Mass. beach closures: Over 50 beaches are closed on Monday, Aug. 25

Several dozen beaches across Massachusetts are closed off to the public on Monday following a weekend that saw warming temperatures.

On Monday, 54 beaches were closed mostly due to high levels of bacteria present in the water, according to the Massachusetts Department of Public Health (DPH). Bacteria levels can rise due to the presence of agricultural runoff, storm/rainwater runoff, excess sewage and wildlife or animal waste.

Other closures were due to cyanobacteria blooms, DPH stated. These blooms result when algae release toxins into the water that are harmful to people and animals.

Finally, Walden Pond State Reservation's beach is closed to allow for ongoing work on a new, state-of-the-art $6.1 million bathhouse that will last all of summer 2025. Red Cross Beach at Walden Pond will remain open with no lifeguards.

What are the risks?

Swimming in beach water that has high levels of bacteria can be risky and can result in illnesses, including:

• Gastrointestinal symptoms- nausea, vomiting, diarrhea and abdominal pain

• Respiratory symptoms- sore throat, cough, runny nose and sneezing

• Dermatological symptoms- skin rash and itching

• Eye and ear symptoms- irritation, earache, itching

• Flu-like symptoms- fever and chills

Stay aware of any warnings or beach closures that indicate that the water is not safe. Check the weather forecast, avoid swimming after heavy rain, watch for signs of water pollution like discolored, fast flowing and strong smelling water, do not swim near trash or litter floating in the water, avoid swallowing the water and swim in areas designated as "swim beaches."

Although a beach could be posted, the public can still visit the location and take part in other activities that do not involve contact with the water. This can include anything from playing sports like volleyball or frisbee to sunbathing or collecting seashells or sea glass, DPH stated.

The public can also help to reduce contamination and pollution at the beach by:

• Cleaning up after pets

• Not feeding the birds as it encourages them to hang around the beaches, which increases fecal matter

• Using public restrooms

• Picking up and throwing away trash using public restrooms or properly disposing of it at home

• Not entering the water when sick or feeling unwell

• Changing diapers and putting plastic or rubber pants, known as swim diapers, on diapered children before they enter the water

• Not dumping anything down storm drains, as water moving through these drains does not get treated at a wastewater facility and flows directly into lakes and streams

• Avoiding the use of fertilizers and pesticides in yards since these chemicals can easily carry into the surface of waters during rain events and snowmelt

• Use walkways and avoid walking on dunes to prevent erosion and preserve vegetation that filters out pollutants from runoff before they reach the beach
