Good day.
There are numerous studies that provide evidence that people become ill or die more frequently and/or earlier as a result of ingestion of aluminium or aluminium compounds. Epilepsies, abnormal forgetfulness states, skin sensitivities or diseases or Alzheimer's disease are observed (according to the report in phoenix "Die Akte Aluminium" on 16.12.2014 e.g. doubling of Alzheimer's disease in people over 60 years of age with increased aluminium values in the body).
However, drinking water is treated worldwide with aluminium compounds, which can lead to traces of aluminium in drinking water due to production (instead of e.g. harmless iron compounds).
How do the Hamburg waterworks handle drinking water treatment? Do you also rely on aluminium compounds?
