Nevertheless, almost 50 beaches are closed this weekend due to unsafe bathing water.

The Massachusetts Department of Public Health (MDPH) states that swimming in the water at these closed beaches poses a risk of illness due to the high concentration of bacteria. Symptoms can range from nausea and vomiting to sore throat and fever.
