The (old) foodblog Khymos has an excel sheet to calculate what salts to add to get different mineral waters starting from the known composition of your own tap water: https://khymos.org/2012/01/04/mineral-waters-a-la-carte/

Trying it out is still on my list; it's not easy to get food-grade necessary salts...
