    What I heard is that we have such hard¹ water where I live (ancient city center), to protect against lead. No idea if that’s an urban legend or not.

    ¹17 dH, 3.036 mmol/l, 6.071 mval/l,21.303 °e

      This is true. Hard water reduces the amount of lead that can leach into water. I don’t know the specific concentrations etc, but it is true.

        I know it’s true, I just don’t know if it’s true that that’s why we have such hard water (that I need to filter with Brita plastic filters …)

          Do water filters filter out microplastics? Although if they did i’m not too sure of the effectiveness, aside from removing maybe unsafe quantities… mainly because most filter jugs are usually made out of plastic

        Fun fact, when romans introduced lead pipes through aqueducts across the empire, the lead didn’t affect all populations equally because of this. Hard water regions were mostly spared. Turns out the layer of limescale that forms on pipes is also good at stopping the lead leaching.
