Okay, if soft water is widely considered to be a significant cause of heart
disease, what's the simplest way of hardening a supply of drinking water in
a domestic situation where the supply is naturally very soft?

Add minerals!

As this is DIY: There is a "mineral water calculator".

One makes mineral solutions, using (checks): Plaster of Paris, Epsom salt,
Chalk, Baking soda, Table salt, Milk of magnesia, Slaked lime.

Then enter the analysis of your tap water in a spreadsheet, available form your
water supplier in many cases. Then select, for example, a precocious mineral
water from the lower Himalayas rich in salty tones, and the spreadsheet tells
you how much of what to add (or if your tap water already contains too much of a
mineral to get there from here).

Carbonation is an extra step.

Alternatively, usenet participants can scape the kettle fur from their kettles,
water heaters, and bathroom tiles, and mail it to less fortunate
participants.... (This may require some carbonic acid to dissolve the minerals.)
