Why does bottled water taste metallic is not a new question but the answer depends on the cause of the metallic taste. Did you know that the metallic taste in your bottled water might be affecting more than just your palate?

Recent studies have found that the presence of heavy metals in drinking water can pose serious health risks, including damage to the liver, kidneys, and nervous system.

While the cause of the metallic taste in bottled water can vary, from the materials used in bottling to the composition of the water itself, understanding its source and potential impact on your health is critical.

In this article, we will explore the latest research on the metallic taste in bottled water, its causes, and strategies for minimizing its effects, so you can make informed decisions about the quality and safety of your drinking water.

Why Does Bottled Water Taste Metallic

The metallic taste in bottled water can have various causes, ranging from natural minerals and contaminants to human-made factors such as packaging and storage conditions. Here are some of the most common causes:

1. Presence Of Actual Metal Content

The presence of actual metal content in bottled water can contribute to a metallic taste. This can occur due to a variety of reasons, such as the leaching of metal ions from pipes and other infrastructure, contamination of the water source by heavy metals, or exposure to metal during the bottling process.

Metals such as lead, cadmium, and mercury can pose serious health risks if consumed in high amounts.

Exposure to these metals over time can cause a range of health problems, including damage to the liver, kidneys, and nervous system.

2. An Excess Of Trace Minerals

An excess of trace minerals can also contribute to a metallic taste in bottled water. Trace minerals such as iron, manganese, zinc and copper are essential nutrients that are needed in small amounts by the human body.

These minerals are naturally occurring and can be present in the soil, rocks, or water sources. When water passes through these minerals, it can dissolve and pick up their metallic taste.

However, when they are present in excess amounts in drinking water, they can alter the taste and potentially cause health problems.

For example, high levels of copper in drinking water can cause gastrointestinal problems and damage to the liver and kidneys. Iron in excess can cause stomach pain, constipation, and other health problems.

3. Contaminants

Some contaminants, such as algae, bacteria, or chlorine, can also affect the taste of water and give it a metallic or chemical flavor. Chlorine, for instance, is commonly used as a disinfectant in water treatment plants, but it can leave a metallic aftertaste in water if not properly treated.

4. Low pH Levels

Low pH levels of water can also contribute to a metallic taste in water. This is because acidic water can cause metals such as copper, iron, and zinc to dissolve and become more present in the water, resulting in a metallic taste.

The pH of water is measured on a scale of 0-14, with 7 being neutral. Water with a pH below 7 is considered acidic, while water with a pH above 7 is considered alkaline.

The pH of water can be influenced by a variety of factors, including the composition of the water source, water treatment processes, and the materials used in water infrastructure.

For example, pipes made of copper or iron can release these metals into the water, lowering the pH and contributing to a metallic taste.

It’s important to note that while low pH levels can contribute to a metallic taste in water, acidic water can also be harmful to human health. Drinking water with a pH below 6.5 can increase the risk of lead exposure from pipes and other infrastructure.

It’s recommended that pH levels of drinking water should be maintained between 6.5 and 8.5 to ensure both safety and taste.

5. Packaging And Storage

The materials used in bottling, storage, and transportation can also affect the taste of bottled water. For instance, plastic bottles can release chemicals such as bisphenol A (BPA) or phthalates, which can affect the taste and odor of water.

Similarly, metal containers, such as aluminum or steel cans, can affect the taste of water if they corrode or react with the water.
