In German, we have a verb "verschlimmbessern", which means to make something
worse by improving it. I agree with Warin that water_source=potable does not
seem right. It mixes source (origin) and target (use). water_source=* may be
fine with another set of values, and *=potable may be fine with another key
(drinkable=* and drinking_water=* are in use, and water:quality=* and
water_purity=* were suggested in this discussion).
