaches in Massachusetts are closed on July 4 across the state, according to the Massachusetts Department of Public Health’s Interactive Beach Water Quality Dashboard. A total of 22 beaches are closed in towns such as Ashby, Beverly, Dartmouth and Salem.

The Massachusetts Alcoholic Beverages Control Commission Regulations state that Massachusetts residents can buy alcohol from liquor stores on the Fourth of July. Beer, wine, and liquor can also be purchased at open grocery stores. While there are no specific hour restrictions, people should check their local liquor store’s hours.
