What’S In The Pool Water? [Updated!]

You might be getting hungry, but don’t eat the snacks by the pool. They could be contaminated with chemicals from the pool filter.

You’re probably aware that chlorinated water is dangerous to fish and other aquatic life. However, did you know that many pool filters are designed to contaminate the water with dangerous substances? There are five water pollutants that you need to be aware of. Let’s explore.

1. Chlorine

Chlorine is used in pools as a disinfectant and to create a relaxing atmosphere. While it might seem harmless, all it takes is one drink from the pool for your body’s chlorine levels to rise and cause damage. Did you know that swimming pools should not exceed 6 ppm chlorine? If the pool water is above this amount, then odorless and tasteless hypochlorous acid will form. This substance is extremely toxic to fish, crustaceans, and other aquatic life. The risk of irritation from the acidity is also very high. A single drop can cause severe burns on the skin, which in turn can lead to death. The good news is that it’s very easy for pool owners to stay below this amount. Simply use an acid neutralizer to decrease the acidity of the water.

2. Chlorine dioxide

This substance is a combination of chlorine and oxygen, which makes it extremely effective at removing ammonia and algae from water. In addition to pools, this safe and eco-friendly compound is used in industrial boilers and for air purification. There is no known threat to humans from chlorine dioxide, but it is toxic to fish and other aquatic creatures. The good news is that it breaks down rapidly into nontoxic compounds, including harmless hydroxyl compounds and chloric acid. It is also easy to monitor and handle safely.

3. Ammonia

Ammonia is one of the most dangerous substances in pools. Did you know that it is highly toxic to aquatic life and is responsible for large amounts of fish kills? The gas itself is also quite irritating, causing eyes to burn and skin to peel. Did you know that it is colorless, tasteless, and odorous? The good news is that it is relatively easy to remove from water with proper filtration. Simply install a pool filter with an attached media bag. As the ammonia goes through the cloth, it will bind to some of the fibers. Eventually the bag will become saturated, and it will need to be changed. Regular vacuum cleaning along with the installation of a water heater can assist in keeping the ammonia levels low in the water.

4. Nitrates

Nitrates are compounds that contain nitrogen and oxygen. They are found in some meats and dairy products, as well as some fertilizers. Nitrates have been known to accumulate in fish tissue and have caused several fish kills. This accumulation is called “nitrate poisoning”. Did you know that nitrates are very low in oxygen solubility, and this makes them relatively stable in water? While there is no evidence of nitrates creating an immediate threat to humans, it is known to accumulate in the blood over time and pose a threat to human health. The good news is that they are quite easy to remove from water through proper filtration. Simply install a regular pool filter and ensure that the water is changed frequently.

5. Aluminum

Did you know that aluminum is quite toxic to fish and aquatic creatures? In fact, it is on the UN’s List of Harmful Chemicals. Did you also know that it is quite acidic, even more so than hydrochloric acid? This makes it highly effective at dissolving bones and teeth. If you are in a pool with aluminum, then make sure that it is ionized by adding alkaline substances such as calcium chloride or lime. If that is not possible, then ensure that your pool is not directly above an ocean or lake because aluminum tends to dissolve in water, especially if it is not properly disposed of through proper filtration. Did you know that aluminum causes long-term health problems in humans, including Alzheimer’s disease? The good news is that it is quite easy for pool owners to monitor and handle safely.
