Are there parasites in beach sand?

Do beaches carry bacteria?

Many beaches may be contaminated with fecal bacteria, which can lead to gastrointestinal issues. Avoid swimming after it rains and wash your hands regularly to cut down on your chances of getting sick at the beach. Check with your local health department to determine if your beach is safe for swimming.


How do beaches get fecal bacteria?

Some cities also have joint sewer and stormwater systems that can overflow—this leads to “a mixture of raw, untreated sewage and stormwater” that can sometimes flow onto recreational beaches, said Rumpler. Runoff water from large farms can sometimes also contaminate beaches, he added, as can feces from wildlife.


What are the symptoms of beach bacteria?

Another potential source of illness includes some types of cyanobacteria that form algal “blooms” (discolored water) and the toxins they produce. When people are exposed to cyanotoxins, they may have hay fever-like symptoms, skin rashes, sore throat, cough, nausea, vomiting, diarrhea, or even kidney or liver damage.


Why do beaches close for bacteria?

The two most common reasons for beach closures are elevated concentrations of E. coli and/or cyanobacteria (blue-green algae) blooms. Below, we specifically discuss E. coli and what it means for our lakes and beaches.


What causes high bacteria levels at beaches?

A: Bacteria in coastal recreational waters can come from a variety of sources, both near the shore and inland. These sources include development, sewage treatment plants, septic tanks, storm water runoff, boating waste, humans, and animals.


Do all beaches have E. coli?

Not necessarily. Beach water quality problems are often localized because our lakes are so large. A number of beaches tend to experience high E. coli after a large rainstorm when contaminants on land can be quickly delivered to the lake.
