Beach season is now in full swing, but travelers may want to check their local water-quality reports before heading out for a day on the shore. 

According to multiple reports, officials in several states have issued health alerts or closed popular beaches entirely after water testing revealed high levels of bacteria that could pose risks to swimmers. The warnings span various U.S. regions, impacting areas such as Iowa, Massachusetts, New Jersey and Washington state.

These latest advisories reinforce ongoing concerns about the nation’s beaches. A report released last year by the Environment America Research & Policy Center revealed that "61% of U.S. beaches had potentially unsafe contamination levels in 2024," according to Fox News.

The organization noted that unhealthy water conditions are often due to fecal matter from sewage overflows, urban runoff and waste from large-scale farming. 

Iowa

The Iowa Department of Natural Resources (DNR) is advising people against swimming at six beaches across the state after routine testing detected elevated levels of E. coli bacteria, including at Backbone Beach, Pine Lake South Beach, Geode Lake Beach, Union Grove Beach, Pleasant Creek Beach and Nine Eagles Beach.

According to the Centers for Disease Control and Prevention (CDC), normal E. coli bacteria naturally occur in a healthy digestive tract, but some strains can cause serious illness, particularly among young children, older adults and people with weakened immune systems. 

The Iowa DNR keeps an updated webpage where beachgoers can check current conditions at the state’s various beaches, whether they’re open for swimming, under a health advisory, closed completely, subject to special status, or there’s insufficient water-monitoring data. 

Massachusetts

Massachusetts has also had several beach closures this month due to water-quality issues, including high bacteria levels and toxic blue-green algae. Affected locations include Damon Pond Beach, the two Cliff Pond beaches, Cochituate State Park, College Pond, both Fearings Pond beaches, Forest River and Juniper Point, according to NBC Boston.

The Massachusetts Department of Public Health provides the public with an Interactive Beach Water Quality Dashboard that updates water-testing data and beach status hourly throughout the swimming season. 

New Jersey

Meanwhile, Fox Weather reported that health officials in New Jersey recently issued swimming advisories for eight beaches and lakes after testing found high levels of fecal bacteria. The affected locations include Ferry and Bay, Baywyn and Bay, Wildwood and Bay, Cedar Point Beach, Beachwood Beach West, Mirror Lake, Sleepy Lagoon and Vernon Valley Lake. Authorities closed Beesley’s Point Beach altogether.

Washington

On the West Coast, the State of Washington’s Department of Ecology beach advisory map indicated that swimmers should be cautious about entering the water at Freeland County Park/ Holmes Harbor, Walker County Park, Squaxin Park, Little Squalicum Park, West Bay Park and Thea Foss Waterway because "increased levels of bacteria are present, and a swimming advisory is issued by a local health department."

A few of these swimming advisories are actually marked as “permanent,” due to ongoing water-quality concerns.  

The City of Kent also announced that the beach at Lake Meridian Park is currently closed due to elevated bacterial levels. 

Elsewhere in the U.S.

At the same time, on the other side of the country, beaches are being made inhospitable in states like Florida by a record-setting surge of sargassum seaweed washing up onshore. Not only does sargassum clog up beachgoer access to the sand and surf with unsightly, smelly clumps of algae, but it also releases ammonia and hydrogen sulfide as it decays, which can adversely affect the health of those exposed to it.
