Natural Swimming Versus Pools, Which Has More Germs?

When it comes to swimming outdoors most people aren’t thinking about germs. After all, going for a swim in the local lake or river has gained tremendous popularity in recent years. For many, the allure of swimming outdoors provides the opportunity to bask in the sunshine, breathe in fresh air, and immerse oneself in the tranquil surroundings of the great outdoors. Aside from the locale, swimming outdoors also offers stress relief, the release of endorphins, calorie burning, and muscle exercise.

However, along with the joys of swimming in natural waters come inherent dangers. Unlike swimming pools, where conditions are carefully controlled, outdoor bodies of water pose unique risks. Swimmers are more vulnerable to tides, currents, and swells, which can be unpredictable and powerful. Additionally, the water may harbor hidden perils in the form of harmful bacteria and bugs. In certain areas, untreated sewage finds its way into rivers, lakes, and seas, making it challenging to find a safe spot for a refreshing dip.

One of the significant differences between swimming in a pool and swimming in natural waters is the level of water monitoring. Pools undergo regular testing and treatment to maintain cleanliness, whereas the composition of outdoor waters is constantly changing. Chemicals can leach into natural waters from nearby farms or industrial areas, and animals may defecate in the water, further increasing the risk of contamination. Moreover, the presence of toxic agents may not be readily apparent, and there might be no signposts warning of local dangers. When in doubt about the chemical safety of outdoor waters, it is better to err on the side of caution and avoid entering them. Trusting one’s instincts is crucial— if the water appears or smells off, it is wise to steer clear.

Another hazard specific to swimming in natural bodies of water is the presence of blue-green algae. This type of bacteria is naturally found in lake ecosystems, and during warm summers, it tends to multiply rapidly, forming a powdery green scum, known as a bloom, on the water’s surface. Unfortunately, these blooms can release toxins harmful to humans and occasionally fatal to pets. Swimmers who come into contact with or swallow water containing toxin-releasing algal blooms may experience skin rashes, eye irritation, severe gastrointestinal problems, fever, and muscle and joint pain.

Which Has More Germs a Natural Body of Water or a Swimming Pool?

In terms of swimming and germs, bacteria and viruses are the biggest risks. It’s a fact that swimming in natural waters is associated with a higher likelihood of contracting illnesses such as diarrhea. Sewage contamination is a common culprit, and swallowing contaminated water exposes swimmers to bacteria and viruses such as E. coli, Norovirus, and Shigella. Germs that cause other RWI’s include Naegleria fowleri and Pseudomonas. Additionally, rodents living in sewers near freshwater rivers or canals can carry the bacterial pathogen Leptospira, which causes Leptospirosis or Weil’s disease. The infection can occur when a swimmer ingests soil or water containing urine from infected animals or when it enters their eyes or a cut. Leptospirosis can lead to liver and kidney damage and, if left untreated, can be fatal. Swimmers can develop flu-like or jaundice symptoms within two weeks of swimming in a river, lake, pond, or other natural body of water.

Although safer than a natural body of water, there are still plenty of germs in pools.

Pools Are Far From Germ-Proof

This is not to say that swimming pools are necessarily germ-proof, quite the contrary, far from it. The primary cause of RWI’s (recreational water illness) in both treated and untreated swimming locations shared a common source: fecal matter, particularly human feces. Most germs responsible for these infections are transmitted through the fecal-oral route. In this process, an infected person swims in the water, and the pathogens are released from their anus into the water. Subsequently, another individual may swallow the contaminated water or inhale aerosolized droplets containing the pathogens.

For example, approximately 80% of illnesses contracted from treated water were attributed to Cryptosporidium, a parasite that resides in animal intestines and spreads by being excreted through feces into water sources. Although the illnesses resulting from untreated water were more diverse, the primary culprits still originated from fecal matter. Norovirus, a highly contagious virus transmitted through vomit and feces, accounted for about 30 percent of all cases. Additionally, the most common bacterial infection, Shigella, spreads through diarrhea.

While chlorine can effectively control many other pathogens that cause illnesses in pools and spas, Cryptosporidium can survive in chlorinated water for an extended period, surpassing a week. This prolonged survival allows the parasite to spread easily among swimmers in the contaminated water and subsequently infect others who come into contact with that water. Such scenarios contribute to the occurrence of outbreaks and the rapid transmission of the parasite.

Considering all these factors, it becomes evident that, despite occasional instances of urine and feces in pools, managed swimming pools still provide a much safer environment for swimming. When it comes to germs, pools with proper maintenance, including chlorine disinfection and pH regulation, are significantly less likely to harbor infectious microorganisms. Furthermore, the presence of trained lifeguards and safety equipment in pools reduces the risks of injuries and drowning incidents.

While swimming in natural bodies of water offers a captivating and immersive experience, it comes with inherent risks due to the presence of potentially harmful microbes and unpredictable water conditions. Swimming pools, on the other hand, provide a controlled and sanitized environment for recreational swimming. Therefore, when it comes to ensuring safety, managed swimming pools offer a more reliable option. They undergo regular monitoring and treatment, reducing the likelihood of waterborne illnesses and providing a safer space for swimmers. So, while the allure of swimming in a natural body of water is undeniable, it’s important to weigh the risks and take necessary precautions to ensure a pleasant and safe swimming experience.

French Diver Makes Splash After Flop At Opening of Olympic Pool

French Olympic diver, Alexis Jandard, created a memorable moment at the grand opening of Paris’s new Olympic pool, though not quite in the manner he had envisioned.

A startling video captured during the inauguration of the state-of-the-art Paris Aquatics Center on Thursday showcased the 26-year-old Olympian’s unfortunate landing on his right foot while gearing up to dive alongside two fellow athletes. Adorned in a Speedo reflecting the hues of the French flag, Jandard’s discomforting descent saw him landing on his back, ricocheting off the nearly 10-foot-high dive board, and somersaulting into the pool in a rather ungraceful manner.

The incident unfolded in front of a sizable crowd of onlookers, including French President Emmanuel Macron and various dignitaries. Jandard later displayed his scraped back on his Instagram account, maintaining a light-hearted approach to his embarrassing mishap by quipping, “For your information, my back is fine, but my ego…”

Sharing a photo of his reddened back, courtesy of the encounter with the diving board, on Instagram Stories, Jandard assured followers of his well-being. Speaking to RMC Sport, he recounted the unexpected turn of events, stating, “I’m fine. I didn’t hurt myself; unfortunately, these things happen. It happened at a time when I wasn’t expecting it at all.”

Reflecting on the incident, Jandard humorously noted, “I’ve broken boards before, but the board had never broken me before. Now it has.” Despite the hiccup, he maintained an optimistic outlook, remarking, “I would have preferred this ceremony to have gone well from A to Z. There was that little hitch. If it made people smile a little, so much the better.”

Explaining the mishap, Jandard clarified that his leg gave way upon landing but denied any slippage, emphasizing, “It’s a non-slip [board], and what’s more, the board was new, beautiful, and I think there’s still [some of] my back on the board there.”

With a silver and bronze under his belt at the 2022 and 2023 World Aquatics Championships, respectively, Jandard took the incident in stride, admitting, “It’s a shame, but it’s funny. When you take a step back, it’s funny.”

Looking ahead to the 2024 Paris Games this summer, where he is set to compete, Jandard acknowledged the inevitability of such occurrences in his sport, jesting, “These things happen,” while playfully lamenting, “It had to happen in front of the president and the whole of France. I think we chose the right moment.”

Despite being inundated with supportive messages and playful jabs, Jandard maintained a good-natured stance, urging his followers on Instagram, “Enjoy yourselves, make fun of me. I seriously deserve it!”

Earthquake in Taiwan Causes Waterfall From Rooftop Pool

In a harrowing turn of events, Taiwan was struck by a powerful 7.4 magnitude earthquake, leaving devastation in its wake. The quake, the strongest to hit the island in 25 years, shook the east coast of Taiwan, particularly affecting the city of Hualien and its surrounding areas. With a depth of 34.8 kilometers, the epicenter of the earthquake was located 18 kilometers south of Hualien, according to the US Geological Survey.

As rescue efforts are underway to free those trapped under rubble and debris, the toll of the disaster continues to rise. At least nine individuals have lost their lives, while over 900 others have sustained injuries. The aftermath of the earthquake has left over 100 buildings damaged, with reports of landslides and collapsed structures adding to the chaos.

The force of the quake was so immense that it caused a surreal sight—a rooftop swimming pool overflowing and cascading down the side of a building, creating an impromptu waterfall. Footage captured during the earthquake also shows the sheer force as a man inside a pool struggles to maintain balance, the water swaying violently from side to side.

Dramatic footage of the earthquake shows a rooftop pool transformed into a waterfall.

The region of Hualien County, with a population of approximately 300,000, faces immense challenges in assessing the full extent of the damage. Many inhabitants reside in remote coastal or mountain communities, making it difficult for rescue teams to reach them promptly. The precarious situation is exacerbated by the expectation of aftershocks, with 29 aftershocks greater than a magnitude of 4.0 already recorded near the epicenter.

Compounding the crisis are reports of miners trapped in two mines in Hualien, adding urgency to the rescue operations. Furthermore, over 91,000 households are grappling with power cuts, amplifying the difficulties faced by residents in the aftermath of the disaster.

Despite the widespread destruction, medical facilities in Taiwan’s capital, Taipei City, are functioning, albeit damaged. The Municipal Government has confirmed that hospitals are operating normally, providing critical care to the injured.

The international community has responded swiftly to the catastrophe, with the Biden administration monitoring the situation closely and expressing readiness to offer assistance. In the face of adversity, Taiwan is rallying its resources and resilience, demonstrating solidarity and resolve in confronting this natural disaster.

As the dust settles and the extent of the damage becomes clearer, questions arise about the effectiveness of early warning detection systems in mitigating the impact of natural disasters. Despite Taiwan’s investment in advanced seismic technology, including early warning systems designed to provide crucial seconds of alert before an earthquake strikes, many residents were caught off guard by the sudden and violent tremors. Reports indicate that the early warning detection system, while operational, did not reach a significant portion of the population in time to take preventive action

Patent Pending Apple Watch SOS Feature Could Prevent Drownings


A forthcoming feature potentially destined for the Apple Watch, as detailed in a recent patent application, could serve as a lifesaver for swimmers at risk of drowning.

Outlined in the patent is a capability for the Watch to identify “irregular behavior” and automatically trigger a distress call for assistance.

Apple underscores the alarming statistics surrounding drowning, particularly its prevalence among children, as a leading cause of accidental fatalities.

CPO Class - Virtual Online Classes - Become a Certified Pool Operator

In the United States alone, drowning claims the lives of over 3,500 individuals annually, ranking as the fifth most common form of accidental death. Tragically, a significant portion of these victims are children.

Emphasizing the critical importance of swift intervention during water emergencies, Apple highlights the dire consequences of prolonged submersion without resuscitation, which can result in brain damage and ultimately, drowning.

A Growing Need For Cost-Effective Wearable Solutions

While acknowledging existing underwater camera systems in some swimming pools aimed at detecting distressed swimmers and alerting lifeguards, Apple notes their costliness and unreliability.

Consequently, there’s a pressing need for a simpler, more cost-effective drowning prevention solution suitable for all types of water bodies, including public and private pools, as well as natural settings like lakes and ponds where installing underwater cameras is impractical.

The patent proposes leveraging wearable devices such as the Apple Watch for broader applicability, increased reliability, and the ability to detect various types of emergencies.

Alerting When Swimmers Are In Distress

For instance, if the Watch detects a wearer who is not proficient in swimming entering deeper water, it can promptly dispatch an alert instead of waiting for signs of distress.

These alerts can be transmitted to nearby devices, including those of friends and family, and seamlessly integrate with existing drowning detection and alarm systems to ensure lifeguards are promptly notified.

Apple Watches already boast capabilities to detect and respond to falls, vehicle accidents, and cardiac irregularities. Heartwarming testimonials featured in Apple’s “Dear Apple” video series show individuals whose lives were saved by these functionalities.

As with many patents from Apple, it’s important to note that not all concepts may materialize into actual products. Nonetheless, this innovation stands as a promising addition for potential integration into future watchOS updates.
