Aluminum should not be detectable in mineral water. It builds up over time…in your brain. Yikes.
Lanjaron has no detectable levels of Aluminium…… https://www.purewaterproducts.com/articles/activated-alumina
“Leaching of aluminium from the activated alumina depends on the pH of the NMW and the alumina manufacturing process. In some cases levels between 100 and 200 microg/l were reported. However, based on data provided [5] by optimising the pH conditions and selection of the appropriate medium the aluminium release resulting from the process would normally not exceed 40-60 µg/l.”
Aluminium hydroxide is commonly used to filter tap water…. Another reason not to drink tap water. Instead, drink natural mineral water
