The water quality at beaches in Massachusetts must be monitored because data helps local health officials determine when to close a beach due to unsafe conditions and notify the public, so beach visitors can make informed decisions about swimming.

Swimming in unsafe waters can result in gastrointestinal and respiratory health issues.

The state conducts water quality testing from Memorial Day through Labor Day.
