I live in a relatively small town. It's serviced by 10 public source supply wells;these are arranged into districts. Each district has annual water quality reports posted for the last couple of years. From these reports, it's obvious about half of the wells share a common aquifer source. The others are mixed bag of well depths, overlying soils, drainage topology, geological strata differences, etc.
My district is no larger than 1/2 by 1 mile. It's by far the worst water of the 10 wells - pump placement is very shallow (less than 200 of the 650 ft total well depth, cased to 350', so not excuse for it being shallow except that its got adequate yield), very hard, and occasionally gets a heavy dosing of chlorine in the mixing well that primes/conditions the distribution system.
This water, like yours, kills off aroma and taste. My spendy tap filter cartridges are overwhelmed in 2 weeks, vs 2 months at another smaller city to the North, also groundwater fed, but with minimal water hardness due to it's proximity to the pristine main irrigation canal 'leakage' strata that provided much of the flow in the well. The Main Canal water quality matches the original supply (Columbia R, Banks Lake Reservoir, which is remarkably good water for a larger Western US river*.
My present water is so hard, I have no choice but to use bottled water for making tea, cooking and drinking water.
So it's plausible that your move put you in an other supply well source district, with comparatively poor water quality.
If your tea foams easily, but your soap has a hard time lathering up, you have problems**. You mention using bottled water for sincha. May as well use it for all your teas.
*based on a 2000 USDOI Interagency water quality assessment of 87 Western irrigation basins, it can be rated among the best in terms of low dissolved solids/minerals/organics and relatively little heavy metal and pesticide contaminants.
** Don't bother with tap and carafe filters; they haven't the capacity to provide deonization by zeolite resins when the water is hard-to-very hard.
