Safeguarding Your Family from Aluminum in Drinking Water

Summary
Aluminum in drinking water poses health risks and requires attention to safeguard families. Originating from natural sources and treatment processes, aluminum exposure can lead to neurological issues and bone disorders. Regulations set limits, but testing water for aluminum is crucial. Filtration systems like reverse osmosis offer solutions, but balancing cost and effectiveness is key. Bottled water isn’t always a safer alternative. Taking action involves investing in filtration, regular testing, staying informed, and advocating for clean water.
Aluminum is Earth’s third most abundant element.While naturally occurring and something we’re often given a trace quantity of, it’s not a necessary nutrient for the human body. Even if too much is, health problems can result. You see aluminum in everything from ovens and cookware to antacids and processed foods.
But one of the least talked about sites for aluminium’s impact is in our drinking water. The metal might leak into the water from the ground or get sucked in during water treatment. But what about our wellbeing? And what can we do to limit our exposure? To be able to say yes to these questions, we need to know something about what’s at stake with aluminum.
Aluminum in Drinking Water: How does it get there?
But before we can start to fix the problem, let’s get a handle on the way aluminum gets into our drinking water. Aluminium emulsifies from the crust of the planet and could enter waterways. Moreover, water in many municipal water treatment plants is treated with aluminium coagulants. This procedure can leave some aluminum in the treated water.
Even more challenging is the fact that the solubility of aluminium varies with water’s pH. This means the percentage of aluminum in water will vary significantly based on many variables, such as water source and treatment processes.
Health Risks Associated with Aluminum Exposure
Aluminium is also an issue because of the health implications. The human body excretes some amounts of aluminum effectively, but in excess of that amount, it’s toxic over the long run. Aluminium toxicity has been linked to everything from brain damage to bone and anaemia.
There’s evidence, for example, that aluminum is connected to Alzheimer’s. Although not definitive, the correlation is concerning. Likewise, aluminum depletion could cause the body to fail to absorb some of its vital nutrients, which could cause bone defects. These are health hazards that should not be overlooked in decreasing the exposure to aluminium, especially in the form of water.
Regulations and Guidelines Regarding Aluminum in Drinking Water
As the health hazards of aluminum became known, guidelines and standards for aluminium content in water have also been developed. These guidelines vary globally. In the World Health Organization (WHO), for example, it recommends 0.2 mg/L. The US Environmental Protection Agency (EPA) on the other hand, has not established a mandatory limit, but recommends a secondary maximum contaminant concentration between 0.05 and 0.2 mg/L.
These are based on health effects of aluminium. But they also consider technical feasibility and price of water treatment.
Testing Your Water for Aluminum: How and Why?
So how can you tell if your water from the tap is teeming with aluminium? The solution is water testing. Some labs and companies have home water test kits. These kits normally consist of a drop of your tap water being returned to the lab for testing.
The value of water testing is not overstated. Not only is it aluminum; your water might be testing for any number of other contaminants. Also, you’ll be able to determine the water quality of your water to decide which treatment is best for your home.
Filtering Aluminum Out: Types of Water Purification Systems
Depending on the level of aluminum you’re trying to remove from your water, there are several kinds of filtration equipment that will work. Reverse osmosis systems, for example, remove most of the aluminium. Likewise, activated alumina filters are used to get rid of aluminum and heavy metals.
But all filtration options have pros and cons. Reverse osmosis machines, though extremely effective, are very expensive and require much care. Activated alumina filters are cheaper, but can miss out on some other potential contaminants. When considering a filtration system, cost, performance, and convenience all come into play.
Bottled Water vs Tap Water: The Aluminum Debate
The question most frequently asked about water and aluminum in it is bottled water, is it safe? Note that bottled water isn’t always 100% aluminum-free. Indeed, there are even reports that some bottled waters might have more aluminium than tap water.
Bottled water has issues too. And that’s a lot more expensive than plastic waste. So, there isn’t necessarily a silver bullet when it comes to the aluminum-free water you can get from bottled water.
Taking Action: Steps to Reduce Your Family's Exposure to Aluminum
You’re probably thinking, now, how do you protect your family from aluminum? Here are a few suggestions:
Buy a water filter: As I mentioned earlier, there are water filters that remove the aluminum. Invest in one if you can afford it.
Don’t skimp on water testing: Water tests should help you monitor your water for levels of aluminum.
Make sure to stay educated: Stay current with the latest studies and recommendations about aluminum in water.
Water for health: Volunteer in local community projects for clean water and health.
Think about your total aluminium exposure: Though this post is about drinking water, it’s only one of the aluminum-containing sources you can have in your body. Try the other sources, including food, kitchen appliances, and cosmetics, and make sure you aren’t being overwhelmed.
Protecting your family from aluminum can be a difficult feat, but with the proper information and resources, it’s not impossible. Make the jump today and one day at a time towards a healthier you.
