Swimming in the ocean or one of South Carolina’s lakes and rivers is an excellent outdoor activity for the whole family and a great way to cool off during the hot summer months. However, outdoor activities in a natural waterbody can pose some risks, so it’s important to be aware of safety guidance to protect yourself and others.  

Natural waterbodies aren’t chemically treated like swimming pools, so the risk of coming into contact with potentially harmful bacteria, viruses and other organisms is always a potential. SCDES performs regular testing of our state’s ocean water, lakes and rivers to help monitor water quality to keep you informed. Learn more below. 

 

In addition to sunscreen, beach towels and an umbrella, you’ll want to bring an awareness of local beach conditions and ordinances as you enjoy a day in the sand, such as:

  • whether lifeguards are on duty
  • rip current safety
  • weather forecasts and tidal cycles
  • local beach ordinances and rules
  • any nearby long-term or short-term swimming advisories

CheckMyBeach.com is an excellent beach-goers' resource for beaches along the Grand Strand. SCDES’s Beach Monitoring webpage is another important tool for checking long-term and short-term swim advisories.  

SCDES monitors ocean water at 122 collection points along the coast during the busy summer months, and if certain bacteria levels are too high, the agency issues a short- or long-term swim advisory to help protect people from potential health impacts. A swimming advisory doesn’t mean a beach is closed — if a swimming advisory is in place, you should avoid swimming in the water at the collection point until the advisory is lifted.

Just like the ocean, South Carolina lakes and rivers are great places to cool off but there is always the risk for coming into contact with bacteria, viruses, algae or other organisms that could make you sick.  

SCDES monitors the water quality of our state’s lakes and waters to keep the public informed as they plan a day in the water.

  • Swimming advisories - SCDES collects water samples at South Carolina lakes and rives twice a month and analyzes those samples for bacteria levels. If certain bacteria levels are elevated, a short- or long-term swim advisory is issued, and it’s advised that swimming not take place in that part of the lake or river until bacteria results have returned to normal.

  • Harmful algal blooms - Algal blooms are naturally-occurring in lakes, ponds, and rivers and they are comprised of tiny plant-like organisms. Certain species can produce toxins that can make people and animals sick. When an algal bloom contains toxins or is comprised of a species that has the potential to produce toxins that are known to affect the health of people, animals, and the environment, they are known as harmful algal blooms (HABs). 

If SCDES identifies a HAB, the agency issues a Recreational Water Watch with specific recommendations for protecting people’s health. Learn more on our HABs webpage.

Swimming safety is critical to enjoying our state’s beaches, lakes and rivers while making sure you, your friends, and your family stay safe and healthy. It’s always recommended to:

  • Be aware of swimming advisory signs.  
  • Do not go swimming or rafting during a storm or right after it rains.  
  • Avoid swallowing river, stream, lake, or ocean water.  
  • Never swim alone. Always bring somebody with you.  
  • Avoid swimming in still, warm or muddy water.  
  • Never dive into shallow water or where you cannot see the bottom.  
  • Never use alcohol or drugs while swimming or boating.  
  • Never swim with deep cuts or wounds.  
  • Hold your nose if jumping or diving into natural water 

Gastroenteritis is the most common illness associated with swimming in contaminated water. It occurs in a variety of forms that can have one or more of the following symptoms: nausea, vomiting, stomachache, diarrhea, headache and fever.  

Other minor illnesses that can result from swimming in contaminated water include ear, eye, skin, nose, and throat infections. Small children and individuals with weakened immune systems are most at risk of illness.

To stay safe and healthy at the beach:

  • Be aware of advisories and avoid swimming in those areas. Wading, fishing and shell collecting do not present a risk since most exposures to pathogens occur by swallowing water. However, do not enter the water with open sores or lesions, high levels of bacteria may cause infection.
  • Do not swim or allow children to play in swashes or near stormwater pipes. Although the shallow pools of water on the beach caused by swashes and stormwater seem like good places for children to play, these shallow pools are caused by runoff from paved surfaces and often contain much higher levels of bacteria than the ocean.
  • Do not swim in the ocean or in the river during or immediately following rainfall. To further reduce risk of illness, wait at least 48 hours after a heavy rain to resume swimming. Heavy rain can wash bacteria and possibly harmful pathogens into the surf. High bacteria densities persist in the surf for hours after these rains and may increase swimmer's risk of illness. 

SCDES also has a critical role in helping keep people safe at public swimming pools. Our pool inspectors perform routine inspections of public swimming pools, spas, waterparks, splash pads and more to help ensure they’re being operated in compliance with state and federal laws and regulations that keep people safe.
