Desperate for Water? Here’s Why Pool Water Could Be Dangerous

In an emergency, when your usual water supply is compromised and you don’t have a good backup, you might wonder if swimming pool water is safe to drink. The quick answer is: unless you have no other option, do not drink pool water, and even then, only after treating it to make it safe.

Your pool holds a large volume of water, but it is treated with chemicals like chlorine to prevent algae and bacteria growth. These chemicals make it unsafe for consumption.

Drinking small amounts of pool water might not cause immediate harm due to the low concentration of chemicals. However, using pool water as your main source of hydration during an emergency is not advisable. Although pool water looks clear, it contains chemicals that make it different from drinking water.

For safety, always treat pool water before drinking it. Boiling the water, using water purification tablets, or employing a water filter can help remove harmful substances. It’s essential to prioritize safe drinking water to avoid health risks in any emergency situation.

What’s In Water From Swimming Pools?

Before considering the use of water from a pool as an emergency water supply, you need to understand its composition, which includes various chemical properties, potential biological contaminants, and its physical characteristics. You also have to consider the unpalatability and danger of water from salt water pools.

Chemicals

Swimming pool water contains chlorine or bromide as disinfectants to kill harmful microorganisms. These chemicals are essential for maintaining pool hygiene but can be harmful if ingested in high quantities.

Cyanuric acid is often present as a stabilizer for chlorine, helping to protect it from rapid degradation due to UV light. Some pools use a salt system that generates chlorine through electrolysis. It’s essential to note that levels of these chemicals are usually high in pool water compared to drinking water standards.

Biological Contaminants

Despite chemical treatment, alongside the harsh chemicals, the water in swimming pools may still harbor bacteria, viruses, human skin cells, animal waste, fecal matter, and other contaminants, even with a good water filter in place.

The efficacy of chlorine can be reduced by ammonia from sweat or urine, leading to the formation of chloramines, which can be less effective at disinfection. Your risk of exposure to pathogens increases if the pool is not properly maintained. And if it’s a pool shared by lots of people, you’re looking at a very unpleasant “people soup”. Gross.

Physical Characteristics

The physical characteristics of pool water—such as its clarity, color, and smell—are influenced by its chemical and biological makeup.

For instance, clear water indicates effective filtration and proper chemical balance, while cloudy water can signal the presence of fine particles or microorganisms. An unusual odor may suggest an imbalance of chemicals, possibly due to contaminants.

Health Risks of Drinking Pool Water

In an emergency, you might be considering drinking water from a swimming pool, but it’s critical to understand the health risks involved. Water in most pools contains hypochlorous acid and other chemicals, as well as potential contaminants that can pose serious health risks if consumed. So between the chemicals and all the germs, pools don’t make a good drinking water source.

Chemical Exposure

Your risk of chemical exposure increases with the consumption of swimming pool water. Pool water is often treated with chlorine to kill germs, but the interaction between chlorine and organic matter, such as skin cells and body oils, can form chloramines.

Consuming water with high levels of chloramines can lead to respiratory issues and irritate your skin and eyes. Additionally, cyanuric acid is commonly used in pools to stabilize chlorine levels; however, it can be harmful if ingested in large amounts.

  • Harmful Chemicals: Common pool chemicals like chlorine can transform into toxic compounds.
  • Cyanuric Acid: Stabilizes chlorine but can become hazardous in excessive concentrations.

Waterborne Pathogens

Despite chemical treatment, pools can still harbor waterborne pathogens such as giardia and cryptosporidium, which are highly resilient to chlorine disinfection. If you consume water contaminated with these parasites, you might experience gastrointestinal illness characterized by diarrhea, cramps, and dehydration.

  • Giardia: Can cause prolonged diarrheal illness.
  • Cryptosporidium: Extremely resistant to chlorine, leading to severe, acute gastrointestinal symptoms.

Emergency Water Sources

Before considering any water source, it’s vital to evaluate its safety. Start by checking bottled water supplies, which are the most reliable option for potable water. If this isn’t available, you may turn to tap water, provided it hasn’t been contaminated. Utilize resources like Google Earth to locate nearby natural water sources, but remember, these must be treated before consumption. Always include water storage as part of your emergency preparedness plan to ensure a steady supply when needed.

Swimming Pool as an Emergency Source

Swimming pools can serve as an emergency water source, but only in very specific circumstances. The water, typically treated with chemicals, requires proper handling to become safe drinking water. Firstly, avoid pools with high levels of chlorine or other harmful substances. If it’s your last resort, you can employ techniques like distillation or using a water filter to make pool water drinkable. However, this isn’t a substitute for a dedicated emergency preparedness strategy focused on maintaining a supply of intentionally stored, treated water.

Filtration Methods

To remove debris and other particulates from pool water, start with a filter. Using items such as a clean cloth, coffee filter, or paper towel can serve as a preliminary step to sieve out larger particles. For more thorough filtration and water purification, consider portable water filters like LifeStraw, which have an absolute pore size small enough to filter pathogens from water. Commercially bottled water often goes through similar filtration processes, making them a safe alternative.

Disinfection Processes

After filtering, it’s essential to disinfect the water to eliminate microorganisms. UV rays can neutralize many pathogens if sunlight is abundant. However, chemical disinfectants, such as bleach (specifically sodium hypochlorite), iodine, and chlorine dioxide tablets, are more reliable.

To use bleach, add approximately 8 drops of 6% to 8.25% sodium hypochlorite per gallon of clear water. Always ensure the correct chlorine level; typically, 1-2 milliliters per liter is sufficient to purify pool water and make it safe to drink.

Boiling Water

Boiling water is a highly effective method to disinfect and purify swimming pool water. Bring the water to a rolling boil for at least one minute to kill most pathogens. If you’re at elevations above 6,500 feet (1981 meters), extend boiling time to three minutes.

Once cooled, transfer the water into sanitized containers to avoid recontamination. Remember, this process will not remove chemical contaminants, so it’s best used in conjunction with other methods for achieving clean water.

Preparing for Emergencies

Your swimming pool can serve as a significant emergency water reserve. To ensure its water quality, maintain proper chlorine levels and balance the pH routinely. For saltwater pools, the salt cell should be kept clean to work effectively. In case of a boil water alert, you might need to rely on this water for tasks such as washing dishes or as a part of your water treatment system. Make sure you have a fuel-powered generator to run the pool’s pump and filtration system during power outages, as this will help keep the pool water in a better condition for longer periods.

Emergency Disinfection Supplies

Have a supply of chlorine bleach on hand since it’s essential for water sanitation. Use a teaspoon to measure bleach for disinfecting small quantities of water. Always remember that disinfectants like bleach cannot fully purify water with contaminants such as heavy metals or pesticides. During a survival situation, know the procedures from sources like the CDC to use bleach correctly. Gather additional supplies like a scoop for handling and a pot for boiling water if needed. Be aware that boiling pool water will not remove chloramines and other chemical treatments but is effective against pathogens.

Safety Guidelines

When pool water needs to be purified, consider boiling as a primary method; bringing water to a rolling boil for at least 1 minute kills most pathogens. In high altitudes, increase the time to 3 minutes. In the absence of chemical disinfectants, exposure to sunlight can help to reduce pathogens, but this should only be a last resort and might not be reliable. Always seek alternative safe water sources whenever possible to reduce the risk inherent in using treated recreational water for drinking.

Practical Considerations
