Summary
Identifying aluminum in drinking water is crucial for safeguarding health:
- Potential Sources: Aluminum can enter water naturally, via industry, or during treatment processes.
- Health Implications: Prolonged exposure may lead to neurodegenerative diseases or bone disorders.
- Detection and Prevention: Signs like changes in color or taste may indicate aluminum presence, but professional testing ensures accurate detection.
Life begins and ends with water and the health of the water we drink every day is everything. One that has been raised recently is the aluminium in our water supply. Aluminium is the metal that’s the most abundant metal in the crust of the planet. We have access to it all the time, from kitchen tools and soda bottles to food boxes and make-up.
The most interesting is that aluminium compounds are also used to clean water to remove toxins and bacteria. That makes our water clean and uncontaminated with pathogens, but it also means we can have aluminium in our water. The general ubiquity of aluminum also makes the question of whether it is a health threat a pertinent one.
With aluminium so ubiquitous, not all aluminum exposure is dangerous. We have body systems built to process certain quantities of most metals, such as aluminium. But exposures at consistently high doses over time are more than our bodies can absorb and remove the metal, which poses health risks.
Potential Sources of Aluminum in Drinking Water
There are many different routes that aluminum can travel into our water. Some of these include:
Nature deposits: Aluminum occurs naturally and leaches out of nature deposits into groundwater.
Pollution in industries: Aluminium from aluminum production and use could leak into the air and flow into waterways.
Process water: Water Treatment Plants : Aluminium salts are typically used to clean the impurities from the water. When left in place, a small amount of remaining aluminum can be found in the water treated.
Knowledge of these aluminum source is the first step towards determining and rectifying any aluminum contamination of water.
The Effects of Aluminum on Human Health
Concerning the health: Low levels of aluminum are generally considered harmless but, if used in large quantities over time, they can pose health problems. It has also been found that too much aluminum could be associated with neurodegenerative disease, bone degeneration and anemia.
Importantly, those health issues are tied to long-term intakes of high levels of aluminum. The typical person’s daily dietary and water intake of aluminum typically is much lower than these risks. But if you understand the potential health impact, then you’ll see why you should be concerned about aluminum in your drinking water.
Recognizing the Signs of Aluminum Contamination
There’s nothing easy about spotting aluminum in water because it’s usually tasteless, odourless and colorless. Here are some symptoms of aluminum in water:
Color change: When used in large amounts, aluminium can make water opaque or coloured.
Taste or odour changes: Aluminum does not taste or smell like much but can leave the water a bit bitter or awry.
Recall that these changes don’t prove that there’s any aluminum in them. Invest in water testing professionals for the gold-medal reagent of aluminum in water.
Scientific Testing Methods for Aluminum in Water
If you need to ensure that the drinking water is not riddled with aluminum, testing it in the lab is a must. The laboratories that measure water include atomic absorption spectroscopy, and inductively coupled plasma mass spectrometry, for aluminium and other metals.
If you’re looking for something a little more active, there are home testing kits. These can be a quick and convenient way to inspect for aluminium and other impurities. But they can’t be as accurate as lab tests.
Regulations and Safety Standards Regarding Aluminum in Water
It’s regulations and safety standards that keep our drinking water safe. These regulations dictate maximum levels of many pollutants such as aluminum. Around the world, the World Health Organization (WHO) recommends 0.2 mg/litre of aluminum in tap water. EPA in the US has no official threshold for aluminium but recommends limits that remain below 0.05 to 0.2 mg/litre. These regulations were developed to keep the amount of aluminium in our water at or around safe levels for humans to drink.
Preventing and Reducing Aluminum in Drinking Water
Once we’ve learned that aluminum is in our water, there are several steps to either lessen or remove it. These strategies include:
Filtration: There are water filters like reverse osmosis filters that will filter out the aluminum.
If you are using bottled water: Bottled water is typically more filtered and will not have any aluminum in it, so be sure to read the label to see how the water is filtered.
Controlling pH: Aluminum tends to leach more easily into acidic water. Adjusting pH will decrease the amount of aluminum that ends up in the water.
Such measures can make sure we stay as low-aluminum as possible in our water supplies to maintain our long-term health and wellness.
Why is regular water quality testing important?
In order to stay on top of aluminum sources and health concerns, it’s important to check the drinking water regularly for this risk. Water companies may control the quality of tap water but private well owners usually have responsibility for their water.
