Nahant Beach (South Site) is sampled from June 1st to September 14th

SOURCE INFORMATION

Local boards of health and the Massachusetts Department of Conservation and Recreation conduct the vast majority of beach water sampling in Massachusetts. Most marine beach samples collected at public beaches are analyzed at Massachusetts Department of Public Health (MDPH) contracted laboratories. Under the beaches acts, MDPH is responsible for ensuring the regulations are adhered to by beach operators and local boards of health and providing technical assistance where needed.

In the Nahant region water is tested on a weekly basis. The testing frequency depends on how likely the beach is to have water quality issues. Infrequently used beaches or beaches that historically have had very few, if any, water quality issues are tested less often, while high-use or historically problematic beaches are tested more often. Detailed information on testing frequency is made available in the information listed for a particular beach.

The water is tested for Enterococci to determine water quality in brackish and marine water environments. Enterococci is a group of bacterial species typically found in human and animal intestines and are therefore present in sewage. Enterococci is also referred to as indicator organisms. Indicator organisms are used to predict the presence of pathogenic, or disease-causing, organisms associated with fecal contamination.

Swim Guide checks for the latest information daily, Monday - Friday during the swimming season.

A beach is marked Green when less than 104 units of Enterococci / 100 ml of water is present in a single sample, or when the geometric mean of 5 samples contains less than 35 units / 100ml of water.

A beach is marked Red when more than 104 units of Enterococci / 100 ml of water is present in a single sample, or when the geometric mean of 5 samples contains more than 35 units / 100ml of water.

A beach is marked Grey when there is no current or reliable monitoring information available.
