Massachusetts Beaches Temporarily Closed to Swimming

MA Beaches Confront Closures Due to Bacterial Contamination and Algal Blooms

Breaking News: Several popular swimming destinations across Massachusetts are currently off-limits to the public due to significant water quality concerns. Beaches in Salem, Springfield, Swampscott, Templeton, Townsend, Upton, Winchendon, and Winthrop have issued closures, primarily citing “Bacterial Exceedance” and “Harmful Cyanobacteria Bloom” as the reasons.

The widespread bacterial contamination is frequently attributed to the cumulative impact of runoff pollution and sewage overflows, particularly following recent heavy rainfall events. This situation mirrors closures experienced by numerous beaches just last weekend after torrential downpours swept through the region.In a separate, but equally concerning, development, certain swimming spots are facing closures due to harmful cyanobacteria blooms, commonly known as blue-green algae. The Centers for Disease Control (CDC) explains that these blooms thrive in warm, slow-moving water bodies enriched with nutrients such as nitrogen and phosphorus.

Evergreen Insights:

The recurrent closures of swimming areas due to bacterial exceedance serve as a stark reminder of the direct link between urban and agricultural runoff and public health. Heavy rainfall exacerbates this issue by washing pollutants from surfaces – including streets, farms, and septic systems – into our waterways. This highlights the ongoing need for robust stormwater management strategies and public education on minimizing pollution at its source.

Similarly, the prevalence of harmful cyanobacteria blooms underscores the impact of nutrient pollution on aquatic ecosystems. Excess nutrients, often from fertilizers and wastewater, fuel the growth of these algae, which can produce toxins harmful to humans and animals. Addressing nutrient loading through improved wastewater treatment, agricultural best practices, and responsible lawn care is crucial for maintaining healthy water bodies and recreational opportunities year-round.

Swimming in waters contaminated with elevated bacteria levels or exposed to cyanotoxins can lead to a range of health problems, including gastrointestinal and respiratory illnesses, as well as skin irritations like rashes and itching. As such, adherence to beach closure advisories is paramount for public safety.These recurring environmental challenges emphasize the importance of ongoing water quality monitoring and proactive measures to protect both public health and the ecological integrity of our state’s valuable aquatic resources.

Recent Beach Closures & Safety Concerns (July 20, 2025)

Several Massachusetts beaches are currently under temporary swimming bans due to elevated bacteria levels. This impacts popular coastal destinations and raises concerns for residents and tourists alike. Understanding why these closures happen, where they are occurring, and how to stay safe is crucial for anyone planning a beach trip. This article provides the latest facts on beach water quality, swimming advisories, and resources for checking current conditions.

Why Are beaches Closing? Understanding the Causes

The primary reason for temporary beach closures in Massachusetts is high levels of bacteria, specifically enterococci. These bacteria indicate the presence of fecal contamination, which can come from several sources:

Stormwater runoff: Heavy rainfall washes pollutants, including animal and human waste, into waterways and ultimately the ocean. This is a major contributor to temporary spikes in bacteria.

Combined sewer Overflows (CSOs): In some older coastal communities,combined sewer systems carry both stormwater and sewage. During heavy rains, these systems can overflow, releasing untreated wastewater into nearby waters.

Wildlife: Seabirds and marine animals contribute to bacteria levels, notably in areas with large populations.

illicit Discharge: Illegal dumping or leaks from septic systems can also contaminate beach water.

Warm Water Temperatures: Higher water temperatures can promote bacterial growth.

These contaminants pose a health risk to swimmers,potentially causing illnesses like gastrointestinal infections,skin rashes,and ear infections. Beach safety is paramount, and closures are implemented to protect public health.

Current Beach closures & Advisories (as of July 20, 2025)

As of today, July 20, 2025, the following beaches are under swimming advisories or are completely closed:

Crane Beach, Ipswich: Closed to swimming due to high bacteria levels following recent rainfall.

Singing Beach, Manchester-by-the-Sea: Swimming advisory in effect; water samples exceeding safe levels.

Nahant Beach: Temporary closure announced this morning due to elevated enterococci counts.

Revere Beach: Partial closure – the section near the MBTA station is closed; other areas remain open but are under increased monitoring.

Carson Beach, Boston: Swimming advisory; testing ongoing.

Castle Island,Boston: Open for recreational activities,but swimming is not advised.

Note: This list is subject to change. Always check official sources before heading to the beach.

How to Check Beach Water Quality & Swimming Status

Staying informed is the best way to ensure a safe beach experience. Here are reliable resources for checking Massachusetts beach conditions:

1. Massachusetts Department of Public health (DPH) Beach Monitoring Program: https://www.mass.gov/info-details/beach-monitoring-program – This website provides up-to-date information on water quality testing results for public beaches across the state.
2. Local Health Departments: Each coastal town and city has a health department that monitors its beaches. Check their websites or call them directly for the latest information.
3. Swim Safe App: A mobile app providing real-time beach water quality data. (Available on iOS and Android).
4. News Outlets: Local news stations and websites often report on beach closures and advisories.

Understanding Beach action Levels

The Massachusetts DPH uses a tiered system to classify beach water quality:

Safe: Water samples meet all state and federal standards for recreational use.

Advisory: Water samples exceed acceptable levels, but the risk of illness is considered moderate.Swimming is not recommended, especially for individuals with compromised immune systems.

Closure: Water samples substantially exceed acceptable levels,posing a high risk of illness.Swimming is prohibited.

Protecting Yourself & Others: Beach safety tips

Even when beaches are open, it’s critically important to take precautions:

Avoid Swimming After Heavy Rainfall: Wait at least 24-48 hours after a significant rain event before swimming.

Don’t Swim Near discharge Pipes: Stay away from areas where stormwater or sewage discharge pipes empty into the ocean.

Cover Cuts and Wounds: Bacteria can enter the body through open wounds.

Avoid Swallowing Water: Try to avoid swallowing water while swimming.

shower After Swimming: Shower with soap and water after leaving the beach.

Report Illnesses: If you experience symptoms of illness after swimming, contact your doctor and report it to the local health department.

The Impact of Climate Change on Beach Water Quality

Climate change is exacerbating the problem of beach contamination. More frequent and intense rainfall events lead to increased stormwater runoff and CSOs. Rising sea temperatures also promote bacterial growth. addressing climate change is crucial for protecting the long-term health of massachusetts beaches and ensuring safe recreational opportunities for future generations.
