Aluminum in Drinking Water: Health Risks, Sources, and How to Remove It
Aluminum is a naturally occurring inorganic element that can be found in drinking water supplies. It is classified under the category of inorganic contaminants. The U.S. Environmental Protection Agency (EPA) has set a Maximum Contaminant Level (MCL) of 200 μg/L for aluminum.
Health Effects
At standard levels, aluminum in drinking water is not generally considered highly toxic. However, exposure to very high levels of the contaminant may lead to possible neurological effects. It is important to monitor and maintain concentrations within recommended guidelines to prevent potential health impacts.
How Aluminum Gets Into Tap Water
Aluminum can enter the drinking water supply from natural environmental sources, such as natural deposits in the ground. It can also be introduced into the water distribution system through residuals left behind during municipal water treatment processes. These two pathways are the primary sources of aluminum in tap water.
How to Remove Aluminum From Your Water
The reduction and removal of aluminum from drinking water is typically achieved by municipal facilities. This is done through coagulation and filtration optimization within the water treatment plant. Ensuring these treatment methods are properly optimized helps keep aluminum levels safe for consumers.
Should You Test Your Water?
You can check aluminum levels in your municipal water by reviewing your local water provider's annual consumer confidence report or searching on WaterQ. Those who get their water from private wells may also choose to periodically test their water through a certified laboratory. You can also look up your local water system on WaterQ or check the Aluminum data page for reported levels in your area.
Frequently Asked Questions
Is Aluminum dangerous in drinking water?
Aluminum is not considered highly dangerous at normal concentrations, reflecting its moderate severity weight. However, exposure to very high levels of aluminum has been linked to possible neurological effects. Keeping concentrations below standard guidelines ensures it does not pose a health risk.
How does Aluminum get into tap water?
Aluminum typically gets into tap water from natural deposits in the earth or from residuals remaining after water treatment processes.
How can I remove Aluminum from my water?
Aluminum is removed from drinking water supplies by optimizing treatment methods such as coagulation and filtration.
