30 MA Beaches Closed Ahead Of Sizzling July 4 Weekend

SALEM, MA — Thirty Massachusetts beaches — including three in Salem — were off limits to
swimming ahead of the July 4 holiday weekend because of water contamination.

Children's Island Back and Willow Avenue in Salem were among those closed. Most of the 30 beaches were closed 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. Walden Pond in Concord is closed for the season because of safety concerns associated with the construction of a new bathhouse.

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 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.
