Yeah but groundwater has its flaws as well. Arsenic is a common contaminant found in groundwater. Hopefully you are getting your water tested periodically to make sure the aquifer is still producing high quality groundwater.

The chlorine and fluoride really depend on your local municipality and how well they treat the water. If the chlorine level is too high then the operators aren’t dosing correctly and fluoride addition is a local governance issue. Big dental psyop’ed us into thinking it prevents cavities for the poor and marginalized.

Taste and aesthetics comes down again to the governance and how much the citizens want to invest to have great tasting water. Most people want to pay as little as possible and to that you get what you pay for.
