Tap water. I think it's pretty safe and the taste isn't bad. We have a whole house filter system that cleans it up more and helps the taste.
Like several communities in southern California, my city is spending a LOT of money (and tearing up all the roads) to put in "PURE WATER" (otherwise known as "toilet to tap"). When up and running, it will "recycle" waste water which will then be poured into an aquifer under the city (which also contains rain water)... that then will be further purified via a massage reverse omsemes plant and then mixed with imported water... about half of our water will be from the recycled waste water and the aquifer whereas now, 100% of it is imported (mostly from the Colorado River). All this will make us less dependent on imported water BUT more dependent on rainfall and this technology. And the cost of water will go WAY up. All this is part of a state mandate to find ways to reduce imported water. A neighboring city has a plant that uses sea water - another approach that is more socially accepted but also more expensive.
Blessings on your New Year!
