2 Salem Beaches Among 16 Closed To Swimming Across MA

SALEM, MA — Two Salem beaches were among 16 across the state closed to swimming because of bacterial contamination as temperatures soared into the 90s late this week

Most of the beaches that close across Massachusetts each summer do so because of high bacteria levels caused by storm runoff and other means of fecal contamination. Water quality at public beaches in Massachusetts is required to be monitored by local public health departments.

When the water quality is unsafe, the beach must be "posted" with a sign indicating that swimming is unsafe and may cause illness.

Massachusetts beaches closed as of 2 p.m. on Friday include:

• Ashby Damon Pond
• Brewster Cliff Pond at DYS
• Brewster Cliff Pond at Main
• Concord Walden Pond East
• Concord Walden Pond West
• Natick Cochicuate State Park
• Plymouth College Pond Day
• Plymouth Fearings Pond Beach 1
• Plymouth Fearings Pond Beach 2
• Revere Beach Beach Street
• Revere Beach Carey Circle
• Revere Beach Oak Island Street
• Revere Beach State Police Barracks
• Salem Forest River Point
• Salem Juniper Point
• Shutesbury Lake Wyola

The bacteria used as indicator organisms to test the waters at beaches are Enterococci and E. coli. Marine beaches are tested for the presence of Enterococci. Freshwater beaches are tested either for the presence of E. coli or Enterococci. Enteric bacteria are indicator organisms found in the intestines of warm-blooded animals and humans, often associated with fecal contamination.

An elevated presence of these organisms indicates the water may not be safe for human or animal consumption or contact, and may cause symptoms ranging from gastrointestinal pain to eye and ear discomfort to flu-like symptoms.

Most of these symptoms are minor, but occasionally a more serious illness may occur. Children, the elderly, and those with weakened immune systems are at greater risk of developing serious symptoms.

Some beach areas may remain open for recreational activities, though any contact with the water is strongly discouraged.
